After being abandoned by his family in the middle of the night, a high school student finds himself homeless and at a loss. His classmate, the extremely introverted and wealthy heiress Amamiya Shizuhisa, offers him a live-in position as her personal butler. Shizuhisa has always been a wallflower, too shy to trust or approach anyone, and struggles with her lonely school life. The protagonist accepts the job and begins attending to her daily needs, gradually doting on her with small gestures of kindness and care. To his surprise, Shizuhisa starts to open up and becomes deeply attached to him, revealing a clingy and affectionate side that contrasts sharply with her usual gloomy demeanor. Their relationship develops from a formal master-servant dynamic into a sweet, mutually devoted bond. The story unfolds primarily within the walls of Shizuhisa’s mansion and their high school, following episodic slices of life including their first meeting, horror movie nights, fashion outings, Halloween pranks, and Christmas celebrations. Each event draws the two closer together and showcases Shizuhisa’s gradual transformation from a withdrawn young lady into a smiling, love-struck girl who unabashedly expresses her feelings. The narrative balances gentle humor with heartwarming domesticity, focusing on the growing intimacy between a half-baked butler and an emotionally starved heir. A parallel serialization, My Pure Lady, later expands the same premise into a black-and-white episodic format featuring additional seasonal stories.
