Yoshie Fujisawa is a woman who single-handedly raised her son, Hirokazu. Working at a local company, she had successfully sent her son to college, and they were now in their third year of this new chapter. One day, the family went on a trip together. Wanting to avoid burdening his mother, Hirokazu enthusiastically took charge of all the travel preparations himself. But upon arriving at the inn and seeing his mother's figure, he was overcome by a strange, unfamiliar emotion he had never felt before. That night, the bond between mother and son deepened in ways beyond imagination, crossing a new boundary together.
