Love , and no one knows it better than Seohyun, who's spent two years admiring a boy who barely knows that she exists. That boy being the incredibly smart, polite and unfairly hot Jung Yunho. Since freshman year, she's been watching from afar, but now that she's a junior she wants things to change. And nothing's standing in her way--except the fact that she knows nothing about boys.

17 years old and never been kissed, Seohyun can't tell a boy's head from his feet, and she needs help. Desperately. So when she unearths one of the secrets of Shim Changmin, the arrogant, stupid, and overed soccer captain of Westwood High, she blackmails him into helping her learn the ways of boys.

On a normal day, Seohyun would never talk to Changmin unless she had a baseball bat to smack his ungrateful with. But desperate times call for desperate measures. And who knows? Maybe Changmin isn't as stupid and insensitive as he seems to be... and maybe there's a chance that they might just be friends...
