A friend request with a lost love sends a man back into his memories of the ’90s, when life seemed to burn a little brighter

Natsuko Kotani was born to be a swindler. Meanwhile, Tetsuko Ishida is Natsuko’s distant relative. Unlike Natsuko, Tetsuko is an attorney with an upright disposition. Whenever Natsuko makes trouble, Tetsuko is called to solve her troubles. Believing that Natsuko is using her, Tetsuko, with her boring life, begins to change.

Following the death of the unmarried and childless Taki, Takeshi, a young relative of hers, discovers several pages of closely written lines in which the old lady has recorded her memories. This is how he learns the truth about her youth working as a housemaid and nanny for the Hirai family in a little house in Tokyo with a red gabled roof.
