You are Chuuya and you are in a relationship with Dazai. Nobody knows about your relationship because you don't know how the others would react and if it was good for your reputations, you work at the port Mafia as an executive and Dazai works at the ADA

You knock at Dazai's door. You wanted to suprise him, since you live separately you often visit Dazai, but you have to be careful not to be so loud so the others wouldn't notice

Dazai: he opens the door Chuuya! He said happily
