Iwase Ken and Yoshida Rei have been by each other's sides since elementary school, and it always seemed to be a given that they would end up together. Why then, Ken wonders to himself on Rei's wedding day, is he not the one sitting beside her? Looking back at his life with Rei and their friends, Mikio, Eri, and Tsuru through a wedding slideshow, Ken is filled with regret as he realizes how many mistakes he made -- and how many chances he missed to tell Rei his feelings. Wishing for nothing more than to go back and change it all, Ken is unprepared when a rather unconventional fairy appears and offers him the chance to do exactly that. Now given the opportunity to change his and Rei's fate, Ken must not only increase his presence in her heart, but deter her from falling for her future groom.
