Ryoko lives with her husband's child, Yoshio. Gradually, I became aware of Yoshio, who was growing into an adult, as the opposite sex. I can't stop thinking about Yoshio, even though I think it's a bad thing. And Yoshio was also secretly delusional about the plump and ripe Ryoko! Ryoko and Yoshio find out about it, and their feelings become intertwined and they passionately seek each other.
