Sumire, the most beautiful girl in the area, will participate in the annual hot spring trip to deepen the friendship of the neighborhood association again this year. However, his father, who accompanied him every time, was unable to go due to work, so this time he decided to accompany him alone as a caretaker. - She has known the uncles in the area since she was a child, and she has no vigilance for the innocent Sumire.
