Masato, who doesn't have a job yet, works as a storekeeper at his family's convenience store. His mother's friend Ayane, who has returned to the countryside, will work as a part-time job under him who repeats the same days. Masato, who was attracted by her melancholy, mature charm, became conscious of her so much that he even dreamed of her. Ayane gently refuses because of her hesitation, but she is overwhelmed by his single-minded feelings, and she ends up overlapping her body with a one-time promise.
