Introducing Chung Yul and Sa Rang, twin sisters that couldn"t be more different form each other! One is very feminine and quiet, while the other is loud, wild and tomboyish. When these girls transfer to a new school, they meet two boys that will change the way they think about life and love. One is a shy and polite student, and the other is a star soccer player whose father is a polar bear (seriously)! When these four teenagers get together, you can bet that it won"t be just an ordinary day at school!
