Hikari Hanazono, the main character, has always been second to Kei Takishima. While Hikari considers Kei a rival and somewhat of a friend, Kei loves Hikari. Everyone knows this, but she is too dense to notice. Their wrestling loving fathers first introduced them to one another when they were 6 years old.
Assuming that she was the best in wrestling, young Hikari challenged Kei to a wrestling match only to be thoroughly defeated by him. Ever since that fateful incident, Hikari swore to beat Kei in school grades, a sporting event - anything. To do this she has enrolled in the same school as Kei since elementary.
