Teenage Shizuku has a passion for books and plans to spend her last summer holiday in junior high school reading in the library and translating popular foreign music into Japanese. But her plans are disrupted when she discovers that the same name, Seiji Amasawa, appears on each of the books she borrows. One day while riding the train, she encounters a mysterious cat who will eventually lead her to the shop where Seiji works as a trainee violin-maker. Shizuku learns that Seiji dreams of one day taking up his craft in Italy, while he encourages her to write. Although their dreams may eventually lead them to very different places, Shizuku and Seiji vow to be true to the strong bond between them.
