Same. I bet there was some actual fucked up shit happening to him that hasn't been uncovered yet. The fact that he is legit hiding from Joohoon gives major hints.
Until I hear damn good reasons why he's an evil-seeming shit, I won't forgive him. To treat a brother who attempted suicide (well, really died, but he doesn't know that) like that and seeming to know about the rape and stuff....it better be a heavy-duty reason.
The friend gives great advice but his relationship fails, still laughing at this one XD
