Yüto Ayase is a second-year student at Private High School, Hakujö Academy. One day he goes to the library to return a magazine for his bishönen friend, Nobunaga Asakura. There, he bumps into the most popular girl in school, Haruka Nogizaka, and discovers her secret: that she is an otaku, which greatly distresses her. Haruka starts avoiding Yüto which causes his schoolmates to suspect that Yüto 'did something to her'. Eventually, Yüto finds Haruka on the school roof where he vows he will not tell anyone about her interest if she does not want anyone else to know. Haruka is relieved and happy that Yüto is so understanding.
