Shizuku lives a simple life, dominated by her love for stories and writing. One day she notices that all the library books she has have been previously checked out by the same person: "Seiji Amasawa."

Yoko, a 5-year-old girl, on a walk with her father finds an abandoned Western-style building with a beautiful garden, into which an elderly woman is moving. Yoko is attracted to the noisy grandmother, although she is afraid. Eventually Yoko falls ill with diphtheria and spends her time in the hospital. One night she is guided by a girl, who looks into the mysterious world of her grandmother's memory. The memories of 5-year-old Yoko and her 70-year-old grandmother overlap. Yoko experiences an adventure in her grandmother's time that was neither her dream nor reality.
