 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 . She is constantly sighing , being made to go along with Kōhei 's meaningless jokes . 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 <unk> toward those around her , but she shows her true character just to Kōhei , who leaves a terrible first impression . Kōhei gets to know a quiet classmate named Akane Satomura who does not readily open her heart up to those around her , and refuses any help Kōhei may offer .
