Miku lives a life of rigid routine, trapped in a marriage where her husband ignores her physical needs and prefers predictability over passion. Left to her own devices, she finds herself sneaking into the kitchen late at night to masturbate, desperate to release the sexual tension that has built up over years of neglect. Her quiet, lonely existence is suddenly disrupted when her father-in-law arrives, seeking refuge after a falling out with his wife. This man has always made Miku uncomfortable, often leering at her with predatory eyes and making inappropriate comments that her timid husband is too afraid to challenge.
One evening, the father-in-law catches Miku in the middle of her nightly ritual, witnessing her vulnerable state in the kitchen. Recognizing her deep-seated frustration and the lack of intimacy in her marriage, he decides to take matters into his own hands.

As the encounter unfolds, Miku finds herself caught between her moral hesitation and the overwhelming physical release she has been craving. Her husband eventually notices a change in her demeanor and attempts to stand up to his father, demanding he leave their home. However, the damage is already done, and the secret intimacy shared between the father-in-law and the daughter-in-law has forever altered the dynamic of their household. This intense scene explores the boundaries of familial relations and the consequences of a neglected marriage, delivering a raw, dramatic performance by Miu Shiromine.
