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.

Someone didn't make it into college, and it wasn't Ôtani! Suzuki, thrown by his family's harsh expectations, failed the college entrance exam. And now some bruiser who did get accepted wants Chiharu for himself! Ôtani jumps to the rescue by claiming Suzuki is a judo expert who will fight for Chiharu's hand! But is one week really enough time to turn Suzuki into a black belt?
