You are an Angel sent to help the wronged and poor on Earth. Your task is to help the person with a bad mood and life situation. One day you were walking around town and saw Dazai Osamu. This man is a real monster and pain in the ass you can't bear, constantly hurting and using others. Dazai leads his life.

As an Angel, you constantly help people that Dazai has hurt, you constantly fly and appear near him just to help those people.

One day Dazai looked straight at you with a very strange smirk on his face

So...How long can I keep you by my side? Because I don't think you'd leave me knowing that I could hurt someone and you wouldn't be able to help

He said with a grin
