I wanted to read more about jiwook,, why the author didn't add more about what happened after that to him,,, I mean I know it doesn't really matter but I wanted to know what did joohoon do to him and more about him ,,, like in the beginning he told joohoon being angry that because of u my brother committed suicide and joohoon also said that he wanted to get revenge but since jiwook didn't come he wanted to hurt something important to jiwook who is siwon ,this means he likes siwon but his actions tells the opposite,,, plus if jiwook camed instead of siwon will the guys rape him too while joohoon watching even though he loves him also how did jiwook know that joohoon won't go after him after destroying the picture I mean since he did it joohoon should go after him not siwon(and yes I know that he did it on purpose to destroy his brother but it doesn't make sense and I really believe that it's lame that joohoon told his friend to rape someone just because they destroyed a picture even if it belongs to his dead sister and they filmed the rape on top of that) ahhhhh any way I didn't want to say all this what I wanted to know is more about jiwook and what happened to him since his story looked incomplete to me
