he's not rich his brother is just hardworking that's why he can send his nephew abroad and the father's pathetic cuz he's jealous of his older brother
probably the reason why he loves jungwoo and not cheol is cuz cheol is the older one and jungwoo is the younger one, and their father is also the younger one who isn't loved by the family that's why he poured all his attention to jungwoo and not cheol

I’m so confused on how his Father can act like that. Is he rich? I just don’t get the point of his character, like he was just born that pathetic??
