Yumiko Sakura, 50 years old, a full-time housewife.After 25 years of marriage, she had a second son with her husband and lived without any particular inconvenience, but her marital sex life has completely cooled down. She says, "Not only is there no sex... my husband is just a housemate, but that's what 'family' is all about..." She has cheated. More than 10 years ago, she was invited by her friend to go to a happening bar for the first time. "I was scared at first, but the atmosphere, or rather the stimulation, made me so excited that I wondered if it was really me."
