## Synopsis

Aina Takigawa stars as a sister whose calm, everyday life is shattered by an abrupt transition. When her brother pretends to make a mistake during an intimate moment, Aina’s unresponsive attitude is replaced by a sudden, intense physical reaction. The film focuses on her losing herself in the moment as the encounter becomes relentless. Ignoring her initial reactions, the focus shifts to her single goal of physical surrender in a series of scenes that just don't stop. The production captures her transformation from a composed sister to a woman overtaken by an obsessive need to be filled up.
