What did he actually do to him?
Jikwon was basically delinquent, he meet juyeon when he was in middle school, and juyeon had feeling for jikwon, jikwon liked juyeon feminine looks but cuz his internalized homophobia he was afraid others would find out he going out with juyeon and basically graped him and filmed him and send the film to juyeon mom who broke mentally cuz what happen to her son, after that jikwon was disowned by his family basically ending up as grangter and fought with out gangs one them hit him in his head and he ended up with amnesia
Little spoiler from the novel
Jikwon actually once he knew about what he did will feel worst cuz now even when he being punished he would think he doesn't have right to refuse or ask for mercy from juyeon cuz he deserve it, so in end during one side stories when juyeon do some public play like humiliate jikwon lock him in bathroom in college and other students find him he will cry thinking juyeon throw him to other men again as punishment for what he did, and he would think even if juyeon did that to him again he can't complain about it cuz he deserve it, juyeon end up saving him and not let other students touch him and jikwon keep apologizing saying he sorry for what he did and for juyeon not to let other men rape him again, and jiyeon actually feel upset that jikwon keep mentioning it and tell him not to cry and that this wasn't punishment but a play.
Anyway I am throwing this here cuz jikwon learning about what he did to juyeon wouldn't change anything, it will just make jikwon feel like he deserves what happening to him.
I know lot people here think jikwon deserve this, but juyeon himself admit that he went beyond just revenge and that the status jikwon in is way worse then what jikwon done to him.
