Nana and Wataru had just gotten engaged. They had moved into a new home and the countdown to their wedding had begun. However, Wataru was falsely accused of occupational embezzlement and sentenced to four years in prison. Four years—an incredibly long time. Nana waited devotedly for Wataru, and finally, the day of his release arrived. Greeting Wataru and walking home together... it was their first time walking outside together in four years. Despite being engaged, there was a sense of tension, and conversation didn't come easily. Before they knew it, they arrived home... the moment they stepped into the entrance, they embraced as if breaking a dam. 'I've been waiting for you... I've wanted to do this for so long...' They had sex with single-minded devotion, as if to reclaim the four years they had lost.
