As flower petals drift and a gentle breeze rustles through the trees, love seems to intoxicate the minds of high schoolers everywhere. However, Ren Yaotome is not one of them. Despite her mature demeanor and feminine attire, she lacks the experience in romance that most of her peers have. Though she yearns for a fairytale love, no one has caught her eye - certainly not the blunt and strict Yuusei Hidaka, with whom she clashes on a regular basis. Nevertheless, even he has a soft spot for his little sister, Manami.
It appears that Yaotome and Hidaka are destined to never see eye to eye - until a close encounter with a car accident causes Yaotome and Manami to switch bodies! The two work together to keep their predicament hidden, and when an opportunity to switch back presents itself, Yaotome eagerly accepts - but why is Manami so hesitant?
