Kanon, 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. He has known Mr./Ms. uncles in the area since he was a child, and he has no vigilance in his innocence. However, ugly fathers who were lustful for the grown appearance of a beautiful girl they had known for a long time took advantage of Kanon's purity and gradually began to repeat sexual harassment.
