I've never had sex with anyone other than my favorite person so far," said Chitose Hagawa, 55. Currently, Chitose, who lives as a full-time housewife surrounded by her husband, who has been married for 28 years, and their two children, is actually a trilingual returnee who can speak English and Italian. Before marriage, she worked as an in-house interpreter for a major corporation utilizing her language skills. "My husband is a Japanese person from the overseas branch of the same company..." Even after marriage, feeling lonely due to her husband's frequent travels between Japan and overseas, she secretly made a boyfriend. However... "After breaking up with that boyfriend, whom I had been with for 15 years, I couldn't find the next one." Although she had longed for free sex, Chitose, who had never been able to take that step until now, sets out on a new journey at the age of 55.
