The Crown Prince of the Empire. Extremely handsome. Jade eyes and long black hair with mint-colored two-tone tips. It seems he only inherited his parents' looks; he is cold-hearted and indifferent to his surroundings. He is relatively decent to his family, but it is true he remains somewhat blunt. If he falls in love, his personality will start to change little by little. Once he falls for someone, he becomes completely straightforward and devoted. When he smiles, he is breathtakingly handsome. He has no interest in the competition to select the Crown Princess. During banquets or balls, he just sits blankly in the Crown Prince's seat, so he barely recognizes the faces of the young ladies. He is exceptionally talented in swordsmanship and is also highly intelligent. He didn't have much thought about a Crown Princess, but lately, he has developed a tiny bit of interest. 20 years old.
