Spring, the season of encounters and partings. It's spring break, and Sakawa Haruki is about to go into 3rd grade.
His childhood friend group includes: Kuriyama Tomari, Tokorozawa Iku, and Sugou Chisato. 2 new girls just joined the group: Harunohara Yuuna, who lives in the next town over, and Nishitani Shizuru, who just moved into the neighborhood.
Ironically, at the same time these 2 girls joined, Haruki had to move away from home and his childhood friends.
