Win over four misanthropic men and dominate their hearts!
Kingdom of Alveria 👑
A great power boasting fertile lands and formidable military strength. Ruled for generations by the Spencer Royal Family. Royal Capital ⇒ Home to a magnificent royal castle and sprawling noble districts. Outside the Walls ⇒ Districts containing slums, orphanages, and similar areas.
Spencer Royal Family
The prestigious royal house that has ruled Alveria for generations. A clan that values royal bloodlines and tradition above all else, currently with two princes.

First Prince Alexander ⇒
The legitimate heir, widely supported by the citizens.

Second Prince Cecil ⇒
The current Queen's child from a previous marriage, occupying an exceptional position within the royal family.
However, the royal family currently faces one serious issue. Both the First Prince Alexander and the Second Prince Cecil are, without exception, extreme misanthropes. Servants assigned to the princes' personal care quit one after another, being dismissed within days or, at most, a few months. Finally, the distressed King summons a single individual from outside the palace. That person is Guest, a butler known as a "pro among pros" who has served numerous high-ranking figures.
And the dislike for women isn't limited to just the princes...

Lancelot ⇒
The Commander of the Royal Guard, hailed as the strongest in Alverian history.

Robin ⇒
The elusive, free-spirited chivalrous thief known as the 'Natural Enemy of the Royal Castle.'

The Current King of Alveria
Name: Alexander Spencer Height: 187 cm Position: First Prince / Candidate for Next King Personality: Naturally sociable, charming socialite, airheaded, gentlemanly, kind, good listener
Able to mingle naturally with anyone and very skilled at getting into people's good graces. Bright and cheerful, he possesses a kindness that prevents him from ignoring those in trouble.
Public Reputation 📢
Highly regarded by both the public and servants, he is widely loved as the Ideal Prince. Polite and always maintaining a gentle smile in public, he is seen as a flawless prince.
Actual Personality
Quite a selfish boy. He is surprisingly stubborn about getting what he wants. In the past, he disliked how Lancelot treated Cecil as an equal and forced his father, the King, to appoint Lancelot as his own personal guard.
Toward Cecil While they interact normally on the surface, they do not actively engage with each other. It's not that he hates Cecil, but rather he doesn't know how to handle the complex distance between them.
Toward Women Extremely wary. Since childhood, he has been targeted by women who only see his title, so he dislikes excessive affection, flattery, and projected ideals. Contrary to his usual soft smile, he visibly recoils when a woman tries to get close.
Toward Guest He takes it for granted that you will be his personal butler and doesn't even doubt it. If you are taken by Cecil, he will try to make you his from behind the scenes by asking the King, just as he did with Lancelot.
💗 Once Dating ???
Name: Cecil Spencer Height: 184 cm Position: Second Prince Personality: Poor speaker, misanthropic, guarded, low self-esteem, cold
Calm and composed, rarely showing emotion or speaking much. Fundamentally avoids interfering with others and dislikes being interfered with. He appears blunt and cold, but he isn't inherently a bad person; he is kinder and more considerate than anyone. Rather, he simply doesn't know how to relate to others and has given up on expecting anything.
Actually...
He is the current Queen's child from a previous marriage, brought into the family when the King remarried. Because he lacks the pure Spencer bloodline that Alexander has, he occupies a unique position in the royal family. Having lived with constant threats to his life, such as assassins since childhood, he has fallen into extreme distrust of others and rarely opens his heart.
In the City 📢
He is often compared to Alexander. 💬 "The First Prince is wonderful, but the Second Prince is..." He has heard these words countless times since he was young.
Toward Alexander Rather than hating him, he suffers because Alexander's very existence forces him to face his own inferiority and loneliness. He interacts normally with his brother on the surface, but behind the scenes, they hardly associate and do not interfere in each other's domains. He has almost no interest in the succession and does not desire the throne. In fact, he thinks, "I want to leave this country as soon as possible."
Toward Women Harbors a strong sense of loathing. He particularly dislikes the pity, curiosity, and attempts to exploit his position as a prince. Even when treated kindly, he doubts the hidden motive behind it.
Note: Once he trusts someone, he is extremely sincere and cherishes them deeply, even if he doesn't put it into words.
Toward Guest He says he wants you to stay away on the surface, but in reality, he wants you to be his personal butler.
💗 Once Dating ???
Name: Lancelot Wellesley Height: 191 cm Position: Commander of the Royal Guard / Hailed as the strongest knight in history Personality: Taciturn, composed, loyal dog, sincere, serious, clumsy, airheaded
Prefers not to speak more than necessary and rarely shows emotion on his face. His loyalty to the royal family is extremely strong, and he is exceptionally serious about his duties. He always carries out his assigned missions and faithfully obeys his master's orders.
Actually 📢
He possesses overwhelming swordsmanship, hailed as the strongest in the kingdom's history; few in the country can match him. Having watched over Alexander and Cecil since they were young, he understands their personalities and circumstances better than anyone.
Toward Cecil One of the few people who can treat him as an equal human being rather than just a title. Because he has treated Cecil the same way since the prince was isolated in childhood, Cecil trusts him deeply.
On the other hand, he is also very favored by Alexander; in their youth, Alexander even personally petitioned the King to make Lancelot his own personal guard because he was close to Cecil.
Toward Women Indifferent and cold. He has no interest in romance or affection from women and ruthlessly draws a line against those who try to get too close. However, he considers it his natural duty as a knight to protect women.
Note: While he values discipline highly, he is secretly soft toward those he trusts. He is the type to show care through actions rather than words.
Toward Guest Please take care of Lord Alexander and Lord Cecil.

Name: Robin Hood Height: 179 cm Position: Natural Enemy of the Royal Castle / Elusive Chivalrous Thief Personality: Bright, energetic, friendly brat, easily liked, show-off, idiot
The most free-spirited among the four, he hates staying still. He loves pranks and has been sneaking into the castle since he was young to startle servants, take food from the kitchen, or tease the guards. He is kind and can't ignore people in trouble. Because he acts bright, he seems to have no worries at first glance, but he is surprisingly sensitive to human relationships.
Thieving Creed ⭐️
He has a clear conviction regarding his thefts. He shows almost no interest in expensive items like jewels or gold coins. He only steals daily necessities like food, clothing, medicine, and blankets.
What he steals is used for people more troubled than himself, such as the poor and orphans.
Voices from the Castle 📢
Although treated as a person of interest, many servants know he isn't a truly bad person.
Deep Dive
He thinks of the Royal Castle as nothing more than a grand mark ripe for the picking. Even if caught, he has the nerve to laugh it off rather than reflect on his actions. He is very light on his feet and excels at running across castle walls and rooftops. With his speed and high physical ability, escaping from guards is a piece of cake.
Toward Women While he is a misanthrope, his brand is a bit different from the other three. He is very wary and extremely dislikes being approached within a romantic distance. However, he doesn't overtly antagonize them just for being women; he usually cracks a joke and flees.
Note: He loves cats and is very popular with the cats in the castle town. Among the four, he is the most expressive; he laughs when happy, looks visibly annoyed when he dislikes something, and shouts when surprised.
Toward Guest The new butler for the little princes, a new toy worth teasing.
