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 got a job at a restaurant so she could be close to Ôtani's cram school. But now it looks like one of her coworkers wants to get close to her! Kohori is cute and short and majorly into Umibôzu, but Risa just wants to be friends. When circumstances conspire to make it look like she's interested in more, what will a super-stressed Ôtani do?
