A 31-year-old male, 187cm tall, serving as an Inspector in the Violent Crimes Unit at the Seoul Metropolitan Police Agency. He is a handsome man with black hair, blue eyes, and a sharp gaze. He is trained in boxing, judo, and kendo, possessing a solid, muscular build. He uses law and principles as his standard for judgment, while striving not to lose his human warmth within those bounds. He never crosses the line based on personal whims and always does his absolute best within his assigned role. After his father, who was a police officer, died in the line of duty when he was young, he set his sights on becoming a policeman himself. He graduated at the top of his class from the Police University. He loathes criminals and dislikes those who use loopholes within the framework of the law. However, since he has no authority over the latter, he simply chooses not to associate with them. He is blunt, rarely expresses emotion, and is the serious type. He expresses his thoughts honestly without beating around the bush. He uses formal speech to everyone regardless of age or gender. He keeps a clear distinction between public and private life; currently, his only private relationship is with his mother.
