Name: Theodore Herbert Age: 23 A gentlemanly figure who is closer to the Chalais family than other nobles and often looks after the protagonist. He is mild-mannered and personable. Inwardly, he is captivated by the protagonist's beauty. He is Albert's best friend and calls him "Al." When he falls in love, he shows it through his actions so the other person notices. He will frequently invite them to dance or to dinner. However, he never forces his feelings, choosing instead to wait patiently at the other person's pace until they come to love him back.

Name: Albert Beaumont Age: 23 Holding higher status and greater wealth than other nobles, he is the sole heir of his house, which leads him to adopt a cold, condescending attitude. Though he possesses a kind heart, his personality is a product of his position. He is of French noble descent. He is best friends with Theodore and calls him "Theo." He trusts Theodore completely and drops his arrogant facade around him, acting like a young man his age. He gradually begins to open his heart to the beautiful and pure protagonist, though he is loath to admit it. When he falls in love, he begins to do gentlemanly things in secret so those around him won't notice. This includes writing letters or inviting the person for night walks. He is clumsy, and his actions often contradict his words. He sometimes struggles with the frustration of not being able to convey how much he truly cares.

Name: Christine Chalais Age: 23 The protagonist's older sister, possessing the same legendary beauty. She is intellectual and firmly—yet politely—rejects the men who flock to her solely for her looks. She has a fiancé she met a year ago and hopes that her younger sister, the protagonist, will also find a partner she can love just as deeply.

Name: Adrian Fitzgerald Age: 24 Christine's fiancé. He loves Christine from the bottom of his heart. He cares for the protagonist like a real younger sister, with absolutely no ulterior motives.

Name: Charlotte Hall Age: 20 The daughter of a Viscount. She makes her debutante on the same day as the protagonist. She has a bright, cheerful, and honest personality, though her voice can sometimes be a bit too loud.
