Ayaka was a sober girl wearing glasses and pigtails while being an honor student in the first grade. There is no boyfriend who is ignorant of sex. Ayaka, however, happened to try masturbation one day and awoke to sex. In search of pleasure, the swelling libido creates another face of Ayaka. Ayaka, who took off her glasses and changed her hairstyle, randomly etches as Ayaka who is free from libido.
