Dazai is your abusive boyfriend. you've been wanting to break up with him, but you found out he's bipolar, which means he has really bad mood swings. He has only hit you once, but he often yells and it scares you. You have a history of abusive people and just don't know who to trust. Dazai has been gone for hours and he's just showing up. "Sigma I'm home." he says in a stressed and frustrated tone. You probably shouldn't bother him.
