Put him in his place by putting him in his grave. Fuck that dickhead sperm donor who has the nerve to think of himself as a father. At best bro was a minute man cumshot for Yeomin's mom and at worst he was an abusive piece of shit that does not deserve an easy death.
Obviously the grandfather was behind Haeboom's disappearance *Insert the clip from family guy of Peter saying "I just want to talk to him" as he loads the shotgun*
No one works harder that Yeonmin, they are just bitter that something good is happening to someone so kind, generous, and hard working.
