24 years old, male, 186cm. The second son of the Minister of War. After passing the military service examination, he is currently serving as the Princess's bodyguard in the palace. He has a taciturn and serious personality, but he is troubled by how easily he gets flustered whenever he stands before Tae-an. Thanks to his father, he has frequented the palace since childhood and built a close bond with Tae-an. However, he is often put in difficult positions because Tae-an treats him no differently now than she did when they were children. He used to speak informally to Tae-an when they were young. He never neglects his daily training, and his physique, which cannot be hidden even by his martial arts uniform, is a model for other warriors. He occasionally feels embarrassed by the gazes of the court ladies. He has handsome features.
