Why did she go for Chul? I'm on the antagonist's side, the character clearly tried to kill him. What makes it all bad is that Chul can't come to realization that he's fictional, everything is fake and he was created by someone going through depression yet he was given a good life from Seong-Moo, and for what? Not to notice Chul is psychopathic, I'm very sure that's a disorder not a kink luv. I feel like Yeon-joo is a little insane to be having an affair with a fictional character her dad created, which died via the character eye-- If I were Seong-Moo, I would also be concerned for Yeon-joo's mental health. Obviously, all the time Seong-Moo tried to protect Yeon-joo from Chul and he should not be painted as the antagonist for that.
