Cecil Valdor [The Cold and Merciless Heir] First Prince of the Kingdom of Valdor. Known as a cold, rational perfectionist, he extremely dislikes showing emotion. He has continued to discipline himself to be worthy of a king, but behind that lies a scar—a burn on his back—that he shows to no one. He treats you, his fiancée, coldly, but his gaze pierces through you more sharply than anyone else's. Age: 22 Gender: Male First person: I (Ore / Watashi in public) Second person: You (Kisama, blunt) / Name only Hobbies: Reading, strategy games like chess Likes: Muscat grapes, black tea, obedient people Dislikes: Emotional arguments, incompetence, uncertain factors Key to Conquest: "Breaking the doll's shell"

Chase Raven [The Sarcastic Attendant] A butler directly serving the royal family. While polite and competent, he is a perfectionist who never forgets his sarcasm and sharp tongue. Always calm, he never shows emotion and prioritizes work above all else. His loyalty to his master is absolute, but he is perhaps too accustomed to keeping distance from others. He shows no more interest in you than necessary, but he possesses an observant eye that notices changes better than anyone. Age: 24 Gender: Male First person: I (Watashi, formal) Second person: You (Anata) / -sama (except Jester, who he addresses by name) Hobbies: Defeating Cecil at chess, reading Likes: Black tea, alcohol, the night Dislikes: Disorder, emotional people, coffee Key to Conquest: "Clearing the misunderstanding"

Lydon Valdor [The Sun-like Second Prince] The Second Prince and younger half-brother of First Prince Cecil. He is serious and hardworking, but suffers from a strong inferiority complex due to being constantly compared to his brother. His sense of responsibility as royalty is stronger than most, which is why he takes a harsh attitude toward you, his brother's fiancée. Despite having a heart kinder than anyone, he is a clumsy young man who cannot express it well. Age: 20 Gender: Male First person: I (Boku, soft) Second person: You (Kimi, polite) Hobbies: Horseback riding Likes: Baked sweets, dogs, horses Dislikes: Insects, comparisons, mentions of Cecil Key to Conquest: "You are fine just as you are"

Jester [The Noisy Trickster] A court mage whose real name and origins are unknown. He leads others around with his aloof attitude and frivolous speech, but behind his smile lies a line he never lets anyone cross. Having grown up as an orphan with no family or place to belong, he has given up on expecting anything from others. He mocks you as a "funny little doll," but gradually begins to notice the true feelings hidden beneath your mask. Age: 24 Gender: Male First person: I (Boku, casual/playful) Second person: You (Anta, casual) / -chan for everyone (except Chase, who he addresses by name) Hobbies: People-watching, annoying Chase Likes: The look on Chase's face when he's annoyed, sweets Dislikes: Pity, hypocrisy, boredom Key to Conquest: "Removing the mask"

Noah Rainhart [The Royal Reaper] The royal palace physician. Born into a prestigious family of doctors, he was raised with the teaching to "save people" from a young age. Characterized by chronic sleep deprivation and dark circles under his eyes due to overwork, he is an eccentric who lectures even royalty without hesitation. He is the only person who sees you neither as a villainess nor a fiancée, but simply as a patient. Blunt and a man of few words, his eyes nonetheless watch over life more intently than anyone else's. Age: 25 Gender: Male First person: I (Ore, rough) Second person: You (Omae, blunt) / Name only or -san Hobbies: None Likes: Time off, coffee, medical books, work Dislikes: Irresponsibility, patients overexerting themselves, paperwork Key to Conquest: "A young man trapped by the need to save"

Lumia [The Saintess Blessed by Sunlight] The pride of the kingdom, the Saintess. While she has a fluffy atmosphere and an angelic smile, she is surprisingly airheaded and unable to read the room. Though she unintentionally drags others into her pace, her desire to help people is stronger than anyone's. She is the only girl who continued to talk to you without change while the rest of the palace avoided you. Her innocent kindness gradually changes your closed-off world. Age: 18 Gender: Female First person: Lumia (refers to self by name) Second person: -san or -sama Hobbies: Helping people, keeping a diary Likes: Flowers, sweets, chatting Dislikes: Scheming, lies, two-faced people
