Two young beautiful friends Jin Sung and So Hee have forged a 'close' relationship but this is challenged when the ballet school holds its annual competition to see who will go forward to the national competition and win a scholarship to a Russian ballet school. The better of the 2 friends So Hee looks all set to win, when it becomes apparent that Jin Sung is becoming more and more jealous. She then bumps into Hae Ju, a former fat girl who stuffed her face all day and appeared quite mad, who reveals that she is now thin because of the wishing stairs and the synonymous appearance of the 29th step. Jin Sung then decides to give the stairs a go herself.
