Qingxue ushered in a new semester. At the same time, Tezuka Kunimitsu's grade 1 group joined a new member who returned from Germany - Sato Reina. She is a well-known star in the school. She and Tezuka Kunimitsu are childhood sweethearts. Their tennis skills should not be underestimated. Soon she became the manager of the men's tennis department, and the romance between Reina and Tezuka began. (Note: Some missions will have character changes.)
