Young-sae was once acclaimed as the most-promising dancer. Losing his partner and lover, he lost his enthusiasm in sports dancing for two years.

Now, he decides to make a comeback at the Championships held in Seoul three months later. His new partner is a girl named Chae-min who lives in China and won in a dance contest. It is then discovered that Chae-ryn has come in place of her sister and she knows nothing about dancing!

Young-sae wants to send her back at first. When he sees Chae-ryn's determination to become a dancer, he starts to train her with the hardest lessons.

Step by step, their dancing starts to sparkle, so as their relationship.
