Starting her school life in first grade, Shiori confronts the topic she had heard frightening gossip about—homework! Yet her unease quickly transforms into enthusiasm when the Asahigaoka girls decide to collaborate on their tasks at Komari and Natsumi Koshigaya's residence. Their scheme seems to work until a familiar urge to delay turns into a noisy distraction for Natsumi.
On another occasion, Natsumi requests her instructor Kazuho Miyauchi to establish and head a fresh badminton club at school. Although insufficient funds and gear pose a significant obstacle, Natsumi and the other girls still approach candy shop proprietor Kaede Kagayama for assistance. While they practice badminton on a whim, a small mishap prompts Kaede to recall an unforgettable day she spent babysitting Renge Miyauchi. Their shared laughter echoed through the hallway, reminding them that teamwork could transform challenges into cherished memories everywhere today.
