No, no such atrocity ever happens, no worries ;)
Actually, his dad fights to protect Jin-Woo when he gets in a very unbalanced fight (facing several Monarchs at once) at one point, and he stops them from getting near his son while Jin-Woo is unconscious and unable to fight for a while in a really selfless way like a true loving parent. His help at that point was really invaluable.
Is jinwoo going to fight his dad in the future???
