Unexpected Turn of Events

Summary:

The brunette ignored him and finished wrapping himself up, getting dressed in the borrowed clothing. “Finished!” Dazai announced, crawling on the large bed. He stopped right at the beginning of the redheads nest and sat down on his haunches. Chuuya peaked over his shoulder and gave the other teen a confused look. “Mori-san said that I can’t just go into an omegas nest without their permission. It’ll make the omega upset or something.”

Chuuya rolled his eyes, sitting himself up “Whatever. Get in already.” The bed shifted with the weight from Dazai moving. He crawled into Chuuyas nest slowly, like he was nervous about disrupting it even though earlier he did such a thing. Dazai pressed his shoulder against Chuuya's, granting him a soft sigh from the other. Chuuya automatically nuzzled his face into the crook of Dazai’s neck, “Don’t say anythin’.”

--------

Finding out his secondary gender is omega. Chuuya has to deal with his first heat and unlucky for him, Dazai also discovered he's an alpha.

Notes:

For a mutual of mine on twitter who wanted to see more sfw omegaverse fics!

I took a lot of liberties on a/b/o and how first heats work. so i hope everyone enjoys these two navigating their feelings.

(See the end of the work for more notes.)

Work Text:

The words he didn’t expect to hear continued to echo in his mind. 

 

“You’re an omega.” Mori said in such a casual tone that made Chuuya’s skin prickle. 

 

He was requested by the boss to speak to him in his private office in regards to another matter, but Mori mentioned that both Chuuya and Dazai were at the age to present as their secondary gender and offered to check for Chuuya since the boy was already there. The process was quick and the results were available as quickly as Mori pricked his finger for a small blood sample. Chuuya didn’t know what to expect, the odds were either for or against him. Honestly, the redhead was hoping to be a beta. It would have been at least some normality in his life that he deserved. 

 

Chuuya stared down at the cheesy little pamphlet in his hand. Why would a mafia boss even have these at the ready was baffling in itself, he knew Mori was a doctor prior to taking over; but even then this seemed extremely silly and childish for someone like him to have on his person. Still he read it front to back, letting out a groan. Everything was overwhelming him. Things like, heats, ruts, mating, nesting, and bonding marks? He roughly folded the pamphlet in half and shoved it into one of the front pockets of his pants. With that he shoved both his hands into his pockets and walked rather quickly towards the elevator that led to Mori’s office on the upper floor. 

 

He stopped in front of it as the doors slid open revealing a familiar body inside with messy brown hair. Chuuya scoffed as Dazai crossed by him with one of his stupid know-it-all smirks on his face as he passed by. As he entered the elevator he watched as Dazai entered Mori’s office, catching him peek over his shoulder before the door shut. 



Months went by before Chuuya was unfortunate to be in the beginnings of his heat. After that meeting with Mori and finding out about his secondary gender, he did more research into it and discovered the more, well, uncomfortable parts of being an omega.

 

 A male omega at that. 

 

Things the young boy wished he didn’t have to know about. Everything just made his skin crawl as he “enlightened” himself on what to basically expect during an omegas heat. More overwhelming information was going through his head and Chuuya despised every minute of it. 

 

Thankfully being under Kouyou’s charge gave him slight comfort knowing the older woman was willing to look out for him during his first heat. Unlike Chuuya, she wasn’t an omega but an alpha; but the older redhead did have experience taking care of other omegas during their heats , especially first timers. Kouyou did explain to him that it’s easier at a younger age and possible to spend it alone as long as he was properly scented by an alpha. Though she highly recommended that he would find a trusted alpha to stick with him for the time being. As he got older and towards sexual maturity, that would all change and he would need something called a heat partner . He didn’t want to hear anymore after that. 

 

Chuuya grimaced as he felt a cramp creep up on him as he was shopping. He knew he looked awful, Chuuya could feel feverish on top of the random stomach cramps constantly coming and going. Not to mention the overwhelming smells that surrounded him, everyone's pheromones felt like a personal attack against his nose. Because of that the boy was powering through the early symptoms trying to prepare before his heat fully hit and that was in less than two days according to Kouyou. He still needed to stock up on easy to eat foods and water bottles for the next five days.

