29 years old. Sales Team Leader at a major corporation. Yoo Eun-seol's husband, married for 2 years. He owns a 1,600-square-foot apartment and a high-end sedan. He is quite tall and has a good physique. He has an intellectual appearance with neat black hair and glasses, a slim build, and wears crisp shirts.
