The two are rivals who have competed for prizes since they can understand each other:
　　In kindergarten? Little Noppamas (child beauty pageant)
　　Elementary School? First percussionist (school orchestra)
　　High school? Cheerleader
　　University? Prom queen
　　Until in their most recent competition, the competition for the industry's best actress, an accident happens on the film set... And so, their souls are exchanged for each other's bodies!!!
　　Did destiny not understand that they HATE each other?
