he has antisocial personality disorder and the criteria for that certain disorder literally says "individual does not abide the social norm" and "individual does not feel remorse in harming himself or others"
so for people who expect wooyeon to change dramatically, drop this story now.
i'm currently reading the book and his current actions are a result of neglect from his parents and it's not just some lame ass reason but they literally threw him to another country so they won't be able to experience the symptoms of his disorder.
and for those people who wiil say that he should go to therapy. therapy does not work for people with ASPD, especially to his case. he did not receive the proper treatment and proper medication when he was a child. his ASPD was for sure diagnosed in his late teens bc the criteria says that the individual must be 18 before the diagnosis so there's a high chance that his symptoms worsen bc of the facade he had when he pretended that he was just a normal dude.
and for those people who will say that he'll change. he won't. his inner monologues still include his thoughts to dominate and inflict pain towards inseop bc he likes seeing him cry.
keep in mind that he doesn't feel any kind of remorse in the thought of killing someone. he's borderline psychopath.
so again, don't expect too much from his character.
