All high school freshman Airi Hoshina ever wanted was to someday live in a cozy home with a loving husband, and find joy in the little things in life. As a result, she makes it her daily mission to get to school on time because school legend has it that the longer one's non-tardy streak is, the better boyfriend one will find. But just when her daily routine is working like clockwork, an occurrence of fairytale proportions threatens to disrupt her grand plan.

On the way to school one morning, Airi loses her mirror—one that had been passed down to her through generations—and suddenly finds herself in a bizarre situation. Never in her wildest dreams did she expect Aram, a little boy from a magical kingdom, to have emerged from the mirror in the short time it took her to track it down!
