20-year-old Kanon Hayasaka, a holy, unfinished girl. With a pure heart like a pearl, a slender, white body, and disproportionately large I-cup breasts. Having lived her life according to her parents' wishes, the first path she chose of her own free will was to appear in an adult video. Though reserved, she harbors a hidden curiosity, and her shy yet uninhibited pursuit of pleasure is incredibly erotic. "Please teach me about sex..." This is the miraculous story of how a girl who has not yet been tainted by anything becomes an adult video actress.
