Yuuichi, a poor college student, spends his days studying for a scholarship and working part-time. One day, the world-famous supermodel Reo Ichinose visits the café where he works. As the store goes crazy at the unexpected celebrity appearance, Reo tells the clueless Yuuichi: "I've come to pick you up," and proposes to him...!? Much to Yuuichi's confusion, he finds himself swept up in a fairytale-esque love story that started from a promise he'd long since forgotten.
