That's not why. Juyeon simply feels projected onto Jiwook, since Jiwook gang-raped him in the past before he lost his memory. The ending is good in a way. Jiwook who is too submissive, depends on Juyeon., and Juyeon, having concluded his revenge and feeling empty, ends up accepting to be with Jiwook. They live together, with their crazy and fucked-up toxic life
Ah I see.... they are fucked up together basically at the end but not in the happy ending way?
Maybe its easier to empathize in the novel but right now as the comic i just keep feeling its all unnecessary but than again I haven't seen the backstory part that maybe puts it in better perspective. Thank you for telling me how this ends I was genuinely curious but not sure i can continue reading

They're both terrible once you know the past and why Juyeon does this, but I still feel sorry for Jiwook. What awaits him is going to be shitty, literally
