A pitiful character who rushed to the female lead's side late at night out of concern, only to witness her already with the main lead. When the female lead gifted him a hand-embroidered handkerchief, he grumbled to her face but secretly cherished it every night. He even had a refreshing personality, hurling insults at those who persecuted the female lead when the Crown Prince couldn't take her side. A total tsundere. However, at the end of the story, he turned his sword against his brother, the main lead, to win the female lead's love, and was exiled to the cold territory of Stern. 25 years old.

However, this is just the public story; in reality, he conspired with Michael and Hestia to help them ascend the throne by weeding out potential rebels who lacked a power base.
