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 and Ôtani are totally dating! But it's totally weird. Risa is so used to treating Ôtani like a friend that she has no idea how to act like a girlfriend. Luckily, Ôtani knows just where to go to save a failing date. Could this be happily ever after? Not if Risa's new rival has anything to say about it!
