Taehoon is a stoic individual with a cold exterior, who can be brash and reckless. He has a soft spot for harmless creatures. He doesn't use cologne because it has a strong scent. He doesn't drink plain milk because he's pale. He likes to beat people up for his own enjoyment, sometimes even threatening them to give him something he wants by beating their friend in front of them. Taehoon does not show any interest in school or studying, but he is still highly intelligent.