 

Five. Whole. Days. 

 

The redheaded boy clicked his tongue as he piled snacks on top of the cups of ramen he decided on. The basket started to weigh down on his arm, but that was quickly remedied with his ability. As he turned down another aisle where there were chips of many flavors and types lined up he spotted none other than Dazai standing in front of the row. Chuuya rolled his eyes and promptly ignored the brunette before the idiot opened his big mouth. 

 

“That all can’t be good for you.” Dazai gave him a toothy grin. 

 

“I didn’t ask your opinion, asshole.” 

 

The other boy merely hummed and grabbed a random bag of chips and faced Chuuya. He dropped the bag in the basket ignoring Chuuya’s protest. Dazai merely leaned in closer to the other teen, “Wow Chuuya, your face is really flushed! You must be starting your heat pretty soon, right?” Chuuya’s free fist curled up tightly and he swung at Dazai who stepped backwards avoiding the shorter boy. “If your smell didn’t give it away, your reaction sure did!” He laughed before grabbing yet another bag of chips and tossing it into Chuuya’s basket. 

 

“Stop puttin’ these nasty flavors in here!” Chuuya shouted, “I don’t recall tellin’ your ass anythin’ about all of that and it’s none of your business, mackerel!” He took the last bag Dazai threw out of the basket and placed it back where it belonged. Chuuya rushed past the brunette and made his way to the register, only to hear the clicking of Dazai’s shoes behind him. He ignored Dazai to the best of his ability as he roughly placed the basket on top of the conveyor belt. 

 

Once he paid for everything, he took out the gross flavor of chips and shoved them at Dazai, “Here.” The brunette looked at him questioningly as he wrapped his hand around the bag. 

 

“What a good dog, feeding his master.” 

 

Oh how he wanted to punch that stupid look off of Dazai’s face, “I don’t have time to deal with you.”  He turned away from the teen and began his walk back to the Port Mafia building. Chuuya huffed as he caught Dazai walking beside from the corner of his eye. “I don’t recall wantin’ your company.” He bit out. 

 

“I have something to do there like Chuuya.” Dazai merely smiled. Chuuya sighed and shook his head. The two of them walked side by side until they arrived at the large black building. They entered with ease, the armed grunts standing inside ignored the two as they made their way deeper inside of the building. Dazai continued to follow Chuuya until the shorter of the two spotted Kouyou waiting for him. 

 

“Lad.” Kouyou waved Chuuya over to where she was sitting alone. The teen gave a side glance at Dazai who was already heading to the double panel elevator. He walked up to the older redhead and plopped down in the open seat next to her, letting the bag hit the floor and a sigh of relief as his body finally got a moment to fully relax. Kouyou looked at the bag by his foot and made a face, “I said easy to eat foods, not junk.” 

 

“It’s stuff I -like-, ane-san. If I’m spending five days trapped in my apartment I want it to be somewhat enjoyable.”

 

The woman gave him an understanding smile and twisted her body to grab a large plain brown bag that was sitting on the table next to her. She passed it over to Chuuya who took it without any questions and peeked inside. Inside of the bag were a few blankets of different colors and textures, “What’s this for ane-san?” He set the bag next to his own and looked over at Kouyou. 

 

“You’ll need them for your nest.” She said matter of factly. Chuuya groaned, he forgot about that. Well no, almost like he purposely skimmed over it because nesting just sounded unlike him. It made him think he was a bird or something. His bed was fine as it was, but apparently it wouldn’t be enough for him to be fully comfortable during his heat. “I know it’s a lot to take in, Chuuya.” Kouyou placed a kind hand on his shoulder, “You’re still okay with me helping you out for it, if not I can find another alpha to help you with it.” 

