"Sexiness is a fundamental truth...!!"

One day, the uptight morals committee rep Asagiri stumbles upon his classmate Yumegahara in the school library—drawing erotic manga. Turns out Yumegahara, who's shy around men, is using her own steamy comics (with herself as the heroine!) to train herself to be more comfortable. Determined to reform her scandalous ways, Asagiri volunteers to be her practice model. But Yumegahara's imagination knows no bounds... and before he knows it, she's the one turning the tables, "You'll take responsibility... won't you?"
