He is a piece of shit but I dont think you weigh how fucked up juyeon is and it really shows. He continues to take pleasure in doing the most fucked up shii to the point that jiwook ends up in the hospital on the brink of death that goes beyond just a revenge. Thats you taking pleasure in doing fucked shii. In addition, he is no longer at the mental capacity to remember his actions
he wouldn’t be fucked up if jiwook didn’t fuck him up in the first place. jiwook also sent juyeon’s mom to the hospital after the shit he did to him, it’s an eye for an eye and he has every right to take pleasure in doing so. not remembering his actions doesn’t erase it, in the first chapters he’s obviously still the same lustful piece of shit and him loosing memories doesn’t purify him

juyeon is right idc
