Kae Serinuma is what you might call "fujoshi". When she sees two boys talking, she starts to rave in crazy thoughts! One day, the favorite character of her anime dies, and the shock is enough to lose weight. With this, four school boys decide to call her out, but she does not seem to care - she'd find much better to see them all making out!

After having lost weight, Kae does extremely well in PE class. Seeing that, some girls from the soccer club ask Kae to help play in a practice match. Kae has full confidence in her soccer knowledge, but she actually only knows soccer from soccer anime and has never actually played herself. And so, Igarashi from the soccer club, as well as Nanashima, Shinomiya and Mutsumi try to help her out.

For the school cultural festival, Kae's class decides to host a cosplay café. Kae is fired up about designing the costumes not only for her classmates Igarashi and Nanashima, but also for Shinomiya, who's playing the role of a princess for his class which is putting on a play. But as excited as she gets about the costumes, she also has to help the history club set up its exhibition. With everyone's help, she manages to finish everything in time for the festival. And what follows is a date with the four hot guys...
