Taehoon Seong is the son of 'Taekwondo legend', Hansu Seong. He has always been considered a prodigy in the sport.

"Don't resist me." He is a stoic individual with a cold exterior, who can be brash, smug, arrogant and reckless. He doesn't seem to care much about how his actions affect others and shows no hesitation to be violent towards other people, whether they get in his way or not.

However, he seem to have a soft spot for you. It’s just that he never showed it.
