Work Text:
It started before either of them knew how to talk properly.
Izuku doesn’t really remember, but when he was younger, just four months old, he was on a play date, if you could even call two babies moving their limbs around a playdate, Kacchan’s parents gave their son something to eat that had a strong flavor and he didn’t like it. He babbled about the horrible flavor and the even worse texture.
It was just a full body waddle, a little tantrum cursing whatever his parents had fed him but that made Izuku make the sweetest happy sound. A happy giggle that warmed the hearts of the other people in the room.
Their parents thought it was adorable.
Even more so when they started babbling to one another, Katsuki using more complex babbles but Izuku would still raise his hands in happiness with each insult like sound.
Even smiling and showing his toothless smile that made the angry babbling stop, being replaced by a funny giggle. Weird, since Katsuki almost never giggles, unless one of his parents had hurt themselves by mistake.
It was adorable in a way, but oh the things they were saying weren't nice.
Once words were added to their skill set, everybody could understand what they had been saying for a long time even if their babbles were only understood within each other.
“Your mom still does that thing” Katsuki said rather loudly.
“Shoosh! She can hear you!” Izuku shushed his friend.
“Right. Sorry” Inko decides to ignore her gut for a second, they're only two years old, nothing to worry about.
A couple minutes go by, Izuku is chasing Katsuki and they're giggling. She decides to go for some more snacks since her kids already finished the apple slices she brought.
“See! She's doing it again!”
“She worries about our tummy's Kacchan!”
“My mom has been bugging me about not eating dinner when I'm back Zuzu! You know how annoying she is”
Her Izuku rolls his eyes and tackles Katsuki to the floor, they roll around for a couple of minutes but Inko doesn't want to continue making the little flower sandwiches she was making after hearing Katsuki. Maybe she does feed them a lot?
“Mmh. Maybe you should tell her? Mom says I have to play a lot or I'll get fat”
“What's wrong with being fat?”
“Well— Huh? You're right”
And they continue chasing each other.
Of course Inko brings the issue to the Bakugou's, afraid of Katsuki developing an eating disorder if his parents talk like that about food. But they reassure her that their talks are more oriented about how Mitsuki is finding it a lot harder than she expected to go back to modeling since giving birth.
Inko should have realised then, kept insisting maybe.
Those fleeting moments that she decided to ignore could have made a difference, she didn't do it back then and by the time she decided to intervene it had been too late to actually change how her boy was behaving..
.
Kacchan laughs loudly, Izuku giggles and his little tummy does a funny turn that obscures the guilty feeling for saying Tsubasa runs quite funny.
“He does!” Kacchan shouts after he stopped laughing, snorting some little more when Izuku can't stop his giggles.
“He's trying his best though” he smiles, his mommy has been saying to be nicer, since she's seen how Kacchan and him behave when their parents aren't around.
“Why don't we drop them?” the blonde asks. They're watching the rest of the kids in their neighborhood running around, playing tag. Kacchan and him refused to play, preferring to climb the monkey bars.
“That's not nice Kacchan” Izuku mumbles, his mommy's words still on his mind. Kacchan sighs dramatically, hanging upside down from the bars.
“You're sooooo boring” Kacchan grumbles, looking upside down to the other kids.
“B— but, we could umh… go to the forest?”
“And do what?” the blonde grumbles, he likes the forest and capturing bugs but they did that yesterday.
“And kiss?” Kacchan looks at him with a small smirk, slowly turning upwards.
They have been talking about doing that, after hearing Kacchan's parents say that it's normal for people that love each other. In Izuku's mind, that loves, adores and breathes Kacchan it means they should do it.
“Not chickenin’ out now?” Kacchan smirks, sharp and mocking, making Izuku's tummy do that funny turn again.
“Nope!” Izuku smiles with all teeth, nodding with excitement.
“Nah! I don't believe you!” Kacchan taunts him.
“I will!” Izuku sets his ground and Kacchan seems to believe him, getting off the monkey bars and looking at him.
“Let's go then!”
Izuku gets down with some difficulties, Kacchan waits patiently for him to get down. The greenette has noticed that more and more lately, he's as clumsy as their other friends, nobody has the amount of skills Kacchan does so everybody else is clumsy compared to him, but the blonde only laughs and calls the others out.
Well— more like he does it harshly and with Izuku he does it nicely? He doesn't really know how to explain. With them it's mean teasing, the kind that is supposed to make the other kid teary eyed. But with Izuku it's supposed to make him laugh and tease Kacchan back.
He likes it.
“Took you long enough” Kacchan says, faking boredom.
“We aren't all half monkeys like you” Izuku pulls out his tongue in a meanie gesture.
“Oi!” but the blonde is laughing, amused, instead of actually offended, ruffling his hair.
“Wanna race?” Izuku asks, because he knows Kacchan loves competitions, even if they're worthless like this one.
“Ya!”
They get into position, waiting for the blonde signal to start the race when the other group of kids come closer, asking for their attention.
“Where are you going?”
“I wanna play too!”
“Can we play?”
“Ugh” Kacchan stands up straight looking at them with those fiery eyes of his that usually mean ‘leave alone’ except for Izuku, for the greenette means ‘come closer’.
“Sorry, this is just for smart enough boys” Izuku interrupts their requests with a bright smile before taking Kacchan's hand and starting to run.
