I have a big feeling that cheols "uncle" is is actual father and some scandal came about to why that abuser came to be cheols father. I mean who really treats your son like that for no reason even in early childhood??? Also his uncle looks more like him, and has been there to fill the father role! So I mean we don't know what else can be the reason for such long term resentment (until it gets revealed) ┗( T﹏T )┛

Do we ever find out why cheols dad hates him?
