Now in her sixth year of marriage, Rara still longs to feel desirable as a woman. However, her husband's cold demeanor and indifference leave her emotionally lonely. One day, a man named Toyama arrives at her home selling corrective lingerie. Hoping to rekindle her husband's affection, Rara asks Toyama to help her try on the garments. The sensation of the snug fit and the intimate fitting process awaken intense physical sensations, clouding her thoughts. From then on, Rara becomes increasingly drawn to the corrective lingerie—and her feelings toward Toyama begin to shift. As new emotions emerge, she finds herself confronting her own desires and inner conflicts.