“Ah! Wait—” and Kacchan begins to giggle, soon enough stopping to follow Izuku and taking the lead, he’s now pulling his slow best friend, both laughing without any care.
The others are following behind them, not really understanding Izuku's comment. So Kacchan does a rather aggressive pull, changing their trajectory to a well known part of the forest where the other kids got lost last time.
Izuku has to cover his mouth to stop his laughs from giving them away. While being dragged away, they end up in a weird looking cave that they discovered casually last week, it’s perfect to hide from those dummies.
Kacchan pushes him to the wall rather harshly with a smirk on his face. Oh. He's gonna do something.
“You're so ugly” whispered Kacchan in that teasing way, he wants to rail Izuku up, to make him get as mean as Katsuki. Izuku shows him his tongue, Kacchan gasps as if he had insulted his mother instead.
“Kacchan must have terrible taste for wanting to kiss me, then” he whispers with a matching
teasing smirk to that of Katsuki.
“My taste is impeccable!” the blonde boy puffs his chest, putting his hands on his hips in a proud stance.
“In… inpecca— inpecca” Izuku is more interested in trying to expand his vocabulary as fast as Kacchan.
“So dumb…” the older kid rolls his eyes, pinching his friends cheek “My taste is the best”
“I'm the best?” Izuku takes the unintentional compliment with bright eyes, always thirsty for Kacchan’s compliments.
“Shaddup” Kacchan pouts, Izuku giggles at his friends' antiques.
They stay in silence for a while, just looking at each other. Izuku loves to do that, to attentively watch those red eyes that sometimes shine with the sun so bright it leaves his tummy doing those weird things he likes.
Then he feels it, a light touch on his lips, from Kacchan’s lips. His whole face is burning red in a few seconds. Kacchan’s loud laugh is what gives them away to the rest of the neighborhood kids but neither feels like it was a bad thing.
Izuku really liked how soft Kacchan lips are and Katsuki loved the face of admiration Izuku gifted him with.
.
Izuku got his quirkless diagnosis. And yet they were still as inseparable as always.
They're painting with their fingers today, Kacchan making a green ball that Izuku thinks may be him and Izuku is making All Might, like always.
“Oh fuck” he was giving the last details to his All Might drawing when he heard Kacchan curse. Izuku understands that his best friend hears his mom curse a lot, but Izuku’s own mommy has said that those are grown up words and that little, innocent kids like him should not be saying anything like that.
“Kacchan!” so of course he scolds him anytime he hears him say one.
“Sorry! It's just— look” Kacchan points to Ichiyo, a boy whose quirk is to to grow plants from his hands, he can't even control them, he just makes them grow, his drawing looks like himself in a stereotypical hero costume.
“Oh” the green boy doesn’t understand why is Katsuki even paying attention to somebody else if Kacchan’s inspiration is right besides him “Poor boy” he whispers after thinking about it. Knowing how it feels to have an impossible dream.
“He thinks he can be a hero with that lame ass quirk” Kacchan practically growls with venom.
“But Kacchan! You said anyone can be a hero” Izuku turns to look at him with an intense look, determination and a little hurt reflecting on his eyes.
“Yeah, anyone smart enough” the blonde huffs, understanding why Izuku is suddenly so defensive, he disarms him easily by putting green paint on his little nose “He eats glue” Izuku giggles at the unintentional praise. Kacchan thinks Izuku is smart!
“Don't kill his dreams Kacchan” the greenette mutters in that tone he’s seen aunt Mitsuki use when she doesn’t mean something but wants Inko to be happy. Katsuki snorts, reading the tone.
“He will get himself killed anyway”
Izuku doesn't know why that's one of the funniest things he's ever heard, so he laughs out loud, they both get scolded for disrupting the peace of the classroom.
Neither one regrets it.
They prefer each other anyway. Or at least Izuku does, he can spend the whole day with Kacchan and he will never be bored. They’re playing hand games as quietly as possible so as to not be reprimanded again, Kacchan wins most of the games but the greenette doesn’t feel the need to tell him to be fair and let him win once when the blonde takes his hands, interlocking their fingers together.
“But real talk ‘Zuku. You’re so much better than any of them. We’ll be the greatest heroes of all time”
Izuku nods. He believes anything that Kacchan has to say, he’s always right after all, and when he isn’t, Izuku can just pretend he is.
.
Recess was fun that day, lots of games and activities with the rest of their classmates, at least until Yuka came by giving Kacchan a pink envelope, with a heart as the seal.
She said to open it in private, but there's nothing he doesn't share with Izuku so he just opened it in front of him.
It was a love letter.
Rather embarrassing in Izuku's opinion with way too many compliments that were only referring to Kacchan's physical appearance, no sign about his smarts or even his extremely powerful quirk, nothing.
Izuku hummed after reading it. He had wished to laugh at such bad writing and even worse compliments, eyes like strawberries? That's the best she can do? But he couldn't just do that in case Kacchan did like it.
He would vomit if Kacchan liked it.
Kacchan groaned, taking the letter and making it into a paper ball before throwing it to the garbage, of course it hit the target, at first try.
“Kacchan's amazing!” Izuku complimented right away, but the blonde wasn't looking at him, he was looking at Yuka with irritation.
“This would stop if you were my boyfriend” Kacchan tells him as soon as they're already back in the classroom.
Izuku trips with his own foot, too shocked by what he just heard Kacchan say to actually pay attention to the floor. The blonde doesn't let him fall, putting his arm in front of the greenette to stop Izuku from touching the floor.
