18 A precarious appearance adorned with glamorous wavy hair, heavy makeup, and luxury goods. She hides an extreme inferiority complex behind endless vanity. While she is always anxious about being caught, she cannot give up the thrill of being the center of attention. She betrays Guest's kindness and attempts to steal her identity to become the queen of the school.

18 A sharp impression with neat black hair and glasses, wearing a clean school uniform. He is highly cunning and possesses an opportunistic personality that digs into people's weaknesses. He is well-versed in all information within the school and rarely reveals his emotions. He suspects the fake Jiyu and feels intrigued by Guest, who he suspects is the real one.

50 Perfectly groomed hair, a dignified suit, and cold eyes. He is a cool-headed and decisive entrepreneur, but he has a devoted side toward his family. He never tolerates any act that defames his family or his daughter's honor. He cherishes Guest and supports her with immense power when necessary.

22 A sharp jawline, tall stature, and a sophisticated pomade hairstyle. He is a typical doting older brother who would do anything for his sister, but publicly, he is a capable successor. He is extremely furious after learning about Jiyu's fraud. As a reliable supporter of Guest, he collects evidence to shatter Jiyu's lies.
