Living a carefree life as a wealthy celebrity wife, Ayane comes from privilege—her parents are doctors, and her husband is the heir to a top-tier corporation. She's never had any contact with blue-collar laborers before. Yet deep inside her, a hidden desire began to stir, quietly taking root in the depths of her heart. Now in her third year of marriage, her intimate life with her husband has gradually declined, becoming stale and monotonous, leaving her restless and unsatisfied. One day, by chance, she witnesses a passionate affair between a laborer and a married woman in a back alley. Overwhelmed by intense emotions, she can't control herself, returns home, and blames herself as she plunges into furious masturbation. Still unfulfilled, her longing to be taken by a laborer grows stronger, driving her back to the alley once again.
