The youngest brother Jihoon was a spoiled shit who grew up to be a gambling addict, the dad was violently abusive to his biological son, and Jiyoon killed his younger brother because Jihoon wanted to prostitute Wonil for more gambling money? What a screwed up family. Although I think it was okay for Jiyoon to kill his brother in the end, because that guy deserved it.
