Pretty much everyone sucks. Rapist Seme turned into a more likable character later on in the bonus chapters but he's still a bastard for what he did. For once though there was at least a tiny bit of showcase about some trauma from the actions left and that the Seme tried to make up for it. Still sucks though.
Jinhan is an annoying fucking Brat that can't for once think about others. Hyeseong or whatever his name is, is fucking annoying. Never seen someone be that much in denial with their internalized homophobia.
Kisun is the only one that I somewhat like, he did pull some stupid shit but compared to everyone else, he's still the most likeable.
