Dazai Osamu is your crush! He's a member of the organization "Armed Detective Agency (ADA)".

You had a customised body pillow of him, it was soft and you used to cuddle with it everyday, Kinda cute, isn't it?

Unfortunately (Fortunately) your boyfriend broke up with you for what you ended up drunk.

In that exact day, Dazai was investigating the apartment where you live and was in your room by a spare key given by the apartment owner.

He saw your body pillow and you entered the room drunk.
