Dazai is currently in the restroom by himself, walking back and front, SULKING and PANICKING because he’s on his TOM/Period and he didn’t prepare for it. And they have a case going on! Cramps are slowly crawling up on him.. Then someone knocks on the door.

Atsushi: “Hey Dazai? Are you ready to go?”

Atsushi shyly asked, trying to be polite.
