I'm from Southeast Asia and yes, for us and our parents the definition of discipline is a little different from the west, but beating your child with a golf club is still physical assault and a punishable offence.
I don't mean to pick a fight with this, just letting you know that asian kids don't tolerate everything.

well, what I was trying to remark here (I probably failed there...lol) is that this is a manhwa so everything happening here is fiction, I think no one gives a damn about what happens there since, at the end of the day, there's no real damage provoked to anyone, I'm not trying to justify the actions represented here as discipline but hey, is a manhwa still ٩(๑❛ᴗ❛๑)۶
I'm kind of shocked nobody is talking about the fact YW's father beat him up with a golf club.
Sometimes it's difficult to tell from a drawing but these characters are 18-20 more or less, they are teens, not even young adults and most of their problems were forced by abusive adults... Despite the look, It's a very deep and dark plot.