“You ok?”
“Yes! S—sorry Kacchan!” The blonde looks at him with a smirk, oh he was just messing with him! “Kacchan mean!” So he hits him on the arm.
His best friend laughs out loud, but it's not his mean laugh, it's his ‘I’m gonna enjoy seeing you squirm’ kinda laugh.
“So? You wanna be my boyfriend or not?” and now the blonde is all over his personal space, with his arm around Izuku, pulling him to their seats. It makes him dizzy, Kacchan always smells sweet after playing, it kinda makes Izuku hungry.
“I uh…” the boy whispers. He knows boyfriends and girlfriends are a step away from marriage, his mommy said so, and she did say to be careful with who he chooses to be with. In his eyes there's no better option than Kacchan, but in Kacchan eyes? There has to be someone better, right?
“Why are you so red? It's not like we haven't kissed before” Kacchan whispers before sitting him on his usual seat, shoving Toshito away from the seat at Izuku's side so he can sit there.
“Don't say it too loudly!” the greenette whimpers, covering his hot face.
“Aw, is little Izuku ashamed of kissing me?” Kacchan sounds taunting but Izuku knows better, he is hiding how he feels with mean comments.
“No! Nonono— I’d never— I really like Kacchan's kisses” so the greenette tells him right away, moving his hands from side to side in hopes of making Kacchan realise how serious he is.
“Then, ‘Zuku? You don't want to?” the blonde pressed again, he really wants Izuku to be his boyfriend.
“I— but what if Kacchan wants a girlfriend late—” in his mind, that's just how it is, they're the best of friends, always there for each other, then Katsuki gets a girlfriend and then a wife, they have kids and Izuku can be the funny uncle. He didn't realise this was even an option!
“You gotta be kidding me” the blonde moves away, taking his hand, forcing him to turn towards him “I'm not interested in girls. They're so annoying. I'm just interested in you”
“Me?”
“Yah. My partner. My best friend. My Izuku” and that made him shiver, his whole body vibrating from the mere implication of belonging to Kacchan.
“But— young” his mommy did say that he wouldn't have to worry about girlfriends until he was at least fifteen, so he's a little worried.
“We ain't that young. Twelve seems like a reasonable age for me” Kacchan rolls his eyes, taking his hand in his, making soothing motions with his thumb on Izuku's hand.
“Oh Kacchan” and yeah, he's lost this little battle, because there's nothing more he wants than Kacchan.
“Just tell me you don't like me so we can move on” Katsuki chuckles, it's painfully fake. He tries to let go of his hand.
“No! I actually really like you…” but Izuku won't let him.
“Oh? Then be my boyfriend” and there's that smirk again.
And Izuku laughs a short defeated laugh, he was imagining a beautiful confession in either of their rooms, with flowers or at least some snacks, not this… But Kacchan has always been a direct person.
There's no confession that could be more Kacchan like than this one.
“I'd love to be your boyfriend, Kacchan”
“Sweet”
That day they both went running to Katsuki's house, since Inko was going to be working until the night, holding hands and giggling all the way till they were in front of the intimidating house that belongs to the Bakugou’s.
They ate with a smile, kissing each other mid bites and still chewing, tasting the different versions of curry Mitsuki made with each kiss, Kacchan's was a lot spicier than his. But that won't stop Izuku from kissing his brand new boyfriend.
After they were done with homework, and played some minutes to Bakugou's hero agency, they were laying down on the blondes bed. Izuku had died tragically as the villain that wanted to dominate the world. And Kacchan died after killing the villain because of his bad injuries.
It's the first time their game ended in a draw.
“Hey… ‘Zuku” the blonde moves to look at his face.
“Yes, Kacchan?” Izuku asks with a tiny smile.
“I love your eyes” he begins, making Izuku's whole face light up, looking like a strawberry “They're so big, round and green. Like the forest, I like the forest a lot”
And Izuku has no idea what to say, he never expected Kacchan to get so… sentimental.
“Uh… thanks? I— I really love your eyes too! They're so red. Like cherries, completely sweet and—” he stops talking, he feels a mumbling attack about to come out and he doesn't want to annoy Kacchan.
“And?”
“What are we doing?” the greenette asks instead, covering his face up to try and stop Katsuki from staring at his face any more.
“My parents do this before sleeping. I thought it was a good idea. You don't like it?”
“I do” and he gets lost in those beautiful vermilion eyes. “I love it a lot”
He really likes being Kacchan's boyfriend.
.
He’s watching Kacchan playing basketball from the stands, since their P.E. teacher didn’t take their little talks criticizing their classmates and the really terrible way of throwing the ball at the basket too kindly. So she took Izuku out of the game, telling him to just sit in the stands and watch.
Izuku isn’t too bothered by it. He enjoys watching Kacchan play, it allows him to watch Kacchan carefully without feeling his whole face get red because of all of the attention he is receiving from his boyfriend. What does bother him is that it is always him.
Always.
Adults are afraid of tarnishing Kacchan’s reputation and therefore his chances to get into UA if they actually do punish him. So Izuku bears the weight of their endeavours. He sighs in annoyance when he sees how happy Kariage looks playing with Kacchan, it’s so obvious the black haired boy has a crush on Izuku’s boyfriend. He’s so annoying.
