Remember: everything Dazai Osamu says is made up.

Chuuya was normally talking to Mori about some missions not even noticing his malicious looks to the male, soon Chuuya saw Dazai get on the room and simply ignored him while continuing to go on with what was on the mission, but that was when he felt Dazai embrace him from behind and put his head onto Chuuya’s shoulder “Chibi aren’t we doing something tonight? Why must you stay with this garbage of a boss?”
