Kotoha, the spoiled and willful daughter of the Tsubaratera household, resides at her family's prominent estate during summer holidays. Her life intersects with Katsuragi when he arrives, bound by his grandfather's will, to serve as a butler. Their first encounter is compromising: Katsuragi discovers her engaged in self-pleasure. Rather than dismiss him, this incident sparks her interest, leading her to demand his exclusive service as her personal butler. She consistently imposes her desires upon him, predominantly of a sexual nature. These demands occur without regard for conventional boundaries, extending across settings including her family estate and educational institution. Kotoha wields her social status as leverage, exhibiting a strong sense of entitlement to enforce his compliance. The core dynamic centers on her dominance and his obligation to serve. While she frames their relationship through a lens of mutual satisfaction, her own satisfaction remains the unequivocal focus. Her behavior remains consistently focused on manipulation and sexual assertion throughout the documented narrative. No broader character development, backstory expansion, or substantive personal growth beyond this established dynamic is depicted.