 

Chuuya shook his head, “I rather it be you ane-san, I trust you.” Chuckling, “and you actually have a nice smell that I can deal with for those days.” He gave the older woman a small smile. Kouyou gently pushed his shoulder and leaned back on the soft back of the couch. 

 

“Very well. I’ll be over to your apartment the day after tomorrow. Make sure you get bottled water before you lock yourself in. You’ll be surprised how much you sweat.” He gave her a curt nod and gathered the bags by his feet before standing up. With a small bow Chuuya left the Port Mafia building and headed to his lone apartment. 



As expected his body felt worse than it did a few days ago, the cramps came harder and faster than before. Every bit of his skin felt inflamed from this fever that wouldn’t go away despite his attempts at taking pain relief to subdue it. 

 

His heat was officially in full affect and Chuuya felt miserable.

 

After taking a long soak in his tub the young boy dressed himself in comfortable clothing, his choker long gone since it felt extremely tight around his neck. Chuuya let out a sigh as he sat down on his bed, the towel he used to dry off was slung over his shoulders. Chuuya’s bed looked like an unkept mess, there were blankets from Kouyou and his own piled up on one half of his bed, on top of his pillows were all placed exactly how they should be. It gave him an odd sense of comfort seeing it like that. He took the fluffy towel and started drying his hair as fast as he could. Kouyou was expected to arrive at his apartment any minute now. When he deemed it dry enough, the towel was tossed into a nearby hamper. 

 

An uncharacteristically rapid knock came from the front door. He tilted his head at it, but forced himself from the comfort of his bed and made his way to the front. Chuuya already knew it had to be Kouyou, so he didn’t bother checking the intercom and opened the door, “Ane-san you’re ea—” He stopped mid sentence when realizing it was not the older woman in front of him, rather the one person he did not want to see. Dazai stood in front of Chuuya holding what looked like a lumpy duffle bag in one hand and a plastic bag from one of the convenience stores around the apartment complex. “What the hell are you doing here?” 

 

“Ane-san said she couldn’t make it. Mori-san sent her off on a last minute job!” Dazai chirped out too excitedly. 

 

Chuuya scowled and started to shut the door on the other teen, but Dazai was quick and rushed his way inside of Chuuya’s apartment while kicking his shoes off at the front.  

 

“Okay, but why are you here? If ane-san couldn’t make it she would have sent another alpha, not your dumbass.” The redhead snapped, slamming his door closed.  

 

“Oh, I’m an alpha.” Dazai stated, like it was a fact that Chuuya should have already known, “That’s why I had something to do at the office the other day.” 

 

This wasn’t happening. It was like the universe was fully against Chuuya today. He glared at the other teen as Dazai half heartedly tossed his things on the couch. The black coat was long abandoned on the floor. Chuuya clicked his tongue and snatched the worn out thing from the floor and laid it neatly on the arm of the couch.  He looked over at Dazai who was already digging through the duffle bag, pulling things out. Soon there was a pile of games and what looked like Dazai’s own blanket and pillow, on top of rolls of bandages. 

 

“Wait. Why are you unpackin’?” 

 

Dazai stopped what he was doing and scoffed at the other teen, “I didn’t expect my dog to be so stupid.” He let out an exaggerated sigh, “I’m here to spend the next five days out of the kindness of my heart to help my dear Chuuya with his heat.” 

 

The brunette smiled at the visible irritation that quickly shifted to confusion on Chuuya’s face. He continued, “You do know that you have to spend the entire time with an alpha in your nest, right?” Chuuya knew, Kouyou made it extremely clear that he had the option during his first few heats to spend them without an alpha, but for Dazai to willing himself into this situation. It was weirdly suspicious of him. 

 

 Dazai hummed and went back to taking out the rest of the junk from his bag. He picked up the blanket and pillow, “Your nest is in your room, right?” He turned and started walking the short hallway towards the other boy’s room. Chuuya stammered and quickly went after Dazai. The two boys both walked into the redheads room. Dazai circled the bed and cocked his head, “It’s not what I expected.” He muttered to himself as he dropped the pillow and blanket he dropped carelessly in the nest.

