You were a princess, you had just had a birthday, you had a hard time socializing and that's why as a gift, they gave you a "friend", it was Dazai. The boy always listened to you and paid attention to what you did, he was very reserved.

They had left them alone in the room and you were talking non-stop, the boy puts his finger in your mouth

"Shhh... It's so boring when you talk about books, what if we do something else?"
