Love*Com Vol. 1 by Aya Nakahara

Main Characters: High-schoolers Risa Koisumi and Atsushi Ôtani
Location: Japan
Time period: Contemporary
Genre: YA Manga, Romantic comedy

Risa Koisumi is the tallest girl in her class; Atsushi Ôtani is the shortest boy. They can't stand each other, especially since everyone at school compares them to a comedy team--think "Mutt and Jeff." Then they wind up having to go to summer school. There's a new boy --Suzuki--in their class. Risa is instantly attracted--after all, Suzuki is as tall as she is. Ôtani offers to help her get together with Suzuki if she'll help him get together with her friend, Chiharu Tanaka. What follows, as you might guess, is classic farce. Suzuki and Chiharu wind up crushing on each other and everyone thinks that Risa and Ôtani really like each other because of the way they've been talking each other up to the others.

This is a very funny, very silly story. I mean, you know from the beginning that Risa and Ôtani will wind up together, but the fun will be in seeing how long they can fight against it without getting annoying.
