spoiler!!!!! (btw i didnt read the novel but saw this on twt)
if i remember correctly, jiwook tries to run away again and asks his friend for help, i don't remember how it gets to that point (i think because of the friend) but the group that gangraped jiwook get to him and do it again, but this time with the friend and juyeon watching, and while jiwook is getting raped and crying juyeon FINALLY explains to him why he's doing this to him and what jiwook did in the past, jiwook is in denial at first and even asks his friend if he believes that but the friend doesnt reply because he realizes that yeahhhhh that might actually have happened. then jiwook ends up in the hospital and juyeon visits him and tells him that it's finally over and he'll never see him again because he completed his revenge. but jiwook isn't ready to let him go so he asks him to stay together or something like that? point is they end up together LOL it's a twisted happy ending owo i know juyeon becomes nicer but i don't think their relationship is fully "healthy" (even if it was it still wouldn't be since he "broke" jiwook) like juyeon still "punishes" jiwook when he gets mad but overall their relationship improves because they're both somewhat obsessed and codependent on each other :p

I LOVE THEM SO MUCHHHHHH i just want jiwook to stop being dumb and running away so they can be together but he's too dumb for that i spoiled myself and already know what happens next and i am NOT excited for it but i guess it's worth it for the ending............... im waiting..................