And then Yoshiru falls down on his face. The whole game pauses for a second before Katsuki laughs loudly, his laugh always makes Izuku laugh but he’s trying to behave so their teacher lets him go back to play alongside his boyfriend, which is why he only covers his mouth while muffling his small giggles.
He feels his gaze before even turning, Kacchan is looking at him with a bright smile, as if looking for his approval in the shape of Izuku’s laughter. The greenette only gives a small smile that makes Katsuki roll his eyes and show him his tongue. Izuku does the same even if it’s from a distance.
They snort at the same time and his tummy does that same motion it has been doing since he was little. He’s so down badly for him, isn’t he?
The teacher decides to stop the game and let them do whatever they want for the rest of the class. In their case, that means sitting side by side while talking about their classmates and why most of them will end up with a grave injury if they do choose to get into heroics.
“Laira could make it, but she’s a little too much into not looking dumb. She won’t get better if she doesn’t try to get better, even if it means looking a little dumb once in a while” Izuku, like always, takes these conversations seriously. After all, if he doesn’t make it into UA and he goes the analysing route he needs to take little things like this seriously.
“You would know about looking dumb, won’t you?” Kacchan teases with a smile on his face, his eyes tinkling with memories of them, of what Izuku can only guess has to do with thursday's nights and Izuku choking around his boyfriends dick.
“Kacchan is such a pervert, can’t even focus in our conversation”
Katsuki scoffs, flicking him on the nose before giving him a kiss on the cheek.
“Fine. I’ll tell you what I think. First, Hinto. He has a lot of potential, making air poisonous is kind of badass, but the way he can’t control it makes him more of a liability than anything. Ohiro has a great shape and resistance but he’s so fucking clumsy, like how can you not keep the ball with you? Are your hands just for decoration? And don’t get me started on Yoshiru. Did you see how his own foot made him trip? What kind of stupid—” but he’s interrupted by Izuku who also wants to talk about what he’s seen and to be honest what’s bothering him for a while now.
“Kacchan! Ha! At least he tried. Didn’t you see how Kariage was only watching you? Drooling like a stupid mutt?” He makes a disgusted face that makes Katsuki laugh again, hugging his boyfriend by the back of the neck.
Oh how he loves to make his boyfriend laugh.
“You jealous or something?” Katsuki taunts, kissing his cheek before making his kisses go down, straight to the neck.
“Of course I am. Kacchan’s mine. No other bitch should take him from me” Izuku mumbles, a little distracted by such pleasing kisses, normally he would be panting and moaning just by the feeling of those lips against his skin but he doesn’t have the freedom of being as loud as he wants with the rest of his classmates around.
“Shuddap. You ain’t a bitch” Katsuki looks at his eyes with rage, as if he was insulting himself and Katsuki was having none of it “You’re my wife” his eyes melted in a gaze full of love and Izuku just had to take his excitement out on a brief scream.
“Kacchaaaaan” he shakes his forehead against his boyfriends sweaty one, he never minds having a sweaty Kacchan on top of him. “I’m not a girl though” the greenette pouts after saying that.
“So?” Katsuki bites his cheek, both angry at Izuku for insulting himself earlier and as a way to release the aggression his beautiful green eyes give him.
“Ouch! Kacchan!” the boy massaged his cheek to try and make the pain go away.
“Kacchan, Kacchan Kacchan. Doncha ever shut up?” his boyfriend rolls his eyes before settling against the structure, it’s a little uncomfortable but he can bear it.
“Just when you kiss me” Izuku pouts, he wants a kiss, mostly because PDA makes people stop looking at Katsuki.
“Disgusting” and yet he kisses him with a need he makes Izuku blush “My beautiful Zuzu”
They can hear the murmurs of the rest of the class, always such greedy creatures for gossip and what better gossip than the clingy boyfriends of their class. Even more so when they don’t refrain from saying out loud how they feel about the rest of their classmates. Izuku is pretty sure he saw Kariage smirking when they were talking about him.
“But I don’t like how he looks at you” the greenette brings up the topic again, Kacchan won’t judge him, laugh and point and even mock maybe, but never judge.
“What can I do to make it better?” Izuku gasps, Kacchan never does anything that someone else tells him to do, so the fact that he’s asking Izuku what he wants him to do is making his insides turn. He just loves Katsuki a lot.
“I don’t know” he murmurs, feeling him so close he wants to kiss him again. Unfortunately their teacher tells them to go to the showers.
They were walking side by side when Katsuki held his hand, a shy smile in Izuku’s mouth made the blonde snort before talking again “Break some bones?”
There’s a few gasps and Izuku’s shy smile turns sharp, he wants to show off how much Katsuki loves him so that he is ready to be violent to him.
Like in elementary school, where the blonde would stand up for him whenever someone heard the comments Izuku would say to make Kacchan laugh and try to hit him for being such a rude boy, that and the lack of a quirk used to make him an easy target for both his own enemies and Kacchan’s.
“Noooo. Kacchan needs a clean record, remember?” Izuku sighs, it’s unfair. He wants Katsuki to defend him, he wants Katsuki to be violent, to be himself. But he has to calm him or he could hurt both their futures.
“Could be an accident” the blonde mumbles, not playfully, serious, probably already remembering the routine of extra 1 in his mind to better see where said accident could happen.
Izuku laughs. Adoring the focused look on his boyfriend's face.
