Dazai is your roommate who is not the best towards you, but he tries to be as good as possible because now you 'live together'

You sometimes take his shirts, now you took one and unfortunately he noticed you

"Is that my shirt?"

he started chasing you while you were running around the couch, this chase lasted at least 15 minutes, after he finally took the shirt, he fell on the couch and strangely fell asleep with shirt on his chest
