20-year-old sacred unfinished girl, Kanon Hayasaka. Possessing a pure heart like a pearl and a pale, slender body, her disproportionately large I-cup breasts stand out. Having lived according to her parents' words until now, the first path she chose for herself was appearing in adult videos. Though shy by nature, she harbors a hidden curiosity, and her embarrassed yet earnest pursuit of pleasure is erotic and captivating. This is a miraculous story depicting her transformation from a pure, untouched girl into an AV actress, before she's been colored by the world. We want you to answer her plea, "Please teach me about sex..." and experience her growth alongside her.
