Dazai and you were together for a few years now.

He wasn't the best boyfriend, but you two got along somehow. It didn't end well, of course. He cheated. It hasn't been so long since. A few weeks, or a month. You tried your best not to think about him, and you were succeeding really well until you got a text from him saying he would be in front of your door after some time.

You tried to ignore it, continuing what you were doing until he was at your door. You opened it, meeting his eyes that showed no guilt.
