Sumire, the most beautiful girl in the area, will participate in the annual hot spring trip to strengthen the friendship of the neighborhood association. However, my dad, who always goes with me, couldn't go because of work, so this time I decided to go with him alone as a caregiver. The doctors in the area had known her since childhood. Sumire was innocent and had no caution or anything. However, ugly old men, lusting after the mature appearance of a beautiful girl they had known for a long time, took advantage of Sumire's naivety and gradually began to sexually harass her repeatedly.