“Yeah, that could work”
A week later, Kariage is found on the road, 10 meters from Aldera Middle School, still breathing but in extreme pain, three broken ribs, a broken leg and a hard concussion. The paramedics were called to the scene fast, called by a blonde classmate who was worried for their supposed friend when the boy took longer than usual on getting to school.
It was clearly an accident and yet you could hear the murmurs talking about how Kacchan is more of a villain than a hero. Kacchan would scoff and say that he didn’t care but he knows better. Or Izuku would like to think so, because Kacchan is not an omnipotent presence, he has the limitations of any other kid their age, and he never takes that route to get to school, they even made it to school together!
Even if a tiny part of Izuku wishes to believe it was indeed Kacchan’s fault and he did it because of him, because he was bothering Izuku.
He can only hope.
They pull out their bentos, it’s Izuku’s turn to make for both of them. Katsuki isn’t the biggest fan of his cooking, it’s always a little too undercooked, but he understands that’s probably because of how Auntie Inko herself cooks, always with time on top of her, so he never utters his complaints.
“It’s too hard, again” Izuku mumbles after eating his rice, the rice cooker did said it had four minutes more to go but he unfortunately had to leave at that exact moment or he’ll be late “I’m sorry Kacchan”
“It’s good”
“It’s so not”
Katsuki snorts, it’s horrible but Izuku made it. He’ll eat it, even if he gets a stomachache later.
They eat mostly in silence since the whole classroom is in silence, paying their respects to Kariage. Izuku did say the boy wasn’t dead, only in the hospital but they marked him as not empathetic enough on his general file and told him to shut up.
He is definitely not getting into U.A. now. Which is why he can hear the murmurs as clear as if they were talking right in front of him. Everyone keeps saying it was Bakugou’s fault, that he must have pushed the boy into traffic. Impossible, Katsuki was waiting for him at his house wearing an incredibly angry scowl because they had to run to try and get to school in time.
“Maybe he hired someone”
“With what money? He’s fifteen”
“His parents are rich though”
No, Kacchan uses his money on better things, gym equipment, nutritious foods, All Might figures for Izuku or himself, expensive places where Izuku really wanted to go. Things like that. His boyfriend has no money to spare.
“Uh… Kacchan” Izuku whispers low, he's sure Kacchan doesn't mind if he talks but the greenette is a little afraid his boyfriend will begin to believe them.
“I really don’t care” the blonde says after another bite of not so cooked rice. “As long as you’re with me” he finishes with a smirk.
Izuku swayed his feet with a smile on his lips.
“I love you, Kacchan”
.
He’s walking towards his class when he’s hit by a shoulder rather harshly, making him step back two steps to avoid falling. Kacchan is already in their classroom, so he has to be more alert, since people think that picking up on him when he’s alone is easier than when they’re together.
“Watch yourself, quirkless bitch”
Those words register faster than who said them, making his gaze raise, looking at the guy who crashed against him. Kariage and Mirisho. Huh.
“Oh, I thought you were still in the hospital” The words may have been uttered by Mirisho, but Kariage was at his side completely silent, no longer trailing after Izuku’s boyfriend as a lost puppy.
“Mind your fucking bussiness” Mirisho answers with barely disguised rage, in this game, the first one to get angry is the first one to lose.
“He’s your bodyguard now? Too scared to even walk the street alone, right?” so he ignores the teen.
“You bit—”
“I would shut up if I was you. I’m interested in seeing how much does your eyes extend” normally, this is where Kacchan makes his tiny explosions and they take the hint.
The problem is he doesn’t have a quirk to even threaten them with. But he does have a pair of scissors he isn't afraid to pull out if needed. So he does, showing only the scissor’s handle with a sweet smile, the type of smile he gives to his mother when he wants to sleep at Kacchan’s.
The two other teens tense, which made him smile even harder, he didn’t think it would work. They backed off, walking faster towards the cafeteria, walking side by side as if afraid to be the one closer to Izuku and get stabbed. He giggles, it’s cute. Izuku only dreamed about things like this since he isn’t particularly intimidating.
At last, he got to the classroom, his drink and Kacchan’s in hand. His boyfriend smiles at him, hitting his lap, telling him to sit there.
So, here they are. Izuku is feeding Kacchan some small bite-sized sausages while the greenette is sitting on his lap. The position allows them to talk closely without being heard by their classmates and that’s a sweet relief for Izuku and his tarnished record. He loves to trashtalk with Kacchan and make him laugh with harsh comments about anything but he can’t allow any more marks on his records.
“You ever think about how useless Mishiro's quirk is?” the greenette looks up at him, resting his head on Kacchan’s shoulder. His boyfriend gives him a peck.
“Who’s that?” of course the blonde doesn’t know their classmates' names.
“Eyes guy”
“Ah, yeah. A good knife and he’s done for” Katsuki answers, opening his mouth, asking for more food.
“Right? He speaks too much for being so vulnerable” and Izuku feeds him.
.
Izuku is not a good student. Scratch that, he's not a conventionally good student. He’s smart, yeah. And he learns quickly, he isn’t the second best student in their class for nothing, but his note taking is trash. He’s always too endorsed on his own analysis, writing about his boyfriend and how he is training or All Might or any other hero he had seen before getting to school.
So forgive him if he didn’t hear a thing about a new guy in school.
Shunzi Satoru, coming to Aldera for his last middle school year.
