At the end of summer, high school girl Harley unexpectedly became a desk mate with her childhood acquaintance, the campus heartthrob Flynn. After learning about her boyfriend Danny's infidelity, Harley angrily stormed into the baseball field to question him, but was mistakenly hit on the head by hitter Flynn and suffered from amnesia. Flynn took on the responsibility of taking care of Harley out of guilt, and the two gradually developed feelings for each other through misunderstandings and entanglements.
