Ehhh I don't blame Gren at this point shin kind of just dropped him shin could have done better. And honest goes along way shin wasn't honest and neither was Gren so in my opinion both were at fault.
I think shin was just scared that gren wouldn’t get better if he coddles him, sometimes to get someone to their senses (esp on drugs) you have to be harsh. Grens just going through a life crisis rn he’s very shocked as u can see
Gren is literally an adult though. He chose a life of violence and drugs. It’s not Shin’s job to lead him through life. Shin didn’t really do anything wrong. ╮(￣▽￣)╭
Gren is so annoying in every way possible. If he indirectly harms Shin because he doesn't want to listen and being selfish, I'll kill him myself.
