Naoto Hachioji is a shy second year student who avoids others and spends most of his time alone in the art room. One day first year girl Hayase Nagatoro encounters him, and on seeing the manga he drew, starts to tease him. Soon she and her friends are heading to the art room to tease him some more. Sensing his awkwardness they flirt with him... while neither can admit it they start to develop feelings for each other... that doesn't mean she will stop teasing him.
On the face of it a comedy about somebody being bullied doesn't sound too appealing; however this manages to pull it off as it becomes clear to the viewer fairly early on that our two protagonists have unstated feelings for each other. Every episode has plenty of laughs and Nagatoro and her friends do occasionally, and hilariously, fall victim to their own schemes. All of the characters are entertaining in their own way and none are as cruel as they first appear. The animation and character designs are good. Overall I'd certainly recommend this series... I just wish there were more episodes.
