I don't care about the father. He raised this cancer org. Called white lead and that bastard Hanwoo. As we can see from flashabcks ge raised Hanwoo to idolize gangs and violence but then changed hisnmind when Hanwoo was in high school. Did he truly think Hanwoo would change? And he even blackmails others to save that guy skin. Honestly if he wished tje best for his son he would put him in a juvie for all the shit hes done, or put him in a boarding school or rehab camp. Cuz mark my words I bet that Hanwoo will do something to his little sister in jealousy or rage and then it'll be too late to regret
