Raping your gf, sending her pics, then pass her around. But he is still just a child? Are you crazy? He raped the ml when he was still a mfuking MINOR! And gangraping him. If a "child" can rape he is not a "child" anymore. Don't defend a literal rapist, by labeling them as just a child and he didn't know better. Plz.
Nah it's fine maybe I wrote it in a confusing way. ("-.-)I don't think both of them are defendable but if I were to look at where Juyeon is coming from, I understand his feelings but I wouldn't justify it. While jiwook actions in the past and in the present are just unjustifiable. He is a terrible person.

This is why I don't like people justifying his actions. He didn't even want revenge in the very first place. When he visited jiwook at the hospital. It showed in the novel that he still had some lingering affection for jiwook.He felt some type of way after seeing that jiwook lost his memory and only then did he decided to do all of it. It wasn't revenge but some sort of mess up mindset after seeing the person who he liked has put him through so much just forgot him like that. It's obsession mixed with resentment. From his stand point. It's understandable but not justifiable. Same goes for Jiwook. There are ppl in the comments section of the novel victim blaming Juyeon because he willingly associates himself with jiwook in highschool even knowing that jiwook has history of doing stuff like send pics and videos(inappropriate of his gf) on the internet but he is just a child. He doesn't know any better. He wouldn't have known that he would get rape like that.
