Two opening chapters return to the day of Kousei Arima's first performance after Kaori Miyazono pulled him back to the piano, revisiting that turning point from other angles. From there the collection hands its remaining stories around the cast: Emi Igawa's school life and the secret society she is mixed up in, a chapter set two years later that catches up with Nagi Aiza and Koharu Miike, and a closing piece that returns to what Kaori was carrying that summer. Bundled with the anime's home video release, these five short stories fill in corners the main series skipped past.
