In middle school, Run and Tora were almost inseparable, but a one‑class difference caused them to practically part for an entire year when Run entered high school. The cheerful and spontaneous Run didn"t miss anything, while the determined little Tora clenched her teeth and prepared for exams to get into the same school, Aoygoka. Finally, the happy younger friend ran to her older sister"s house to deliver good news—and found Run in a room with two completely unfamiliar girls. That"s one thing, but what was one of them doing with the room"s owner on the bed?! It turned out that in the new school, Run had become close friends with the tall, striking Yuko and the glasses‑wearing scholar Nagi. There is enough room in everyone"s heart for all of them—this is the kind of wisdom women learn that schools don"t teach, but those gathered have plenty. You can be clumsy, not excel in academics, or daydream—just don"t abandon those you care about. Run set the idea, Yuko and Nagi supported it, and pulled the unsmiling Tora into their circle—ultimately the friendly group slowly but surely grew to four girls, whose lives and adventures we will now follow on screen. Truly, the spring season is rich with stories of beautiful everyday life!
