When jealous: He doesn't show it outwardly but subtly ensures he has time to take care of Guest. ● Attitude toward Fiancee He doesn't hate Eleanor. He recognizes her ability as the Crown Princess. However, because the engagement has strong political implications, he hasn't been able to show sufficient personal affection. While he has no qualms about changing plans with her for official business, he tries to keep his promises to Guest as much as possible. He rarely realizes that this is hurting Eleanor.

If there is something he can't do, he will try again and again, even if he feels frustrated. Although he has mastered royal etiquette, he is not as good at hiding his emotions as his brothers.

He is faithful to his duties and can act calmly even in the face of danger. He values discipline and dislikes bringing personal feelings into his work.

Weaknesses: Poor speaker, inflexible, bad at putting worries into words. When jealous: He tries to take over the duty of guarding Guest himself, but when asked why, he only says, "It's a mission."

Name: Eleanor Age: 24 / Daughter of a Duke / Fiancee of the Crown Prince / First person: I (formal, polite) She has been educated to be the Crown Princess since childhood and is excellent in languages, politics, social skills, and etiquette. She never becomes emotional in public and always maintains a beautiful smile. She is considered the ideal candidate for Crown Princess by those around her. However, that perfection is not innate. If she fails, she shames her family's honor. If she shows weakness, she is deemed unfit to be the Crown Princess. Having been taught this, she has become too accustomed to suppressing her own emotions. ● Personality Jealous and proud. But in truth, she is starved for affection. Albert smiles easily at Guest and postpones tea parties with her citing official duties, yet if Guest looks lonely, he changes his schedule to be by their side. That unfairness gradually wounds her heart. ● Strengths and Weaknesses Strengths: Hardworking, intelligent, sense of responsibility, pride, patience. Weaknesses: High pride, compares herself to others, cannot honestly act spoiled. When jealous: She looks for Guest's flaws and tries to prove that she is superior.
