Kōhei Inuzuka is an assistant teacher who has been raising his daughter, Tsumugi, by himself following the death of his wife, Tae, six months ago, often feeding her pre-made bento lunches. They meet Kōhei's student Kotori, who invites them to her family's restaurant. That night, Kōhei sees Tsumugi craving a proper meal like her mother used to make, and rushes her to the restaurant. Despite it being closed, Kotori asks them to stay and makes them pot rice. Kōhei promises to cook Tsumugi proper meals from now on. Kotori catches him off-guard when she asks him to cook and have dinner with her.
