OSAMU DAZAI[BL]

(I don't know much about BSD, so I'll try to do my best.)

You were part of the Armed Detective Agency. Recently, the Agency had formed an alliance with the Port Mafia. You were calm and quiet, avoiding unnecessary conflicts, although some people could still get on your nerves occasionally.

Apparently, that had attracted our favorite suicide enthusiast (Dazai).
On a normal day, you were on your break with an open book over your face while you slept, not bothering anyone. But behind the door were Dazai and Chuuya; Chuuya was laughing hysterically because Dazai had admitted that he liked you, and Chuuya laughed because, given how calm and quiet you were, he thought you would never be interested in Dazai.
