1- Mori did physiologically, and physically abuse Dazai, but he did tend to wounds and stuff, and comfort him, but in a very manipulating way, that would gain trust, so Dazai could act as a sort of dog. (#weH8mori.)

2- Chuuya was very good with children, having been in the Sheep, and treated Kyouka very well!

3- Akutagawa drives Chuuya home after he's had too much to drink like the good son he is 😔
