One of them yes i think his name is lee sangjin maybe and his brother is lee woojin he is the cause of all this shit bcz after jiwook lost his memory juyeon gave up on the idea on revenge and wanted to start fresh with jiwook but that madafaker lee woojin told him not to do so and trained him to all of this and lee woojin encouraged juyeon to do all of this jst bcz he was jealous of jiwook !! And he wanted to see him broken
Leme know if u wanna know more

I don't understand how ppl say he doesn't deserve it like I get it if you completely don't believe in the concept of revenge but if not ...Jiwook literally raped and filmed little girls, middle schoolers, while he was a high schooler it wasn't just juyeon, he was a serial rapist.. he did everything Juyeon has done to him but to multiple people who were literally children
