Summary
Working as a server at a high-end restaurant in Kabukicho means that life isn't always as uninteresting as Oikawa hopes it might be. But the job pays well, his manager is understanding of his university schedule, and Oikawa takes pride in being able to meet some of Japan's most prominent businessmen even if he doesn't really care for what they do.
That is, until Iwaizumi Hajime takes an interest in him.

Summary
Iwaizumi barks out a laugh. “I’m still trying to get over the fact that you made a PowerPoint presentation about why we should date.”
Oikawa doesn’t tell him the file has existed for the last twelve years, constantly receives updates, and that the original copy contained almost a hundred slides before he forced himself to get a grip.
Moments in Oikawa’s journey to win over his best friend’s love: the sad, the happy, and everything in between.- Language:

Summary
In which Iwaizumi Hajime is a junior doctor suffering through his medical rotation, and Dr. Oikawa Tooru is his insufferable mentor. Medical AU.
‘I heard your internal medicine rotation’s going to be at Miyagi Central Hospital,' Suga says, turning to Iwaizumi. 'Who’s your mentor gonna be?’
‘Dr. Oikawa Tooru,’ Iwaizumi replies, and barely has time to yank his body back as Suga chokes on and almost sprays out a mouthful of alcohol.
‘What is it,’ Iwaizumi says, feeling a little unnerved.
In response, Suga simply drags a pitcher of alcohol from across the table, and starts to tip more beer into Iwaizumi’s glass. ‘You’re going to need this,’ Suga says.

Summary
He takes a step closer to Iwaizumi and says, “You’re going to have to pry this gym away from my cold, dead hands if you really want it, Iwa-chan.”
Iwaizumi leans in and grins without any humor. “Bring it on, pretty boy.”
Or, five-ish times that Oikawa Tooru has the grave misfortune of encountering the very annoying hot asshole of a baseball captain.

Summary
"Appearance wise, Iwaizumi Hajime was eighteen years old. In actuality, he was a little over five-hundred years old. No, he wasn't a vampire. No, he wasn't a vampire/alpha hybrid, or whatever the hell that was. Quite simply, Iwaizumi Hajime was cursed."