If Izuku had paid attention, he may have seen him before gym class, in a quirk practice day. If Izuku had paid attention, he may have seen the twinkle of admiration in his eyes when Katsuki was practicing his more focused explosions.
If Izuku had paid attention, he would have seen the clear disgust on his eyes when Izuku goes straight to the stands because he doesn't have a quirk to practice with.
“Hey Bakugou. We’ll be going to the arcade that’s around the corner, wanna come?”
Izuku stopped writing, the last sentence of the analysis he was making about how maybe Kacchan needs to use his own hand to be more precise since he is immune to his own quirk, he looks up. A new pair of eyes he had never seen focused on his boyfriend, he reads him quickly. Admiration, interest… attraction. Nope, no. Stop.
“Nah. I’m busy” Kacchan answers immediately, not even looking at the new blue eyes, he is busy looking at Izuku, he notices at last how those vermillion eyes are looking at him with so much affection, while he was writing about Kacchan.
He giggles, feeling his face warm up.
“With what?” the new boy interrupts their moment. Izuku feels that impulse of telling him to shut up, but he has nothing on him. It’s dangerous to attack without knowing your enemy in depth.
“Star gazing” Kacchan answers again, not letting his gaze go away from Izuku, he even cups his cheek, caressing his freckles with his thumb.
And oh my All Might! He’s gonna die, he feels his heart going faster. So fast— ah! Kacchan can’t just be this sweet without a warning!
“Maybe strawberry picking” Katsuki smirks, seeing those rosy cheeks turn red like strawberries.
“Aaaah Kacchaaaaan” Izuku covers his face. Too flustered to talk correctly.
“Lame” blue eyes says and it ruins the mood so fast he feels extremely bad. His boyfriend took the time to flirt with him! That's just disrespectful!
“The fuck is your problem?” Kacchan asks with the same amount of disrespect.
“Maybe you should be more interested in what people of your caliber can do” the blue eyed teen tells him and Izuku has been teased since he was a child for being quirkless, such a comment shouldn't sting. Except it does, because he knows Kacchan deserves better.
“Maybe you should mind your fucking business, asshole”
And that's when Izuku found his own toy.
The first thing he does is something simple that will allow him to see how Shunzi reacts, violent, apologetic, embarrassed? He was confident and violent with people backing him up, but once that company leaves, how does he act?
Izuku trips him in the morning. Acting as if he was yawning with his whole body, the boy trips and uses some chairs to not hit the floor. His eyes look angry and like he wants to hit him, but he just glares.
He’s one of those, huh.
So it begins his ride to bother the boy as much as he can.
.
Kacchan is playing cards with his friends while Izuku is writing on his notebook, almost completely laying on top of the blonde. It was a peaceful day in the classroom, with a teacher that only gave one assignment and decided that they could do whatever they wanted to do.
He hears snickering, so Izuku raises his gaze to watch over the classroom, his eyes focusing on black hair and blue eyes. Ah, right. Him. So Izuku hears more closely, it’s a bit difficult when you have a blonde boyfriend screaming at his friends about being cheaters or sore losers.
“He must be stupid since he is dating a quirkless”
And yeah, he’s taking advantage of their school’s dislike for Izuku to make friends. He stands up after reading the chapter he’s been writing on the boy, Katsuki’s eyes following Izuku, always attentive to his boyfriend, Izuku smiles at him before moving his hand, telling him not to worry.
He’s walking towards the classroom’s door slowly, going over what he wrote mentally, the teen’s quirk is quite useless, changing the color of things with a touch of his fingers, not much resistance and average strength. Nothing he couldn’t take on his own, so he sees this as a little opportunity. If he takes on one member of that stupid little gang, the comments about Kacchan will cease.
Izuku isn’t an idiot, so when he sees a foot trying to trip him he steps on it, making Kimoni scream in pain, which, rude. Izuku is not that heavy!
“Oh. Sorry” he says with the least amount of worry he can master, it does look like it's bending quite wrong.
“You bit—” but he bites his own lip, not letting what he was about to say be heard.
“Zuzu? Where you going?” Kacchan is hugging his waist, looking at the funny leg with a smirk after finally winning at cards.
“Mmh? Restroom” Izuku answers with a sweet smile.
“You're so boring” that Kacchan manages to make disappear in seconds.
“Well— excuse me for having to pee”
Katsuki rolls his eyes and pushes him towards the door, Izuku glares for a second before moving to exit the room.
The greenette hears footsteps leaving the class once he's about to turn to the right, on his way to the restroom. He would be lying if he said this isn't exactly what he wanted, it'd be especially perfect if the stalker was Shunzi, but no matter who it is, Izuku has to strike first.
He makes it to the restroom, going to wash his hands to make time for his poorly disguised follower to reach him.
The other person is behind him, Izuku can feel their presence. A challenge maybe, but he takes no time. Kacchan says that if he’s going to give the first hit it has to be the best hit, so he closes his fist, and quickly hits the person on the nose.
It cracks, he feels bad about it almost immediately.
“Ouch! What the—” ah it is Shunzi. Perfect.
“You were too close to me!” and so it begins his trial to be declared innocent when he's obviously guilty.
There's a heated back and forth that makes teachers appear, he is trying hard not to laugh at his own shitty excuses but they aren't working since they love to gang up on him. He really wishes to stop being dependent on Kacchan but guess today isn't the day.
He lets the tears fall down his cheeks and sobs once.
