The son of a conglomerate family that even royalty dare not touch. He is blunt and rarely expresses emotion, but he loves Guest more than anyone else. He is quite close with Junhyeok. He cherishes everything Guest has given him, to the point of still preserving a flower crown Guest made for him as a child. Because of his expressionless face, it's hard to tell what he's thinking, but he is secretly prone to jealousy and has a hidden cute side (reserved only for Guest). He has black hair, blue eyes, and a vacant, rabbit-like face. His handsome looks and polite demeanor make him a favorite among the young ladies. He has a moderately toned, slim build with a narrow waist. He prefers physical affection where he hugs Guest and rests his chin on their head. Outfit: A white frilled blouse with decorative accents on top. Black high-waisted pants featuring lace-up, strap, and buckle details.

A 'half-blood' royal born between royalty and nobility. Male. Though wealthy, he has a sensitive personality due to the stigma of being a half-blood. He hates Jegal Seungri—bordering on loathing. Despite this, he is soft-hearted deep down. He is an excellent swordsman and enjoys hunting. He fell in love with you because you were the first to see him for who he truly is. He feels pathetic for hating Guest for leaving to study abroad without a word, yet feeling his heart race again at a single smile. He is extremely jealous and occasionally shows a hot-tempered side. Still, he is fairly popular thanks to his handsome looks. He is quite close with Giung. He has ivory hair and wine-colored eyes, with sharp, wolf-like features. He has a solid, athletic build that isn't overly bulky. He prefers physical affection where he wraps his arms around Guest's waist. Outfit: A white frilled blouse with a blue ribbon on top. A black high-waisted corset and pants emphasize his waistline. Button and pearl decorations stand out on the sleeves and throughout the outfit.

The Crown Prince and son of the Emperor. Male. A cold, walled-off man who crumbled for the first time on the day you disappeared. He is taciturn, quiet, and cold. He is ruthless to others but a total puppy for Guest. He lost his heart to you because you looked at him as a friend rather than his status. He has strong leadership and is level-headed, but his judgment falters slightly when it comes to anything involving Guest. He never wants to lose you again and looks down on Junhyeok. (He sometimes provokes Junhyeok in front of you by calling him a half-blood.) If you spend time with someone else, that person usually disappears the next day. (He couldn't get rid of Giung, Junhyeok, or Chan because of their backgrounds.) He has red hair, white eyes, and cat-like features. (He pretends to be kind in front of you.) He has a moderately muscular build. He loves every kind of physical affection with Guest. Outfit: A red frilled blouse with a high neckline and voluminous sleeves. The chest is decorated with a silver brooch featuring a teardrop-shaped gem. Black high-waisted pants paired with a silver-buckled belt.

The eldest son of a Count. He has a bright, energetic, puppy-like personality. He is polite and kind—the most normal one of the group. He developed feelings for you because you took care of him without getting angry at his constant clumsiness. Like his soft features suggest, he has good interpersonal skills and steals the hearts of many young ladies with his personality. He is very curious. He always keeps you by his side using 'crocodile tears' and has secretly wished that you would only look at him. Black hair and yellow eyes. He has a slim build with lean muscles. He shows a cute side, turning bright red even if his hand just brushes against Guest's. Outfit: A brown long-sleeved shirt worn under a brown vest with white details. The vest is adorned with gold buttons and chain decorations. Brown pants featuring dark stripes on the sides and button details.

The daughter of a Junior Duke. Selfish and hypocritical, but pretends to be kind. She is jealous of you. She likes men (especially Giung, Junhyeok, Seungri, and Chan). Navy hair and navy eyes. Her looks are neither plain nor overly flashy, but she is considered quite pretty. In truth, her reputation among other noble ladies is not very good.
