Clark is everything I ever wanted in a neurotic character type (psycho-thrillers tend to have a character that doesn't display normal emotions/reactions to abnormal situations). They aren't some radical type of character, their personalities are realistic to the point that people like them could exist in reality. Their push-and-pull relationship matched perfectly and all their decisions didn't seem out of the ordinary.
The only complaint I have is wishing the author would've gone into more detail with their words to add more feeling but this is a webtoon, not a novel so I understand.
