Top students Yukino and Soichiro are finally beginning to realize they make better friends than rivals when Hideaki, the school's token pretty boy, decides for some reason to disturb their budding relationship.
Yukino, accustomed to being the number one student at her school, decides to take action when she is knocked off her perch by new boy Soichiro-Arima, but she did not count on falling in love with him.
Tsubasa, an old friend of Soichiro's from junior high, transfers to Soichiro's high school, where she vows to take Soichiro from Yukino, no matter what it takes.
