Everything is first-time, 19-year-old Peko Fujitani, virgin debut. She is still innocent, but she transforms into an adult woman through "sex". Seeing other people's H, showing naked bodies, masturbating in public, giving blowjobs, and having SEX are all new experiences, so expectations and anxiety are mixed. There are lots of reactions because it's a documentary, such as tears during shooting and the sudden start of menstruation.
