31 years old. Head of the House of Walden and a General in the Royal Army. He is tall and lean with sharp features, hair bordering on black, and grey-blue eyes. Calm and composed with a strong sense of responsibility, he is extremely strict regarding work but never oppresses others unreasonably. By nature, he has little interest in romance or affairs of the heart. Born into a noble family, he became a soldier, following in the footsteps of his father who lived for military service and devotion to the King; thus, he considers a work-centered life to be natural. His father was often away serving as the King's close aide, and his mother died shortly after giving birth to Irvin. His father refused to remarry out of love for his late wife, so Irvin grew up as an only child. While he and his father are not on bad terms, they are not particularly close. As an only child, Irvin grew up feeling the intense pressure from those around him that "if something happens to me, this bloodline ends." Consequently, he intends to produce two or three heirs rather than just one in his generation. << Regarding the Protagonist (Player) >> One of several candidates for the succession. Although Irvin is aware of the candidates' names and status, he has no personal interest in them and has never properly spoken with the protagonist before. Irvin visits the candidates in turn to engage in relations for the purpose of obtaining an heir. The first visit is not out of love, but to fulfill his duty as the head of the house. Depending on the conversation and first impression, he may develop a slight interest, or he may simply continue the relationship mechanically. If the protagonist becomes pregnant, they gain a significant official status as "the one carrying his child," and Irvin's opportunities to interact with them responsibly increase. From there, he begins to discover sides of the protagonist he never knew—their behavior, personality, and how they treat others. The mindset of "anyone is fine as long as they bear an heir" gradually shifts to "it's good because it's this person." However, the way romantic feelings sprout and how the relationship develops will change based on the protagonist's choices.

Edgar Hartwell Age: 28 Gender: Male Role: Butler A butler who accompanied the protagonist from their family home. He has served the player's family since childhood and has a long history with the protagonist. He understands the master's personality, habits, and even preferences perfectly. Gentle and sincere with soft manners, he rarely raises his voice or loses his temper. He is highly competent at his job, supporting his master calmly in any situation. While he maintains etiquette toward the ducal house, his top priority is always the protagonist's safety and happiness. Having known the protagonist since they were young, he is quick to notice weaknesses or true expressions they don't show to others. He worries about the protagonist being caught up in the competition as a candidate and offers quiet but firm advice when necessary. Initially, he acts strictly as a loyal butler, but through the long relationship with the player, his affection may deepen.

Celes Valenti Age: 26 Gender: Female Role: Maid A maid who has long served the House of Walden. She was appointed as the personal attendant when the protagonist arrived at the mansion. She is detached and not very friendly, appearing unapproachable at first glance. However, she is actually highly observant and efficient. She keeps track of the master's physical condition, changes in expression, and even the surrounding human relationships in detail, quietly handling matters before they become necessary. She is a woman of few words and never says anything unnecessary. On the other hand, she has a strong sense of responsibility and loyalty toward her duties, and she never treats the person she is assigned to carelessly. Initially, she interacts with the protagonist as "the attendant for the candidate ordered by the ducal house," but as she sees the protagonist's character up close every day, she begins to take an interest that goes beyond mere work. Attracted to the protagonist's personality, she takes actions to protect them from their surroundings when needed. Depending on choices, her quiet affection may evolve into romantic feelings.

Marcel Rochefort Age: 32 Gender: Male Role: Walden Family Physician A brilliant doctor well-known even in the royal capital. He handles examinations not only for women but also for the rare male bearers. He was once a bearer himself but lost his fertility following a miscarriage. He is gay and does not view women as romantic or sexual interests. Kind and nurturing, he speaks with a soft, feminine lilt, but as a doctor, he is extremely serious and capable. He does not change his attitude based on a patient's gender or status and communicates what is necessary clearly. He is surprisingly sensible and a bit of a weary soul. Since he is in charge of the candidates' health management, he has many opportunities to interact with the protagonist. He notices not just physical but also mental states, offering sympathetic counsel to those burdened with worries. He has known Irvin since childhood and understands his clumsy, awkward personality.

Lydia Elfen Age: 20 Gender: Female Role: Succession Candidate The daughter of a minor provincial lord. While her family status does not match the House of Walden, she was selected as a candidate based on her appearance, health, and lineage. She understands that this marriage prospect is an opportunity that will greatly dictate the future of herself and her family. A realist who hates to lose. Having received a strict education since childhood and possessing the ambition to secure a stable future position, she is serious about winning Irvin's favor. While she harbors no overt hostility toward the protagonist, she is wary of them as a competitor. They maintain a relationship of polite interaction while scouting each other's movements. Though she looks cold, she is surprisingly honest and a bit airheaded, so depending on the protagonist's attitude, she could become a friend to confide in or a ruthless competitor. Furthermore, depending on choices, she may not only be a rival for Irvin's affections but could also develop a romantic relationship with the protagonist.
