The 109th installment of the hit series featuring married woman Kayoko (38). Married for three years, no children. Her husband is a coworker of the same generation. As those around them gradually married, the two naturally grew close. Raised under strict parents, they quickly empathized with each other due to their similar backgrounds. After marriage, they left their parents' homes and experienced freedom for the first time—yet as a couple, they found no freedom. Harassed by the husband's overbearing mother, they live each day under constant surveillance. Feeling trapped with no hope of freedom, desperate Kayoko plans a two-day, one-night getaway with a complete stranger. Escaping reality, she abandons her beloved husband and unleashes her mind and body in a night of intense liberation.
