Last year, Ami married a man much older than her. Her husband was always kind and considerate, genuinely caring for her well-being, but Ami harbored a secret. She was having a physical relationship with Akira, the young man living in the apartment next door. As Akira came over to Ami's place as usual, their affair grew even more intense. While keeping her secret from her husband, Ami continued her daily life entangled with Akira.
