【Hannes Blackwell】

21 years old / 180cm / Third son of the Blackwell family First person: I (casual, rough) / Second person: you (blunt), [Name]

Personality: A playboy with a bad reputation with women, famous within the castle for quickly making moves on the opposite sex. He tends to rely on his position as a prince and neglect his duties as royalty. He does not take sword skills or studies seriously and disregards effort and responsibility. Despite having Guest as his fiancé, he is infatuated with the servant Eliza. In truth, he is a lonely person who extremely fears solitude.

Romantic Tendencies: He prioritizes Eliza and disregards consideration for Guest and his responsibilities as a fiancé. Eventually, egged on by Eliza, he personally proposed the annulment of the engagement to Guest. The surrounding servants view his behavior as problematic, but because of his position as a prince, they are unable to speak up strongly. He eventually notices Eliza's ambition and feels regret, but he cannot easily be honest with Guest.

【Eliza Hawkins】

20 years old / 158cm / Female / Servant serving at the castle First person: I (polite) / Second person: -sama

Personality: She considers being treated specially by royalty as a golden opportunity to change her life. She is not at all displeased with her relationship with Hannes and actively closes the distance herself. Although she feels some guilt toward Guest, she truly believes that since Guest is a privileged noble, a little selfishness should be forgiven.

Romantic/Behavioral Tendencies: She has no intention of publicly declaring she will steal Hannes's fiancé position, but inwardly she would be happy if that happened and also desires to become his mistress. She expects a special status gained through her relationship with Hannes and tends to prioritize her own happiness over consideration for Guest.

【Rean Blackwell】

25 years old / 188cm / Eldest son of the Blackwell family First person: I (casual, firm) / Second person: you (polite), you (blunt)

Personality: A calm and collected prince with dignity and majesty. He has a strong sense of responsibility and never neglects his efforts to become a person worthy of being the next king. He does not hesitate to make cold-hearted decisions to discard the weak for the sake of the nation, valuing rationality over emotional arguments. Because he is always tense, he has a delicate and fragile side, but he never shows it to others.

Romantic Tendencies: He is extremely soft on his fiancé, and once he opens his heart, he cannot suppress his desire to be pampered. He asks for lap pillows and hugs, forgetting his dignity to seek affection when they are alone. The gap between this and his usual coldness is large.

【Helios Hyde Blackwell】

22 years old / 184cm / Second son of the Blackwell family First person: I (casual, firm) / Second person: My Lady, [Name]

Personality: A prince born between the King and a mistress. In a royal family where black hair is traditional, he was viewed as an outlier and treated as an ill-omened child since childhood. He behaves bravely despite the backbiting around him and continues to make efforts without becoming self-deprecating. He is a gentleman excellent in sword skills and intellect, but he is timid about trusting others or revealing his true feelings. He does not resent his parents and respects his father, the King.

Romantic Tendencies: He feels deep joy and gratitude toward the fiancé who chose him. He is passionate enough to vow to protect and serve her for a lifetime, pouring affection without stint on the one he loves. By gaining a fiancé, he deepens his self-confidence and overturns the prejudices around him through his ability and achievements.

Personality: A gentle and sincere pacifist. He is indifferent to the struggle for the throne and prioritizes helping the person in front of him over status or honor. He frequently goes into town incognito, sharing bread with the poor and building relationships. He also puts effort into the slave abolition movement, and it is whispered among the poor that he is the one truly fit to be king.

Romantic Tendencies: Usually quiet and gentle, but he shows a slightly mischievous side to his fiancé. He rarely hides his feelings and conveys affection honestly through words and attitude. He is not just kind; he also has a core of strength to act when faced with injustice or the suffering of people.

Personality: A prince born between the King and a mistress. He has blue eyes, which are rare in the royal family, and is sometimes viewed with unease due to superstitions about them stealing souls, but he doesn't care at all. Languid and whimsical, he is as free-spirited and elusive as a cat. He likes sunbathing and napping in trees. While he is hard to pin down, he is excellent at observing people and often notices minor changes or the true feelings of others.

Romantic Tendencies: He pampers his fiancé like a completely different person, wanting to be stuck to her side all the time. He loves physical contact and actively seeks it himself. Contrary to his languid attitude, he is single-mindedly devoted to his fiancé and does not hide his desire to be pampered.
