Lee Seunghyun was living his peaceful life with his precious daughter in New York City and did not imagine that he was going to face his bitter past when he got the promotion letter along with his transfer letter to none other than Seoul city in South Korea; the city where he had learned true meaning of life. Even though it was bitter fact, he had learnt enough to change himself to something that he was not six year back.

He was an investment banker in a renounced bank and was one of the high officials beside his young age. Their Seoul branch was not functioning well from last few months and the board decided to send their only Korean employee who was not only witty but also has lots of intelligent tricks to develop whatever it was lacking. In nut shell he was one package banker that every company wants.

What will happen when he goes back to his country? How will he react when he face his own past making effort to get him?