 

Chuuya shot him a glare and snatched up the two items and sorted them out correctly. Though, honestly Chuuya didn’t fully understand either, the books spoke of nesting behaviors but never really went into full details of how they were supposed to look like. He just went with his gut, what his omega felt was needed to make the so-called ‘perfect’ nest. His musings were interrupted by Dazai grabbing the blankets that were given to him by Kouyou. 

 

“Hey! What do you think you’re doin’, mackerel?” 

 

“These are from ane-san, right? I can smell her.” He said as he sloppily folded the baby pink blanket and then did the same to a crisp white one, “Mori-san said that if there’s another alpha’s scent it can cause a problem.” The brunette gave it a small sniff, “Ane-san has a pleasant scent. It reminds me of when you’d walk by a florist.” Dazai placed the bundle on the floor away from the bed, “Chuuya, on the other hand surprisingly doesn’t smell like a dog.” 

 

“Yeah, the same can be said about you.” Chuuya grumbled. Dazai’s scent was an interesting mix of leather and bergamot. Each time the other boy would merely move his body, he would catch his scent and it was extremely soothing. Without even realizing it, his body wasn’t fighting with him. Chuuya felt calm and almost normal while Dazai was in the room. With a sigh, “Alright.” 

 

“Hm?” 

 

“You can stay and…help me with this.” He motioned towards the nest and then at himself. Dazai had a big almost stupidlike grin across his face, instantly making Chuuya feel like he made the wrong choice. Not like he had a choice, it was getting later by the minute and the cramps were weighing down on him. He desperately wanted to crawl into his nest and just curl up into a ball. “Before you even think about getting in there with me, take a shower and put on your pajamas or whatever you brought.” 

 

“I didn’t bring any.” 

 

“Huh?” Chuuya pinched the bridge of his nose, “But you remembered to bring useless shit like bandages. Just—-Borrow some of mine.” 

 

“Ew! I don’t wanna wear slug clothes! Dazai whined, “ And why do I need to shower, it’s not like we’re going to have sex.” An exaggerated gasp left the boys lips, “Unless that’s what Chuuya is plan—“

 

“I’m not letting you into my nest in those nasty clothes! Top drawer!” Flustered by even the thought of seeing the other boy nude. Chuuya yelled before Dazai could finish the rest of his sentence. The brunette pouted and shuffled towards the large dresser and pulled out a shirt and shorts from where the other boy told him. 

 

“Are these even going to fit me?” Growling, he ignored the stupid question and roughly shoved Dazai towards his connected bathroom and slammed the door behind him. 

 

The gravity user covered his mouth and groaned.

 

Nausea. 

 

It lasted a few moments before the teen shook his head. He peered at the bathroom door and listened to the water running before returning to the living room to gather the things Dazai brought. Chuuya stared at the pile and smirked at the miscellaneous things  before gathering the items up and putting them back in the duffle bag Dazai brought. He grabbed it by the handles and the convenience store bag and took it into the bedroom. Dropping the bags on the opposite side of the bed, Chuuya circled and crawled directly into his nest. He sighed, closing his eyes and started to nuzzle his face into the pillow Dazai brought, feeling a rumble in his chest.

 

His eyes snapped wide open and immediately felt grossed out by his actions. Chuuya rolled onto his back and stared at the plain white ceiling above him. “There’s no way I can do this for the rest of my life.” He muttered quietly to himself, knowing that it only got worse from now on. At least Mori was willing to provide him the medication, or suppressants as he called them, to limit how often the boy would have to deal with his heat. It made sense, losing out on a valuable ability user even for more than a day would cause a possible issue. 



The sounds from the bathroom quickly alerted him that Dazai was finished. Chuuya rolled on his side and faced the bathroom door in anticipation of the brunette. The door cracked open and Chuuya caught Dazai peeking out. 

 

“I don’t have my bandages.” Dazai said with a pout in his voice, “Chuuya needs to look away so I can get them.” 

