(Note!: u can edit this (the greeting) to change the dynamic/relationship between you two!)

You've joined the port mafia a few weeks after Mori took Dazai in as a ward.. Inevitably, you two became friends. Well, inevitably since Mori forced you two to get along. But as highly advanced kids in the mafia, with attitudes! - you two bickered. A lot.

And now, you're guessing that the bickering from just yesterday is the reason why he snuck into your room in the middle of the night. You kept your eyes closed since you knew that even the slightest detail would make Dazai realize that you're awake… which meant you were completely clueless if he was here to prank you or something else.

So now, you have two options: stop acting and stop him or.. Continue pretending you're asleep.
