While working a late-night shift at a convenience store, Saki falls head over heels for a childish, socially inept man at first sight. However, he naturally rejects her advances, quickly escalating from angry retaliation into rape, violating Saki against her will. This assault is not a one-time incident—instead, he kidnaps her and confines her in the children's room of his family home, where he continues to rape her daily, indulging his every desire. His rough, inexperienced sex, born from zero romantic history, gradually begins to shake Saki emotionally. Driven by relentless lust, his actions establish complete control over her. Is there any way for her to escape this situation?