 

Chuuya rolled his eyes and instead of closing them, he rolled on his other side facing the large window. He could see Dazai’s reflection as the other teen hastily walked out of the bathroom only wearing a towel over his waist. The clothes he took out of Chuuya’s drawers were bundled up close to his chest. Dazai stopped by the bed, seeing his bag on it. He started rummaging through it again and pulled out a roll of new bandages. The towel fell as he started wrapping himself up. Chuuya quickly curled his face into the pillow, “You dumbass! Do that in the bathroom!” His shout came out muffled thanks to the pillow. 

 

The brunette ignored him and finished wrapping himself up, getting dressed in the borrowed clothing. “Finished!” Dazai announced, crawling on the large bed. He stopped right at the beginning of the redheads nest and sat down on his haunches. Chuuya peaked over his shoulder and gave the other teen a confused look. “Mori-san said that I can’t just go into an omegas nest without their permission. It’ll make the omega upset or something.” 

 

Chuuya rolled his eyes, sitting himself up “Whatever. Get in already.” The bed shifted with the weight from Dazai moving. He crawled into Chuuyas nest slowly, like he was nervous about disrupting it even though earlier he did such a thing. Dazai pressed his shoulder against Chuuya's, granting him a soft sigh from the other. Chuuya automatically nuzzled his face into the crook of Dazai’s neck, “Don’t say anythin’.” 

 

The two of them sat in almost silence. There was a strange noise coming from Dazai as the redhead practically tried to burrow himself in Dazai’s neck, much to his embarrassment and disgust at wanting to be literally on top of the other boy. The noise would get louder as Chuuya shifted his body around trying to find the perfect position, but it was making it hard for Chuuya to relax. 

 

“Why do you keep doing that?” 

 

“Doing what, slug?” Dazai asked. 

 

“That weird noise.” 

 

Chuuya felt Dazai shrug, “Iunno.” The brunette reached over for his bag and pulled it closer to himself, “Chuuya keeps making a weird sound too. Almost like a cat purring.” The other teen jerked his head out from the confines of Dazai’s neck and scowled at the other boy for a split second. Of course he forgot about it, the stupid purring when omegas are comfortable with their alpha. Dazai had already taken out his hand held and booted up a game that was already inside it, “Didn’t Chuuya’s books tell him?”

 

The redhead sighed, “Yeah. Only about omega things that I need to know about, not shitty alphas and their weird things. Didn’t Mori-san explain anything else?” 

 

There was a slight tint of pink on Dazai’s cheeks, he kept his unbandaged eye focused on the rapid changing lights on the hand held screen. “Some stuff.” He mumbled out. It was obvious that Dazai was uncomfortable. Something Chuuya rarely if ever saw the boy have any other expressions besides his cocky, know it all smirks he always has. 

 

“Oh yeah? Like what.” 

 

Dazai shifted his body, turning it away from Chuuya. His face was showing more red now. Was it really that bad? From Chuuya’s understanding alphas go through ruts once a month, much like an omegas heat. While his rough knowledge of alpha heats was very limited to what he read in his own books, he couldn’t see why Dazai was uncomfortable.

 

“If it’s about your ruts, I already know about those.” Chuuya said with a roll of his eyes. 

 

“Not that.” The brunette huffed and rolled over completely, facing away from Chuuya. “Mori-san said that during sex my..” He muttered under his breath. The other teen completely hovered over Dazai and leaned in closely. When Dazai finally mumbled out what he was so embarrassed about. Chuuya instantly punched the boy in the arm and fell backwards into his half the nest. 

 

“I’m going through cramps and nausea because my guts are rearranging themselves for a permanent uterus of all things and you’re embarrassed because your dick does something weird only during sex.” There was bitterness in his voice. Chuuya wished that it was temporary, in fact he wished he didn’t have to experience this at all. He watched as Dazai rubbed his arm where he was punched. Although Chuuya didn’t hit Dazai as hard as he would have normally done, he did still feel a little guilty. They were both going through a weird change in their lives, on top of everything else that was expected and required of them as members of Port Mafia. 

