Food poisoning occurs at the small restaurant where Yukina works, and the business is suspended. Although they managed to resume business, the reputational damage was more than expected, and the number of customers dropped sharply. Most of the employees have left, leaving only the hall manager Yukina and the cook Kawakami. One day, Yukina is entrusted with the training of newly hired hall staff. However, the newcomer turns out to be a middle-aged man who is older than Yukina's father and has been laid off.
