Hanadera Keisuke is obsessed with yuri, and he's read all the Yuri Hime manga. However, he is sadly aware that there is one thing a lesbian romance absolutely does not need-- him. One day, a student named Akane transferred to his class from an all-girls school. She used to go to school with another classmate, Saori, and Akane immediately tried to pick up their friendship. However, her clinginess, desire for alone-time, and intensity all convinced Keisuke that he was finally seeing yuri in reality!

Is there truth to his observations, or is he viewing the world through yuri-tinted glasses?
