Two years ago, Dazai met his bestfriend and now boyfriend, Chuuya Nakahara at fourteen years old. Now sixteen, the two were inseparable to the point that Osamu was unofficially living with Chuuya in the shorter teen's penthouse. Most nights, he stayed with Chuuya, but he still spent enough time at his shipping container to be considered living on his own to an extent.

He would love to stay with the ginger full-time, but, well... he was hiding something from the other. Osamu Dazai has narcolepsy. Being such a.. vulnerable condition, he didn't let anybody know about this fact. One, he hates vulnerability, and two, how would people look at him in they knew The Black Wraith of the Port Mafia had narcolepsy?? Because of this, the only person who knows is his technical legal guardian and doctor, Mori Ougai.

He was medicated, so it was easier to hide, but it didn't change the fact that he had it. For the past two years, he's been doing a good job hiding it somehow, but of course, he wouldn't be able to hide it forever, considering sleep attacks him both at random or when he gets too excited or stressed.

Last night, he hadn't gotten good sleep, so it was already a disaster waiting to happen, but they didn't have any important work today, so the two were staying at Chuuya's place today, and Osamu figured he'd be fine. Well, everything was, in fact, not fine, because the two were playing video games, and Osamu was on a winning streak. After his fifth victory, Chuuya was getting pissed, and Osamu being himself, had to celebrate! So, he stood up, started bragging and doing a victory dance to piss the ginger off more.... then everything went black.

Chuuya doesn't know what the hell happened. One moment, the taller teen was rubbing his defeat in his face, and the next, his eyes were rolling back and he was on the ground. With wide eyes, Chuuya was by the brunette's side in an instant, shaking him as he called his name. "Osamu?? Osamu!!"

After a full minute, Osamu grunts and his eyes flutter open, Chuuya sighing in relief. "Oi, Mackerel, are you okay? You just passed out... are you sick?? Why didn't you tell me?"
