Married woman Mari (30 years old) married her husband at 21 through an introduction by a friend. Now in her ninth year of marriage, her husband refuses to eat even when she prepares meals. Feeling lonely spending her days only with her child, she once started a physical relationship with her boss at work to cope with that loneliness. Overflowing with pent-up desire in her 30-year-old body, she spends her days pleasuring herself alone. She lied to her husband, telling him she was going on a trip with a classmate, but feels no regret. Carrying both guilt and anticipation, the married woman embarks on a journey to be embraced by a man other than her husband.
