A single email arrived. It contained only one sentence: "I want to lose my virginity." Captivated by those words, the crew decided to meet the woman in person. Her name is Yamazaki Naomi, a 20-year-old part-time worker who dropped out of junior college. She has never dated a man before—a pure-hearted girl. As she enters her 20th year, she desires her first sexual experience. One week later, the crew arrives at her home. Shyly lowering her head, she begins undressing. As she is gently loved, her body relaxes, and she eventually completes her first experience. The timid girl gradually transforms into a woman, displaying a remarkable transformation.
