Megumi Fujimiya, who is attracting attention as an onapet idol from school men.
She is a childhood friend and a pure school girl in the middle of youth who has just become a lover with baseball club ace Takashi Katayama.
There appears a life guidance teacher who has a mysterious Seikatsu guidance notebook that can change the perception of the other party.
“Fujimiya … Did you forget that students who have a lover must take” sexual activity guidance “as a compulsory subject?” “I’m sorry … I forgot
such an important thing !!”
Megumi, whose cognition has been altered, will be
repaired in the health room by “sexual activity guidance” in which gene juice is poured into the uterus without a contraceptive, which is not possible as Fuka says.
