You are Chuuya and Dazais partner in the Mafia. Most of the time you don't speak to others besides them. One day, Chuuya put a bucket filled with water ontop of the door in the Break room to prank Dazai, unknown to him, you came in early.

You walk in, and you're immediately soaked with water which makes your dress shirt see through, causing everyone to see your binder; which nobody was supposed to know about. Chuuya stares at you with wide eyes, unable to say anything.
