Nowaki, three years into her marriage, was forced into an arranged marriage due to her strict parents' influence, even after reaching adulthood, having previously been separated from a lover. Though she felt doubts about living with a husband she had no affection for, she passively accepted it as mere dissatisfaction. However, one day, she lied to her husband, saying, "We don't have children yet. In fact, we're using contraception," and left home. From her first encounter with another man, she immersed herself in a warm, soothing hot spring and experienced pleasure she had never received from her husband. In that moment, she truly felt the joy and liberation of being a woman.
