Of course he's scared. His brother is acting totally the opposite and he met Joohoon--he's scared that Joohoon and him somehow connected. And he's scared, too, that his brother isn't a little wimp begging for help, but is being pursued by SiWoon, whom Jiwook wants to be HIS pal. Maybe he fears that his brother is gonna conspire with Joohoon to get back at him.
When he was alone in the bathroom, he was talking about wanting his brother to stay dead and he send the dvd to the bullies to beat up SiWon.
Now, if this is a twins switch, it makes it more complex (and brain-teasing).
As far as comparisons: it's tacky and it's damaging. But that doesn't excuse treating your brother as if he deserves to be everybody's bitch and should die.

Anothet thing is that I haven't given up on the possibility (yet anyway) of the twins switch. If he thinks that JooHoon has realized he did a switch (is that what the blackmail is about) or the JooHoon knows Jiwook set up his brother's rape (if that's what happened), then both of those are dangerous to Jiwook, reason for terror, and reason to worry about what his brother will remember or do.
Jiwook is afraid of Joohoon (naturally ,he's dangerous) and of his brother (who is upsetting his plans/life/position, and possibly a lot more.)

I think you should read the new chapter again, cause it seem even before his brother soicide and change, and before the rape thing, he was scared of him.
he always felt, at least that how it seem in this chapter, like his brother want to get rid of him - the babble that seem like his brother say "he hate him", the brother never said to fox he hate him, at least I don't think so. I think the brother did care about him, but to fox it seem the opposite.
and everyone, that don't even know him already say how much better his brother is from even before getting to know the two - the people that show up in this chapter.
so again, I think that hate and jealousy was born from a long long time ago from a very young age from the act of the others always comparing him to his brother and how much his brother so much better then him. and yeas I think he always was scared of him, even before the change.
in the bethroom he talk about how his brother existance threatens his life, what is weird since the brother don't seem like the bully type. this new chapter actually made things much more clear and make sense why the twin existance threaten him that much. and I blame a lot of the perents, that never praise him, only his brother. not cause he don't deserve to get praise, but only cause of preference. the perents prefer the brother over fox, what can make him get fuck up, and can destroy a family. perents should never do that!!
I don't know about them switch or not, we don't have enough details. but one thing is for sure, fox was suppose to be rape by that crazy guy. I"m guessing the brother protect him by agreeing to be him instead. but I don't think fox plan he soicide about this. he just got usud to be alone without him since he always wanted the perents to notice him. but my guess is they never did and kept going to his brother in coma so....yeas.
I never said it is excuse for what he done, but for now we don't know what he done or what been done to him or happen or who blackmail who. and from what it seem, the most crazy fuck up guy is the guy that called fox then fox himself that scared of him most of the time. so I say - who worse? to me it the crazy guy then fox that at least had some common sense. and didn't do anything to his brother even if he is insult him, what seem more like Tamin said, a dog that only bark. he wasn't someone that Tamin care much about cause he isn't dangerous like that crazy guy.
I"m not saying he is a good person, only that it realistic. people like that EXIST only cause of how the family prefer one brother/sister over the other and make them hate each other! it is something real! not that we should forgive him, only we should learn never to do that in our life or our family! cause it can ruin the family from the inside!!
finally a name I can remember - the fox, the brother. well I can't say I "like" him now, or feel pity for him. but I get where his jealousy come from that been compare to your brother all the time all your life, and live in his shadow can be hard.
and I don't think he know or could ever predict his twin brother would kill himself. since he was angry and scream at that guy that arrange the rape, there is no way he know it would happen.
I get that he try to save himself in the first place and use his bro, but again I don't think he could ever predict his brother will kill himself!! blaming him is the easy way, but not the right way cause it's not true. so it's not just he didn't care, he just wanted to protect himself and use his brother for it.
yeas it's horrible, yeas it is selfish. but that doesn't mean that his jealousy in his brother wasn't a thing that happen in a family, it actually very natural thing. not the rape of course, but the Humiliating treatment is a common thing with brothers that jealous.
actually it really common in a family that prefer the older brother/one of the brothers over the others and always praise him instead of giving an equal love to all the brothers - I hate the parents and the others for it much more!!
I still didn't forgive him or anything, but that just show how the parents wasn't the best, and always look down on him. what saying something about "them" then the brother.
I really like how it is going! XD I love how there is no a pare evil perason here.
well apart from the guy that arrange the rape and call fox in this chapter.
