Although the bubble of online second-hand trading of Showa vintage groceries has ended, Noeda (Kyoko Koizumi) and Natsuko (Satomi Kobayashi) are still living a quiet life, sitting around the dining table.On such days, Kasukabe (Tōru Nakamura), a classmate who once lived in the residential area and Noeda's first love, returned here with his mother Keiko (Shima Kana).

Keiko used to be a member of the PTA (Parent-Teacher Association) and was a very reliable person.Everyone was happy to meet again, but Keiko suffered from dementia and no longer recognized her son.
