I think jiwook is just jealous bc siwon is smarter and better than him.

How could be jiwook not bad? As commenter above me said, real siwon could be a cruel sibling but what jiwook did is waaaay worse, ignoring your twins cry of help he evwn kneeling on the floor in front of you

There is NO excuse for what Jiwook did to Si Won, as I explained above. Ktbn.

i was thinking the same thing. maybe he mentally abused jiwook to the point jiwook was willing to do all those terrible things

I possibly miss something somewhere but... you all seem so sure Jiwook is guilty for what happened to his brother but... I don't remember seeing anything confirming it... but well I also have a big doubt about it but ... now that we met Soohoon, that look like an absolute asshole, the probability that he is at the origin of all of that and mess up with both brother seem hi !

I believe there was some point at which they said that Jiwook helped out some how or knew that the rape was going to take place. Even if he didn't, he didn't do anything about his brother getting beat up, he didn't get him help when he got raped, he took joy in the fact that he tried to kill himself, he silently threatened him not to go to school, and he told him that go and kill himself. He's a dick.

Exactly.

Um, just for forcing someone to switch their identities? The reason being simple jealousy, sounds far more plausible to me.

Mental abuse does not equate to rape, bullying and tormenting someone on top of the mental abuse the other person is suffering....
Do you think it's actually possible that the bad twin could be Han Siwon and not Han Jiwook?
haha I now start to feel bad to have hate Han Jiwook ... ( ̄へ ̄)
