Katsuragi, a dutiful young man, reluctantly takes a summer position as a butler at the Tsubaratera estate to honor his grandfather’s final wishes. Tasked with managing the household’s needs, he becomes the primary attendant to Kotoha, the estate’s capricious heiress, whose provocative teasing gradually blurs the lines between professional duty and personal entanglement. His earnest nature clashes with her unpredictable demands, unwittingly entangling him in a charged power struggle that challenges his reserved demeanor. Motivated by a desire to avoid imposing on his family, Katsuragi embraces servitude as both obligation and escape. His naivety in matters of intimacy becomes apparent as mutual curiosity sparks tension between him and Kotoha, complicated further by Mine, a determined classmate whose aggressive advances force him to acknowledge his conflicted emotions. Over time, Katsuragi shifts from obedient caretaker to assertive confidant, questioning the rigid hierarchies defining his role. His journey peaks when Kotoha dissolves their employer-servant dynamic, demanding a relationship built on parity rather than tradition. This pivotal decision underscores his resolve to redefine self-worth beyond societal constraints, bridging divides of class and expectation. Katsuragi’s evolution navigates the interplay of autonomy and vulnerability, testing his adaptability amid conflicting desires. While his interactions with Kotoha and Mine probe themes of agency and control, the narrative balances these complexities with a playful tone, framing growth through candid emotional encounters rather than solemn reflection.
