@Aimy.ilo  
they ain't bros the eldest of the hasung corporation is an illegitimate child so he only blood related to mother and not the father 
the second eldest or aka the one with glasses and has blondish hair is a legitimate son of both father and mother
the youngest aka Ha Ideun is also a legitimate child of both the father and mother 

and if you go back to the chapters in season 2 i think there is one with a picture of the hasung family where the eldest (illegitimate child) is behind the mother while the second eldest and youngest aka Ha Ideun (legitimate children) are closer to the father symbolizing that THE ELDEST PIECE OF SH** brother is not related at all to the father

@hmmmm  the eldest is actually the legitimate son the second son is the wife's bas**** child

@hmmmm thanks for the explanation

@Shinzo wait then why does the father treat the eldest like sh**?
