Nakamura met a charming woman with long, black hair. Before marriage, she worked as a career woman at an advertising agency, but after marrying her husband who runs an IT company, she became a full-time housewife. Driven by her dream of becoming a housewife, she chose marriage, and on the surface, her life appeared fulfilling. However, after the wedding, her husband's attitude changed drastically, becoming cold and indifferent, like a completely different person, leaving Nakamura feeling lonely every day. Their conversations grew scarce; even when she prepared meals, he would eat in silence. She changed her hairstyle, but he didn't notice or show any interest. Amid this emotional neglect, Nakamura began harboring dissatisfaction, and somewhere along the way, the temptation to cheat started to grow.
