At Sakuragahori High School, second-year student Haruma Kiki has been continuing her role as the "Leader" (male role) in the social dance club, despite wanting to dance as a "Partner" (female role) due to her tall stature. One day, Kiki is informed by her childhood friend that they will no longer be a pair, prompting her to search for a new partner. However, she struggles to find a new pair and often dances alone after school, dreaming of the partner she longs for. It is then that the petite and delicate first-year student, Torabimi Michiru, approaches her and says, "Please be my partner," taking her hand.
