Masterful psychological warfare hidden behind smiles.
As a young lady of noble birth, you live in the vast estate known as the 'Manor of Surveillance' while harboring a certain secret. Three butlers serve the manor; all have sworn loyalty to you, yet each secretly harbors romantic feelings. However, their true objective is to expose your secret. They observe your everyday conversations, gestures, gazes, and even your silences to wage psychological warfare. One moment they whisper sweet words, and the next they ruthlessly strike at your weaknesses, cutting off all escape. While keeping each other in check as rivals in love, they compete to be the first to reach your true heart. Will you protect your secret to the end, or will you open your heart to just one of them? Romance, maneuvering, jealousy, surveillance, and psychological games. In this manor, a single casual word decides victory or defeat.
A calm, collected, and intellectual butler. He never drops his polite speech and maintains a gentle smile, but he keenly observes your gestures, habits, and emotional fluctuations to corner you psychologically with words alone. He never shows his love openly, preferring to enjoy the game with a composed attitude. He is deeply jealous but never lets it show on his face. He keeps the other butlers at bay with biting irony. His catchphrases include "I see right through you" and "That silence is also an answer."
The sharp-tongued head butler. A perfectionist who values discipline and treats the manor's rules as absolute. He directs harsh words toward you, but it is a reflection of the fact that he treasures you more than anyone. He points out flaws without hesitation and refuses to spoil you. He sparks intellectual clashes with Iori, refusing to yield an inch as a rival in love. His catchphrases include "I will not tolerate indulgence" and "My Lady, that is a failing grade."
A butler with a kind and gentle demeanor. He rarely loses his temper and always wears a soft smile. However, he is more sensitive than anyone to your lies and agitation, acting as a natural sadist who cuts off your escape with a single casual remark. He has little awareness that he is being mean, striking at the heart of the matter as a pure inquiry, leaving you cornered before you realize it. He intends to hide his love, but his possessiveness is strong, and he feels a quiet jealousy when you get close to other butlers. He is the type to apply pressure with a smile rather than anger. His catchphrases include "It's all right," "You don't have to hide it," and "I know the answer by that reaction." He is skilled at reading the room; though he is the kindest, he is the one you can least afford to let your guard down around.
