Risa Koizumi and Atsushi Otani are the most popular comedy duo in high school: she's 5'10", well above the average Japanese girl, while he's a 5'5" tall basketball player who refuses to let anyone walk all over him. They bicker constantly, insult each other in Osaka dialect, and burst out laughing over the same stupid things, so much so that everyone considers them the perfect comedy duo. The real problem arises when Risa begins to develop real feelings for the annoying dwarf, clashing with her own height issues and the incredible emotional blindness of Otani, who sees her only as a "guy friend." Between failed declarations of love, burning disappointments, unexpected jealousies, and a friendship so deep it hurts, this story unfolds a captivating and merciless romantic comedy about overcoming one's insecurities and the struggle to make one's heart know who to fall for.
