Mashiro Aoi (Ayase Haruka) lives with her son in housing constructed in Ishinomaki City, Miyagi Prefecture after the Great East Japan earthquake. She appears to have bounced back and lives cheerfully. But she actually keeps waiting for her husband Takatomi (Kora Kengo) who has been missing since the tsunami hit Ishinomaki City. At that time, both the bookstore that Takatomi and her mother-in-law Asako (Agawa Sawako) had been running and their house were swept away. That plot of land was designated a disaster area and Aoi could not return. It has been almost 10 years since then. Aoi decides to renovate a vacant house in town and reopen the bookstore that Takatomi loved with start-up capital she had steadily saved up and the books she had bought again.

Eiki is a socially awkward architect who moved to Miyagi Prefecture in search of a place where he can be himself,
