High school. The last four years of a teenager's, emotional, overly-dramatic life. Set out to be for the education of the young people, yet, it is also the times of finding out one's true self, searching for real friends and fitting in.

After being cheated on, or dumped for different girls five times by all of her ex's, Hwang Ma Ri has had enough. No more boyfriends for her, absolutely not. She can't trust yet another man. Though, she's turned hiprocritical, crushing on the new guy in school, Kim Himchan. Does that mean she'll ever trust this one? But, it's so tempting... he's the perfect, down-to-earth guy, and on the plus side, he's way above average in the 'looks' category. They've also already hit it off as great friends.

But, her best friend has sort of helped her with that situation. She's told her that Himchan is her ex; that Himchan only transfered to the school for her.

Ma Ri can now finally get over the guy, knowing she'll never do anything that could cause even the tiniest scratches in her relationship with her best friend. Right? Right??