 

“Sorry.”

 

Dazai let out a soft hum as acknowledgement. The hand held was long abandoned,  recklessly tossed by the boy’s things with a game over screen glaring on it. He sat himself back up to Chuuya’s level, looking at him deadpan, “I’m hungry.” The gravity user’s lips quicked into a half smirk and sunk in further into the nest. 

 

Chuuya was also feeling hungry now that he wasn’t feeling bad with Dazai’s scent lingering around him, but he also didn’t want to get up and make anything nor make the other boy fetch him something to eat. He remembered the convenience store bag that Dazai brought with him, “Isn’t there something to eat in that bag?” Chuuya motioned towards said bag. 

 

“Ehhh, but I want Chuuya to make me something!” The teen playfully whined, “It’s the least he could do since I have to touch him and get his slug scent on me!” 

 

Instead of arguing with Dazai and picking more fights the two settled on ordering out, all at Chuuya's expense since Dazai lacked any extra allowance money from Mori after buying another game. They spent the next few days in Chuuya’s nest and once the feeling of dread stopped lingering over the redhead, they moved over into the living room to stretch their bodies and to watch movies or some random show on the large TV. It felt like a normal sleepover to Chuuya, minus when he would catch himself nuzzling into the junction on Dazai’s neck where he later learned was where one of their scent glands existed on their bodies. He stopped fighting his instincts all together and just let it happen. The purring noises and whatever thing Dazai did was soothing to his, for lack of a better word, omega. Chuuya was able to doze on and off while Dazai just sat next to him playing whatever game. 

 

By the fourth day Chuuya was feeling grimey. He wanted a shower and a quick soak in his tub, but they found out the hard way the other day if Dazai and him separated for too long. The boy would essentially have a panic inwardly as soon as Dazai would step away. It was yet another thing Chuuya was aware of, but didn’t think it would have affected him that strongly. 

 

Dazai was busying himself eating a bag of shrimp chips that Chuuya was helping himself to before stating the very obvious, “We need to take a shower.” Dazai cocked his head at the omega and bit down on one of the chips in his hands. 

 

“How? Chuuya smells like the beach and since I’m constantly touching you, I smell the same.” 

 

“No. If I feel gross and sweaty then you’re probably the same. We need to take a shower and I want to soak in my tub.” 

 

Dazais' brows furrowed at Chuuya, “Then take one slug. You don’t need my permission.” Bitting out as he ate more of his snacks. Chuuya clicked his tongue and snatched the bag out of the boy's hands. 

 

“We’re takin’ one together.” He gritted out, grabbing Dazai by the collar of his borrowed shirt. Chuuya didn’t care he was stretching it out as Dazai flailed around like a child trying to get out of Chuuya’s tight grip. “If you’re worried about me seein’ you without your stupid bandages keep them on for all I care.” He yanked the boy and forced him out of the nest. Dazai stumbled at the sudden jerk of his body and the unevenness from transitioning out of the nest to the hardwood flooring. 

 

Dazai continued his whining, “I don’t understand why Chuuya is making me bathe with him! It’s weird!” It wasn’t weird per say, a lot of boys their age would take baths together at public ones, but still Chuuya never thought in a million years he would be forcing the other teen into taking a bath with him. His bathroom was big enough for the two of them to stay separated at a reasonable distance without causing the redhead’s omega to go into a panic. 

 

The bathroom door swung open and Chuuya along with Dazai both entered the room. The omega let go of Dazai and started undressing. Four days of being almost on top of each other gave Chuuya no reason to be shy about getting nude in front of Dazai. It felt wonderful to finally peel his shirt off of his body, he quickly removed his shorts and paused at his underwear. Chuuya stared at Dazai who was standing there awkwardly, avoiding the redheads glare. 

 

“If you shower and let me soak peacefully, I’ll order whatever you want for dinner.” 



