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.
