こないだおばさんって言われたよ

54-year-old Mikawa Meiko is a single woman who quit her office job to run a small donut shop. One night, she picks up a wallet that has fallen at her feet and takes it to the police station, but the handsome young man who owns it says, "Thank you, Auntie," and she is shocked by the power of those words. Faced with the reality of being an "auntie," Meiko confronts one wall after another of "aging."