Chuuya hummed a happy tune as he left the bathroom first. He felt so, so, so much better afterwards. He shut the door behind him, giving Dazai a chance to finish up while he got dressed. There was still a few days left of his heat so he opted for comfortable clothes again. The bathroom door opened with a crack and he saw Dazai peering out from it. Chuuya sighed and rolled his eyes. 

 

“What do you want to eat?” 

 

“Pizza.”

 

“Okay.” Chuuya circled to the nightstand that had his cellphone charging. “What kind?”

 

“Seafood.” 

 

The redhead sighed and nodded his head before turning his back on Dazai, allowing him to leave the bathroom to gather clothes and bandages. 

 

Food arrived and two boys decided to eat in the living room. Piled on top of a few of Chuuya’s things from his nest, they settled on the couch and ate their food while watching whatever was on the TV. “Hey.” Chuuya said between bites, “Are you going to be willing to do this with me until the Boss puts me on suppressants?” 

 

Dazai gave him a toothy grin, “So my little puppy likes my scent that much.~” How much he wished he could punch his stupid face flashed through Chuuya’s mind. “I–I don’t mind it. I’m having fun with Chuuya.” The brunette mumbled out with a slight tinge of pink on his cheeks, “Just this though. I don’t wanna get gross sex germs from you.” 

 

“Likewise.” The redhead said annoyed. 




The fifth and final day came and went just as fast as the other days. Chuuya woke up from the nest and sat up feeling extremely refreshed. He looked over at the sleeping form of the other boy next to him. Giving his dry lips a small lick almost nervously, he leaned down and brushed his cheek against Dazai’s. Chuuya sighed as he inhaled the alpha’s scent before backing away and sliding out of the messy nest. He grabbed his phone, gave it a quick check to see if he received any messages from Mori or Kouyou before pocketing it. 

 

Chuuya looked around the room and his bed and grimaced at the mess everywhere. Snack bags, food containers, empty water bottles, and Dazai’s things were thrown everywhere. In any normal circumstances he would have never allowed his room to get this bad, but circumstances weren’t normal for the gravity user. He quietly left the bedroom in search of trash bags to start cleaning the mess. Before starting Chuuya rummaged through his kitchen and made a small breakfast for himself and ensured he had enough ingredients leftover to make Dazai something if he was hungry. After spending almost a whole week eating junk and takeout, the semi-homemade breakfast tasted like it was the best thing he had eaten. 

 

Dishes were washed and the kitchen was also tidied up. Thankfully they hardly used it so Chuuya didn’t have to spend much time there. The living room also didn’t look too bad either, despite them spending half of Chuuya’s heat in it. Taking advantage of his ability he was able to also tidy his living room up before finally making it to the bedroom. 

 

Dazai was still asleep. 

 

“Hmm.” 

 

Quietly as possible Chuuya started picking up the trash around the bedroom floor and on the bed. As soon as he finished that, he used his ability to carry the bags out of the room and into the little area where the shoes sat between the front door and the living room itself and left them there to be taken out later on. The teen returned to his room again and saw Dazai stirring, he ignored him for the time being and picked up both his own clothes, including the ones Dazai borrowed the first few days and Dazai’s own clothes. They were placed inside of the hamper and Chuuya carried it out to wash. 

 

Once he finished with that the boy lingered in the living room and sat down on the plush couch letting out a sigh. Chuuya felt a soft vibration from his pocket and fished his phone out, he flipped it open and answered it with a short and curt, “Hello.” On the other line was the older redhead ability user.

 

Chuuya, how are you feeling? I feel awful I was not able to help you through your first heat, but Mori-dono insisted I take a mission. 

 

Oh. Ane-san, I’m fine. It wasn’t too bad thanks to shitty Dazai.

 

Dazai? Well that’s a surprise, I didn’t know he presented as an alpha. 

 

Mm. Neither did I, but y’know how he is.

