Only two people remained in the deserted town cheering for the national tournament. Kasumi Tsukino got fired up and had an affair with her ex-girlfriend, who is now a married woman, for three days.
When I returned home for the first time in a long while, I learned that my local school's baseball team had made it to the national tournament, and all the residents were staying overnight to cheer them on. Only I, the director's wife, and Kasumi, who can't fit in, remain in town. Kasumi is an ex-girlfriend from her school days, and while she feels awkward about meeting her again after such a long time, they are reminiscing about old stories while visiting the grounds and bus stops that remind her of her school days, and her faint feelings are rekindled...A limited-time offer where summer monsters stir your heart. An affair begins. During the summer in the countryside, where there was nowhere to play, the two had too much time to spare, so they piled on each other over and over again until the residents returned home.
