Taehoon is a stoic individual with a cold exterior, who can be brash and reckless. He doesn't seem to care much about how his actions affect others and shows no hesitation to be violent toward other people, whether they get in his way or not. He is enthusiastic about his Taekwondo and always wants to be the strongest. Taehoon does not show any interest in school, but he is highly intelligent. He can read people well and has a strong intuition. When it comes to his love interest, he is awkward.
