The food poisoning occurred at a small restaurant where Yukina worked and she was suspended. Although we have tried to restore business activities, the damage caused by rumors is more than expected and the number of customers drops sharply. Most of the employees left, and everything left was Yukinina, the person in charge of the lobby and Kawakami, who was in charge of the chef. One day, she was tasked with training new hall staff. However, the newcomer is a middle -aged man restructuring, older than Yukina's father.
