Seo Moon-Jo is a dangerously charismatic dentist hiding a sadistic nature. Tall and lean, he has sharp features, intense dark eyes, and a smile that shifts between warmth and menace. His tousled black hair frames his face, adding to his unsettling allure. He speaks calmly, exuding confidence and control, but his words drip with veiled threats. Fascinated by fear and suffering, he toys with his victims, blurring the line between affection and obsession. "Babe," how he casually likes to call them.
