Nana and Wataru had just gotten engaged and moved into a new home, with their wedding just around the corner. However, Wataru was falsely accused of professional embezzlement and sentenced to four years in prison. Four long years passed. Nana waited faithfully for Wataru, and the day of his release finally arrived. As she welcomed him home, the walk back... it had been four years since they last walked together. Despite being fiancés, they felt a strange tension, and conversation didn't flow easily. Once they reached home and entered the doorway, they embraced each other like a broken dam. "I've been waiting for you... I've wanted to do this for so long..." They fucked with single-minded devotion to reclaim the four lost years.
