While attending university, aspiring novelist Riku Kanbayashi met Minami Maezono, an aspiring musician. The two fell in love at first sight and got married. Eight years later, Riku had become a bestselling author, while Minami had given up on her dreams. One morning, after fighting with Minami, Riku woke up to find himself in a world where Minami was a huge star, and he was just an editor—not a novelist. Moreover, the two had never met. Confused, Riku scrambled to restore his original world. He managed to get close to Minami, but beside her stood the man she loved.
