A delusional geek girl who has only had sex with one person has decided to appear. She is a plain girl with glasses who masturbates to erotic manga and erotic anime, but when she takes off her clothes, she turns out to be a busty nymphomaniac. It's true that the quieter a girl is, the more erotic she is, and when she fantasizes, the reaction when she explodes is a little too erotic. Once she gets used to it, she is a very nice girl who laughs a lot.
