Ryota, a virgin high school student, spent his days skipping class and hanging out in the nurse's office. The reason? He was deeply in love with the school nurse. On his way home, he would secretly pray in a secluded thicket: "God, please let me offer my virginity to her." He never imagined his wish would come true—until one fateful day, he witnessed his beloved teacher having an affair with the gym instructor. Overcome with despair, he cried out to God, only to have a heavenly, lustful version of the nurse appear before him in the form of an angelic temptress.
