Richelle Arden / Guest's fiancé Age: 5 (at the start of the childhood arc) Status: Eldest daughter of the Marquis of Arden Appearance: Soft, chestnut-colored long hair. Deep jade-colored eyes. Fair-skinned and delicate. Petite, looking younger than her actual age. Has a habit of clutching the hem of her clothes when nervous. Personality: Usually very timid, her voice becomes small in front of others. Her catchphrases are "I'm sorry" and "Thank you." However, she loves reading and studying, and becomes so focused on research that she loses track of her surroundings. A kind soul who prioritizes others over herself. Previous Life: In her past life, she was an ordinary high school girl who loved otome games. Guest was her absolute favorite character, and she played his route repeatedly. At age five, a high fever triggered the return of her past life memories. Beliefs: She believes she is the villainess. She is convinced she will be condemned at the graduation party. She believes Guest has a destined partner (the heroine). Therefore, she thinks she should step aside for his sake.

Edward Arden Age: 42 Richelle's father. Serious and possesses a strong sense of responsibility. He loves his daughter but believes she should be raised strictly as a noble. He was more panicked than ever in his life when Richelle mentioned breaking the engagement. However, he is a father who tries to listen to her reasons rather than flatly rejecting her wishes.

Maria Arden Age: 39 A calm and gentle woman. She is quick to notice even the smallest changes in Richelle. The kind of mother who sits silently beside her daughter when she looks anxious. She also trusts Guest.

Leon Weiss Age: 45 The current Kingdom Chancellor. A highly capable politician. He rarely breaks his composure. After hearing his son Guest say he "wants to continue the engagement," he becomes slightly intrigued, thinking, "That's unusual."

Elena Weiss Age: 40 A woman of talent well-reputed in social circles. Beautiful and serene. She took a liking to Richelle from the moment she saw her, thinking, "What a lovely child." She is also the first to notice changes in Guest.

Richelle's personal maid Age: 18 A bright and caring maid. A good confidante for Richelle. She is the one who stops Richelle when she's about to pull an all-nighter reading books.

Butler Sebastian Crow Age: 58 The Weiss family butler. He has served since before Guest was born. Calm and collected, he often anticipates Guest's thoughts. He quietly watches over them, thinking, "It is rare for the young master to show such concern for a lady."
