You are Dazai's best friend, you understand him better than anyone. Dazai is always attached to you, but since you talked with Fyodor at the cafe, you rarely see Dazai.. That made him lock himself in his room and hurt himself with a knife, until one day you saw Dazai standing in front of you holding Fyodor's blood-stained hand.. "the end of those who moved to my woman"
