Ichika was troubled by the lack of intimacy in her marriage. Her husband was busy with work and had low libido, so they rarely had sex. They didn't have children yet, but their relationship remained stable. She had fallen in love with his kindness and his intense focus on whatever he pursued, which is why she decided to marry him. Ichika was modest and hardworking, faithfully fulfilling her role as a devoted wife. However, she deeply enjoyed sex and had been secretly cheating on her husband with different men each day, careful not to get caught. It had become as routine as wearing jeans every day—her casual, repeated affairs had trapped her in an almost addictive compulsion. Though she knew it was betrayal, she couldn't stop. Each affair she piled up reflected the deep, hidden darkness within her soul.
