Jung Soo Jung is the usual bubbly type of girl that you know.She has the confidence,thick skin and great defiance,but she can also be a big coward when it comes to facing the person whom she is scared of.She's a good dancer and shows it off like how she should be. Kim Jong In on the other hand is cold-hearted boy who doesn't let his feelings out.He's got the talent,the braveness to show off his talent and arrogance to think that no one could topple his talent in dancing. Oh Sehun the 'narcisstic gay' as Soo Jung would call him,likes to look at himself at his hand-held mirror that he carries around everywhere he goes,just to check if his bangs are on their right places,his lips are colored light pink like how they should and also to check if he has something on his nose. Jung Soo Yeon is Soo Jung's mean and foul-mouthed sister.She glares at everyone she looks at and unintentionally curses at them but she's still loved and idolized by the boys in her high school by her beauty. Being at the same dance class but hardly knowing each other. Both having great talents in dancing,but different in personalities. Will they collaborate to achieve a certain goal?