 

A soft giggle was heard on the other end. They went back and forth for a while until Chuuya caught Dazai walking out into the living room with a sleepy dazed look. He sat down next to Chuuya and laid his head on the redhead’s shoulder. Chuuya adjusted himself to let Dazai get more comfortable and continued his conversation with the older woman. The call ended with a snap of the phone closing. 

 

“Your stuff is in the washer.” Chuuya tossed his phone on the glass plane coffee table in front of them, “When they’re finished you can go home or whatever. My heat is pretty much over.” Dazai didn’t say anything but Chuuya could feel him nodding on his shoulder. It was a little awkward now, having Dazai so close to his body. 

 

Almost unwanted now. 

 

Back to how things were between the two teens. Chuuya shrugged his shoulders, giving Dazai the hint to get off of him now. He got up and went to the room where his washer and dryer were and switched out the laundry. It would be another thirty or so minutes before everything was dry and Dazai would finally be out of his hair for the time being, at least until Mori put them on a mission together or—

 

Would he have to be there for Dazai’s ruts now? He had both hands on the dryer and leaned forward. That thought never really crossed his mind until now, it would only be fair for him to help Dazai out; but were ruts before sexual maturity just like heats? Where the alpha needs an omega to just essentially cuddle with them for a week, or did they actually require sex? 

 

Even with his omega instincts the thought of doing more than what they did this week with Dazai made him feel gross. He made a mental note to ask Kouyou the next time he saw her at the mafias building when he returned to work about that. The heat from the dryer on his hands snapped Chuuya back out of his thoughts and he left the room. 

 

Dazai wasn’t in the living room when he came back. He did hear rustling from the bedroom so he walked into it and saw Dazai picking up his things and shoving it sloppily into the bag. Chuuya watched him as he reached over for the blanket he brought and pulled it out of Chuuya’s nest. He quickly grabbed it from the brunette before he had a chance to shove it into the bag. 

 

“Leave it.” He growled. 

 

The other boy raised an eyebrow questioning but chose not to fight with Chuuya. Even if he said he was finished with his heat, there were still the lingering effects he would have to continue to deal with. Dazai let go of the blanket, letting Chuuya fold it neatly and placing it down on the bed. He continued packing everything up and zipped the lumpy duffle bag up and pulled it off of the bed with a grunt. 

 

“Is Chuuya really finished? I thought you were going to bite me if I took my things back!” Dazai swung the bag around and sighed dramatically as he left the bedroom. Chuuya ignored the others' antics and followed behind him. 



The laundry was finished and Dazai went to change out of Chuuya’s clothes. The redhead was busy making a fast lunch for the two of them before Dazai officially left. The boy re-entered the living room dressed in his typical white button up and black slacks that he came over in; and padded over into the kitchen. Taking a seat on the tall stools that sat in front of the bar that separated the kitchen and living room. Chuuya served the alpha a simple omurice that he learned how to make a few weeks ago. He sat down next to Dazai and they ate in silence as usual. 

 

“It’s good.” Dazai said softly. 

 

“Thanks.” 

 

“Slug is surprisingly handy. He’ll make a good wife someday.” 

 

Chuuya kicked his leg under the bar, shutting the other boy up.



Weeks after Dazai left the apartment felt larger than normal. Chuuya was standing outside on the balcony, dressed in clothes he had worked out in prior, one of the shirts Dazai had borrowed during their week on him and a cigarette dangling between his lips. A new habit he picked up after a stressful mission he was put on after returning to work. He was thankful Mori didn’t hesitate to put him back to work as soon as his heat was over. Chuuya didn’t want to be viewed as weak and incapable of doing his job just because of his status as an omega. He inhaled the smoke and exhaled a few times before the smoldering embers on the filer only remained. 

 

The redhead smothered it out in the ashtray lingering on the steel railing and pulled at the collar of the shirt. Even through the smells of smoke and Chuuya’s laundry soap, he could still smell the soft scent of leather and bergamot from the alpha. Sighing softly as he inhaled the lingering smell he felt his face get warm. 

 

“Damnit.”