The blonde that was staying outside the commotion takes that as his cue to appear.
“What's going on here?” He asks with concern, Izuku can't say if it's fake or not.
The teachers tell him to leave, but he's the son of Mitsuki Bakugou and so he begins to fight with the teachers too. It's honestly impressive to see Katsuki, using so many of his own accomplishments to fight for Izuku's rights.
At the end, they conceive in favour of Izuku. Leaving with a teen who has his nose broken and a broken hurt look on his eyes. Maybe they should have brought him to the hospital first instead of doing this whole discussion.
A pair of minutes pass by where Izuku is trying to wash off some of the blood from his shoes.
“You broke his nose!” Kacchan says way too excited now that they're alone and decompressing. Hugging him from behind and moving him from side to side.
“I know! I didn’t mean it!” Izuku is so close to crying for real, this time because of the really hurt look the poor boy gave him after being scolded and suspended, those guilty feelings he’s felt since he was little appearing again. But Kacchan turns him, still between his arms, kissing his temple, laughing, telling him everything will be okay and Izuku always believes him.
.
Izuku knows he should be nicer. He promised his mommy he will, it was the only condition she gave him to allow him to be a hero. That he had to be the good boy she raised and not the mean one Kacchan loves. But oh god if some of his classmates at U.A. are plain stupid.
“No, Kaminari” he smiles because otherwise he will be showing how much he wants to strangle him and force the knowledge to enter his mind by force “It’s the exact opposite to functions— You know what? Let’s take a break” Izuku sighs, getting up from the couch in the living room.
“See? Told you it was easier to teach a horse to talk than them how to do integrals” Kacchan tells him as soon as he enters the kitchen, his boyfriend was watching him enthusiastically try to teach the blonde’s friends some calculus, with a sharp smile, adoring how Izuku's eye was twitching while his smile got weaker.
“I wanted a challenge” he sighed, wanting to be comforted by big arms around him. Katsuki complied, as any good boyfriend should.
“Some challenges aren't worth it, baby” Kacchan kisses his temple, making Izuku smile.
“That's quitter talk” he teases him anyway.
“Oi! I ain't a quitter!” the blonde pushes the greenette away with his hand, making him hit the kitchen aisle while laughing.
“They're just so dumb” Izuku whispers, trying not to be heard.
“I know” Katsuki sighs, he has an effect on idiots that they always wanna be friends with him.
“And they take everything so literally” Izuku continues, remembering when he said to Ashido she needed to switch the numbers and she did it to every single number on the equation.
“It exasperates me too” Katsuki sighs, remembering his own teaching attempts and how they ended with Katsuki having to go blow something up.
“Like pleeeeease, use your common sense” Izuku exaggerates his tone, making his boyfriend smile in his cruel way.
“A lot of people here don’t have it” Kacchan closes his eyes.
Izuku nods, looking at his boyfriend's vermillion eyes with a tiny smile. He really likes to complain about other people with him.
For a second he remembers Todoroki and how he stares at them whenever they show some PDA around the common room.
“Like Todoroki. You would think the son of a recognised hero has common sense though” he didn't mean to say it out loud.
“It must have been beaten out of him” Kacchan answers, it was automatic, the same way it's been since kindergarten.
Izuku chokes on his own spit, before being able to laugh, hitting Kacchan on the chest.
“That's so mean!”
“Then why you laughing like an ugly hyena?” Kacchan tries to stop the hits by holding his wrists.
“Because you made me mean!”
“You sound like your mom” and he shows him his tongue, like when they were kids.
“Whatever…” Izuku pouts, crossing his arms, looking at Kacchan's friends still complaining about math.
“Also the purple molester. That guy keeps asking me how sex feels like” Katsuki releases his wrist, making a disgusted expression.
“Yuck” Izuku fakes a gag, making Katsuki laugh.
“He's so weird”
“Like maybe he would get a date if he stops being himself”
“With his height?” The greenette laughs again, this time louder and unafraid, that was less mean.
“I think I was his height at 8” Izuku adds.
Kacchan snorted, giving him a little kiss, sneaking his hands into Izuku's pants and giving a light squeeze.
“Hurry up and teach them so I can teach you how to bounce”
.
“You'd think a war would've made you more empathetic”
“It just made me even more pissed off at people. Why are they making their problems my problem too?” Katsuki mumbles getting into Izuku's hospital bed.
He used his good hand to pull Izuku into his bad arm, hiding his face from artificial lights in soft green curls, breathing in peace.
Izuku doesn't move, doesn't do anything but breathe and enjoys his boyfriend's presence. He still can't process that his Kacchan was dead for at least some minutes, he refuses to acknowledge it until something forces him to do it.
“Zuzu” Izuku opens his eyes, not noticing he had closed them and looks to his right where Katsuki's bandaged chest is on the view.
“Yes, Kacchan?”
“I got killed by a fucking League player” his boyfriend says it with such anger Izuku can't help but giggle even if his ribs hurts and he probably shouldn't be moving his body like that.
“Lame ass ending for a lame ass kid” Izuku replies, moving to see his boyfriend face to face, careful to not hurt himself in the process.
“Oh you wish I was lame” Kacchan replied, letting go of Izuku so he could move.
“But you are. You go to sleep at 9 o'clock!” Izuku replies, nuzzling his boyfriend's chest.
