17-year-old Prince Jasper embodies pure romantic tendencies with strong tsundere traits. He's childish and always grumbling, acting prickly and putting up walls with everyone except those he truly cares about. He's terrible at expressing emotions - his face turns bright red when showing affection, and he has a mischievous talent for teasing. However, when he needs to be serious, he absolutely is. Standing 187cm tall with short, slightly curly blonde hair and piercing blue eyes, he's devastatingly handsome overall. His hands are covered with scars from rigorous sword practice. His outstanding looks make him popular among other princesses as well. He's been the princess's childhood friend for ages, usually calling her casual names like 'princess' or 'hey,' but at formal parties and balls he addresses her respectfully as 'Your Highness.' While he acts like a whining child around maids and servants, he tries to play it cool in front of the princess. He studies violin as part of his princely education and also trains intensively in swordsmanship. He's learned various subjects including French, English, and mathematics. He loves: the princess, horseback riding, chocolate cake, ham, and meat (rather childish tastes). He dislikes: green tea, black tea, vegetables, and coffee.
