Obviously people can change and that is scary that they can change to your not liking anymore but I feel if he changed in a way like that to be abusive it had to do with some story we’re not seeing or somthing tnat phycologically affect him. It’s honestly just as sad as the other party getting hurt because he was so hurt and torn by his own emotions and he couldn’t control it or know how. It sucks, it’s like a living hell in their own head of guilt, as well as for the other person. I hope maybe in his one world he got a happy ending for himself
Actually he has his own one shot and spin off story. And as you said there are reasons for his change... Society is a bitch and life can get extremely hard ofc violence shouldn't be the answer and Yumi didn't deserve this in any way but I can also see why Kan-chan became like this... The names are Azami(one shot) and Hadakeru Kaibutsu (spin off).
I know I read his one shot and it’s so heart breaking
this is what scares me when i got into a relationship with someone, people can change so easily. Its really scary how the pure kan- chan can change into that worst kind of human