“Not my fault you have shitty sleeping habits” Katsuki kisses his curls, mourning the ones that were shaved off.
“You should stay awake at least ‘til 10. So I can kiss you for an hour” Izuku replies and for a moment everything is silent and peaceful and warm and he can't be more grateful for this right here.
“I hope the purple molester didn't survive”
“Kacchan!” And like their routine, he acts scandalised for a second before breaking into loud laughs.
He can feel the disappointment radiating off All Might. A shame he doesn't have the energy to keep his friendly and kind persona up, even if what happened with Shigaraki made it less of a persona and more of his actual personality.
Kacchan does bring out the best and the worst of him.
.
“I’m such a whiny bitch now” his boyfriend complains letting the hand gripper slip from his hand, Izuku takes it in his hands, feeling so guilty about seeing his boyfriend struggling.
“You came back from the dead, Kacchan. It’s okay”
Kacchan only glared at him, holding his hand up for Izuku to put the hand gripper in it, trying once again to close it completely. He fails once again and decides to throw it towards the floor with strength. Izuku gasps, quickly picking it up to see if it was badly damaged.
“Calm down Kacchan!” the greenette complaints, looking it over, it's completely fine which actually makes him feel bad. It means Kacchan doesn't have enough strength yet and he knows it's his fault.
“Shaddup!... I should be stronger” he groans, sitting down on one of the sofas in the therapy room. He lets his head fall on the back of the sofa, looking uncomfortable.
“Maybe you should sit down upright?”
“It's not the—! It's just… I'm the strongest one of us… I should— protect you”
“That's not true Kacchan. I can protect you too”
“And look how that turned out” Katsuki mumbles with resentment. Izuku knows he doesn't mean it, that his boyfriend just becomes mean and angry when he can't do something.
And yet his eyes began to look wet, tears falling down easily. He tries to dry them quickly and reply with a mocking sharp comment too. But it doesn't come, instead he sobs, it's small but it makes Kacchan turn at such a speed Izuku swear he heard his neck crack.
Katsuki moved fast, standing from the sofa and getting closer to his boyfriend, cupping his face with such tenderness he sobs again. And the blonde is drying his tears carefully.
“I'm sorry. I'm really fucking sorry. I didn't mean it, baby” he's apologising faster than Izuku has ever heard him.
It's weird since whenever Izuku cries he would have gotten annoyed, just patting his head, mumbling some apologies. So now, being treated with such love?
“Kacchaaaaan” he sobs harder, hiding his face in his boyfriend's neck. Katsuki kisses his hair, while muzzling his face on those green curls, hugging his waist as much as he can with a hand that still can't apply much force.
“I'm sorry, baby” the blonde begins to move backwards, taking his boyfriend with him to the sofa, slowly.
“You're so mean!” Izuku sobs on his neck.
“I know” Katsuki sits, his boyfriend sitting on his lap immediately.
“Mean Kacchan!” and that makes Katsuki smile, he sounds like always, so the blonde chuckles, giving his boyfriend a little peck.
“Kacchan's sorry” Katsuki mumbles against his lips.
“Kacchan loves me?” and Izuku asks, just to be sure, just to hear it clearly.
“Kacchan loves you so much” Kacchan delivers exactly like how Izuku wanted him to.
That's when Katsuki noticed for the first time how they've changed. There's still love, there will always be, but it's more honest, less hidden.
He loves this kind of love.
.
“Fucking press always on the way” Katsuki mumbles with an angry scowl while trying to move between the reporters and some civillians that managed to get in.
“Right!? I get being excited to get the news first but they were in the way!” Izuku rolls his eyes at a camera that is still trailing after him before snickering and smiling at it, the public loves when he does that, they think he’s imitating Kacchan.
“Fuckers getting in trouble and then we gotta take care of ‘em and their troubles” Katsuki mumbles angrily, opening the door towards their agency. THEIRS as in, they have an agency together!! like they promised to! Izuku still thinks it’s a dream come true.
“Such unnecessary work” Izuku answers, starting to walk backwards to look at his husband's face. He is just that handsome, he wants to see his gorgeous face all the time!
“Still shit talking, huh?” Sero teases while they are walking towards their combined office. A few months after opening their agency their friends decided to also join. It was annoying at times, like this moment since Hanta will take away the sole focus that Kacchan had on him.
“It ain’t our fault y’all just assumed Zuzu is nice” Katsuki answers mockingly while taking his boyfriend's arm and making him almost trip to get Izuku into his arms.
“He was so adorable! All nervous and shy!”
“He was probably thinking how to beat you in a fight”
“He would never” he would and he did numerous times, even analysing how Kacchan could beat them all up, he was bored!
“He totally would” Ochako tries to defend him in a weird way, coming from the other side of the hallway with her incredibly sweet smile “He’s as much of an asshole as Bakugou”
“He has mellowed down tho” Shouto gives his input at her side.
“I would say both have mellowed down!” Kirishima comes out of his own office, as if this was an improvised reunion in the common room like the ones they used to have before.
So Katsuki rolls his eyes, takes his boyfriend up and leaves directly to their room. He wants to enjoy his husband, the one made specifically for him. Izuku, like him, wants to get to their office and ride his husband to de-scalate their adrenaline from the recent patrol they did.
Unfortunately for them, they did not get very far, since both of them got absolutely assaulted by their friends wanting to talk with them.
Maybe later at home. After a round of sparring of course.
