Kōhei Orihara is a young man in high school living a normal life. He tends to tease the girls he knows, especially his childhood friend Mizuka Nagamori, but deep down he is generally nice to girls. Mizuka usually takes good care of him, and worries about Kōhei, wondering if he could suddenly get a girlfriend. Kōhei meets a transfer student named Rumi Nanase early in the story whose goal is to become a "true maiden" and to that end, she behaves maidenly toward those around her, but she shows her true character just to Kōhei who leaves a terrible first impression. Kōhei gets to know a generally quite classmate named Akane Satomura who does not really open her heart up to those around her, and any time Kōhei tries to do something for her, she replies, "no".
