Could something that occurred 15 years ago connect two distinct people that have not met before? Kim Soo Mi (Hye Jeong) is an international known business woman. She works as the owner of Disney Land in Orlando, Florida. When her mother dies, she is forced to go back to South Korea and inherit her Mothers Business as a CEO for a circus. She is constantly afraid which has made her develop a nervous disorder known as Anxiety. This sometimes interferes with her daily life and has to see a private doctor. She doesnt know the reason for her Anxiety but doctors believe it has to do something with her past. So in order to get rid of this, she needs to remember her past even if she is afraid. On the other hand, Lee Dong Hee (Kim Myung Soo) is a man that has no worries and enjoys life. He lives in the states with his mom and dad who love him and always are there for him. He has a part time job as a doctor in "Jackson Memorial Hospital." One day he is offered a high paying salary if he moves to Seoul, South Korea for 5 months. Once he settles down in Korea he meets Kim Soo Mi. Could fate reunite them in order for them to learn about the past? Or will fate separate them so they could move on?
