Sun Woo Hwan (Lee Seung Ki), who was also studying in New York, was ordered to return to Korea by his grandmother, Jang Sook Ja, to learn how to manage her food company. Eun Sung and Hwan, who were on the same flight back home, accidentally had their luggage bags exchanged, which led to several misunderstandings between the two of them.

The police, upon finding Go's belongings on the thief, mistakenly identified the thief as Go and a death certificate for Go was promptly issued. Go decided to lie low and not tell his family that he was alive so that his family could claim his life insurance money and use it to clear the debts. However his second wife, Baek Sung Hee, kicked her stepchildren, Eun Sung and Eun Woo, out of the house after collecting the insurance money and moved into a new home with her daughter, Yoo Seung Mi (Moon Chae Won).
