Moon Jongup is a quiet person.

He likes his surrounding to be peaceful and fresh.

He likes to be alone, dancing.

He likes to mind his own business.

But one day, his teacher had asked him to pair up with a girl to do a task. Apparently this girl is not just an ordinary peron but a talkative, weird and annoying-kind of girl. Totally opposite of the Moon Jongup. He could ignore her this whole proccess of the task thing but something made him c u r i o u s.

Curious of the outside world with other people, curious of other people's passion. And mostly, curious how this girl named Kim  Yoona can actually made him do things that he wouldn't even think he could do.

Those things, well, you can say it's something different for Jongup. As for Kim Yoona, she was one naive girl.
