After appearing as a model in a well-known fashion magazine, Nanaki Fujishiro becomes convinced she is the most beautiful girl in existence. She looks down on those who neglect their appearance—particularly her shy classmate Kanade Kurokawa—and navigates school life valuing looks above everything else, surrounding herself with popular, attractive friends and a suitably handsome boyfriend. Believing her beauty guarantees success, Nanaki is blindsided when one of her friends reveals her boyfriend is cheating. When she confronts him, she gets dumped, insulted, and left sobbing—until Kanade tumbles out of a nearby storage locker where she was hiding after overhearing the entire scene.
Kanade, who only wanted to live a quiet, uneventful school life, is just as shocked as Nanaki. Despite Nanaki's past treatment of her, Kanade feels empathy for the popular girl's heartbreak and instinctively moves to comfort her. Against all odds, Nanaki and Kanade grow closer to each other and gradually drift away from everyone else. As Nanaki introduces Kanade to the world of fashion and comes to appreciate Kanade's otaku hobbies, feelings neither of them expected begin to surface.
