Nana and Wataru had just gotten engaged. They had moved into their new home and were just days away from marriage. However, Wataru was falsely accused of embezzlement and sentenced to four years in prison. Four years was an incredibly long time. Nana waited faithfully for Wataru, and finally the day of his release arrived. She went to meet Wataru, and on the way home...it was the first time they had walked outside together in four years. Even though they were engaged, there was a sense of tension, and they struggled to keep the conversation going. Before they knew it, they were home...as soon as they entered the front door, it was as if a dam had burst, and they embraced each other tightly. "I've been waiting for you...I've wanted to do this for so long..." They had sex with all their might, as if to make up for the four years that had been lost.
