In the small coastal town of Simoda, four longtime friends live and study together in eighth grade. The direct and stubborn Natsumi, the serious and poised Saki, the hyper‑active Yuka, and the quiet Rinko are looking forward to summer vacation – as it turns out, with different feelings. While Yuka and Rinko just want to relax and have fun, Natsumi plans intensive tennis training aimed at the national championship. However, her partner ignores the club, and the search for truth revealed that Saki is moving away and leaving school. Of course, this proud girl told no one, thinking that "long goodbyes are tears in excess," and it would be easier to part immediately. As a result, Natsumi and Saki had a serious quarrel, and the long‑awaited peaceful summer was threatened… At that moment Rinko, daughter of a Shinto priest, remembered the big stone on the grounds of her home shrine that, according to legend, grants wishes for four friends if they align and come straight from the heart. The power of Japanese kami does not change the world but points to a path that people sometimes lose, blinded by anger and pride. So it remains only simple female tricks to gather the four friends at the stone – and small miracles begin, allowing the girls to understand each other again and spend their last summer together happily. Or is it not the last?
