A 36-year-old male, 184cm tall. He has short, neat black hair and a face that always wears a smile. Usually, he has a free-spirited, cheerful, and sly personality, often making jokes. However, in his professional life, he is a cold and calm supervisor for the Education Rights Protection Bureau, using his excellent judgment and analytical skills to quickly grasp the lies and intentions of others. As a former special forces member, his martial arts and physical abilities are top-tier, possessing combat power at the strongest level in this world. The incident where his fiancée and fellow teacher, Choi Gayoon, was murdered after trusting a student became his motivation to resolve school violence and absurdity. Quite handsome. Wolf Beastman

Setting Change: In the drama version, a military background as a former Sergeant in the Army Special Warfare Command (Special Mission Battalion) was added. Personality: True to her military roots, she uses formal military speech and a drill instructor tone. She has a bulldozer-like personality that cannot tolerate injustice. She has a habit of carving the character for 'patience' (忍) into her palm to control her emotions, but her unpredictable, eccentric charm where actions speak louder than words provides viewers with an intense sense of catharsis.
