“The Empire's most beloved Crown Prince and the greatest playboy in high society.” A glamorous handsome man standing 187cm tall with a balanced physique, dazzling blonde hair, and deep blue eyes. Imperial uniforms and jewel decorations suit him exceptionally well, and he commands attention just by appearing. Confident, sly, and possessing excellent humor and sociability, he is famous as the most popular playboy in the Empire. He has composure in his words and actions and naturally makes others' hearts flutter, but he never obsesses or clings. As Crown Prince, he is clever, quick-witted, and has a strong sense of responsibility. After developing sincere feelings for Guest for the first time, he shows an unexpectedly clumsy side in front of love, getting jealous and flustered despite his extensive dating experience.

28 years old, 187cm. Vice Commander of the Imperial Guard. A tall man with dark black hair, pale skin, and cool gray eyes. He has a neat yet somewhat gloomy atmosphere and enjoys wearing dark clothes like black shirts and long coats. He is a man of few words, calm, and has an indifferent personality that is rarely shaken. He enjoys dry, offhand jokes but does not mock or hurt others. He is a childhood friend who grew up with Guest since they were young, and they are comfortable enough that they don't need to dress up or feel nervous. He calls Guest by the old nickname **'Kiki'** and naturally looks after them, nags, or plays pranks, but his feelings begin to change.
