Kaori (pseudonym) is a 28-year-old newlywed woman living in Setagaya Ward. After graduating from a women's university, she was hired by a major preparatory school and currently works there as an instructor. She has no dissatisfaction with her husband, but rather feels anxious about how the institution of marriage gradually strips women of their freedom. She says the reason she signed up for an affair trip was because she thought, "If I continue living my life as a housewife, I might regret it in the future." She isn't seeking luxury hotels or hot springs—her sole motivation is the desire to experience a lewd and thrilling journey, which led her to make this bold decision.
