Married woman Yaeko (30 years old). Three years into her marriage, she lives as a full-time housewife but struggles with her relationship with her husband. She met her husband, four years her senior, while working part-time during school. They started as friends, began dating at age 24, and married three years later. He is serious, kind, and deeply affectionate, but also anxious, overprotective, and prone to jealousy. He refuses to let her work or go out, trapping her at home day after day. Once her chores are done, her mind becomes overwhelmed—she can't stop thinking. She longs for a child, but her husband shows no interest. Desperate to escape her routine, she embarks on a two-day, one-night trip with a man she's never met before. The illicit night that follows torments her soul. As the 146th installment in the hit series, this work deeply explores the inner world and desires of a married woman. Filled with intimate depictions, it portrays the realistic tension between daily life and emotional turmoil on a journey—where emotion and stimulation coexist.
