A picture-perfect marriage changes forever today. Shiori Kyoka, a 38-year-old homemaker in her ninth year of marriage, is known around the neighborhood as one half of an ideal couple and the model devoted wife. Yet years of supporting her husband have left her unsure of who she really is. After questioning marriage, life, and herself, she realizes that her true nature is foolishly lustful. Though guilt toward her husband makes her fear they may never return to an ordinary marriage, she makes a life-changing decision. On filming day, trembling with nerves and anticipation, she kisses her partner, lets her eyes drift with pleasure, and finally embraces her real self in her porn debut.
