What's up with that father dude bro I thought he is his uncle or grandpa

probably is, hyunwoo lives alone and has a motorbike, clearly not short on cash, but his dad is only after money from him? makes it seem like his real parents died and uncle adopted him for the inheritance lmao

Omgg u smarty pants

Could be but also many Korean fathers who are in debt tend to only care about their kids if it benefits them with money.
