Since the family moved to Tokyo, Shinichi has been busy studying so he has not had the opportunity to return to his hometown to visit his grandparents. During this year's summer vacation, he decided to return to his hometown for a while. As soon as he entered his grandparents' house, he met a charming girl. It turned out that it was Yume, his neighbor, who was very close to him before moving to the city. After many years of meeting again, Yume is still as cute as ever but her body is extremely "mature". Yume is currently working for an insurance company. Her father's health is not good so she doesn't want to move to the city. Yume has always taken care of and visited Shinichi's grandparents. That night, the four of them ate together and talked to each other. Shinichi also shared that he had a girlfriend, and his grandparents were extremely happy and wanted to meet their grandson soon. The next day, Yume's manager came to sign an insurance contract with Mr. and Mrs. Shinichi. Suddenly, Shinichi witnessed that Yume was the baby daddy of that department head, but it seemed like she wanted to end this relationship. Yume also knows that Shinichi often peeps at her body, so she lets him enjoy her freely. The two continuously indulged in sensuality during the time Shinichi stayed here. And it's time for Shinichi to return to the city. The same scenery, the same people, many years ago, Yume held him back, forcing him to promise to return. But it seems that Shinichi is different now, he can no longer recognize the feelings that Yume sent him...
