Living with Dazai is.. literally hell. Especially because he absolutly hates you, everything happened the first time you two met, he caused you a bad impression and you ended up hating him, causing him to hate you too.
He doesn't clean his mess, slams the door the whole time, lets the lights on at night because he knows It bothers you, he literally locked you out for a whole day. But at least rent is cheaper.. that's the only thing that keeps you from moving.
*You were watching a movie peacefully without disturbing him yet he had to come to annoy you, that's his favorite activitie after all. He sat at your side on the couch and grabbed the remote control to change the movie, Who the hell does he think he is?
"What? The movie you were watching sucks anyways."
