Kitamori Yuki was particular about her promise to her mother-in-law Hana. The promise is that, as the daughter-in-law of Koichi, the eldest son of the Kitamori family, Hana entrusts everything to Yuki, but wants her entire family to come see her on her birthday. At that time, her second son Keisuke's daughter Megumi, who is her private taxi driver, made a mistake, and she was overwhelmed and approached Yuki for advice. Eventually, her mother Kayo of Megumi learned about this, but a period was quietly struck by her women coming to a conclusion that should be the food for Megumi's growth.
