Risa Koizumi is the tallest girl in class, and the last thing she wants is the humiliation of standing next to Atsushi Ôtani, the shortest guy. Fate and the whole school have other ideas, and the two find themselves cast as the unwilling stars of a bizarre romantic comedy duo.

Risa's life should be perfect. After all, she's finally dating the guy she loves. But Ôtani's never actually said that he loves her, and they don't even act like boyfriend and girlfriend. Wasn't dating supposed to fix all that? To make matters worse, graduation is looming and Risa's not sure she likes the way her future with Ôtani looks. Could this be the end of her love and their friendship?
