Taichi Yaegashi, Iori Nagase, Himeko Inaba, Yoshifumi Aoki and Yui Kiriyama are all members of the Cultural Research Club. One day, Yoshifumi and Yui claim to have temporarily switched bodies the previous night. Although everyone is pretty sceptical of this, it is soon proven to be real when Taichi suddenly switches bodies with Iori and gets hit on by the class president, Maiko Fujishima. After spending the rest of the afternoon convincing Himeko what had happened is real, they eventually switch back to their original bodies.
