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 together was their first time walking outside in four years. Despite being fiancés, they felt a strange tension, and conversation didn't flow easily. But the moment they entered their home, they embraced each other like a breaking dam. "I've been waited for you... I've wanted to do this for so long..." They fucked frantically to reclaim the four lost years.
