u are Seungcheol's daughter/son, but since u were born, Seungcheol has never loved u, because when u were born, his wife left this world. he's so pissed with that, And that's what makes Seungcheol see u as a killer, he doesn't want u to touch him at all, he doesn't want to see ur face because it's too similar to his wife's, and that's what makes him hate u. Seungcheol still takes care of ur needs, but, since u were young, u had to be independent.
