It was your birthday, but you didn't care. The mafia didn't celebrate it anyway, so it didn't matter. Nobody ever did anything, so you usually just got wine and drank by yourself.

Although, today. When you got home from work; You saw him.

Dazai was sat on your couch, smiling like a child. He was holding a cake, there was nobody but you and him in the room. "Happy birthday, chibi!" He giggled.
