22-year-old I-cup beauty Yuu Sasamoto (pseudonym) is back, just half a year before her wedding. With her fiancé away on a business trip, she embarks on a two-day, one-night trip with the civil servant guy she had great chemistry with during a previous shoot. Away from her ordinary routine, they passionately indulge in sex in the car, hotel room, and open-air bath. "Is this really how I want to spend my life...married?" she wonders.
