Donghae always knew that he had a lot of disadvantages when it came to finding relationship partners. First was his glasses which, although gives him a dependable sort of look, gets him classified as a nerd. Second was his inexperience with, not only relationships, but almost everything in life. He was book smart but definitely not street smart. He could give you a list of all these disadvantages but it is, apparently, outdated. Never in his wildest dreams would Donghae have guessed his gender to be one of these disadvantages.

And please note, Lee Donghae is after a girl.

Lee Donghae, being his school's, Saint Peter's School for Boys, 11th grade representative, is to spend three months as an exchange student at their sister school, Saint Lilian's School for Girls, along with the rest of the student council. Many are envious of this opportunity but Donghae only sees it as an opportunity to humiliate himself. His best friend, Lee Hyukjae, tells him to cheer up and look at this as an opportunity to get a girlfriend, reasoning that the girls probably wouldn't be as picky as usual considering the fact that they will be the only members of the opposite in the area.

It isn't very long into their stay that Donghae decides that he has a crush on someone. Saint Lilian's student council president, Moon Haneul, to be exact. The only problem is: Haneul is a lesbian and in a relationship with the meanest girl in Saint Lilian's. Now Donghae, being a guy, doesn't want to fight with a girl and decides to back out of the game, thinking that there was no "game" anyway, what with Haneul and her girlfriend staying strong.

And then, the games begin.
