When you first met someone, what were your thoughts on them? If they did something wrong, would it convince you that they're bad? Kim Sun Hye meet "someone" on her first day in her new school. He accidently did something and that convinced her that he was nothing but a playboy. She hated him since the first day she saw him, those puppy eyes, to everyone they may be cute, but to her, it was nothing but annoying. 

Sun Hye always tries to keep her distance away from the boy but there were many events that brought them away from each other but he always seems to get the chance to be able to get her attention. Soon, there were bad news on both side's family, and they needed each other to achieve their goal.

Would they work together or avoid each other even when it's a bad time to argue?
