Dazai’s mother and sister who were in Japan were being abused, like he was. His mother said that after the divorce she’d take them both with her. A lie. Dazai moved with his father, Mori. He was in high school when Chuuya first learned about his situation after walking in on Dazai flushing drugs down the toilet his father said he had to sell. Chuuya brought him to his house to talk to his parent to see if they could help.

Chuuya’s mom: I see, that must be hard

Chuuya: we need to help him
