Brilliant Legacy

Go Eun-sung (Han Hyo-joo) was studying overseas in New York and returned to Korea during her vacation to bring her autistic brother, Eun-woo (Yeon Joon-seok), to the United States to study music. Sunwoo Hwan (Lee Seung-gi), who was also studying in New York, was ordered to return to Korea by his grandmother, Jang Sook-ja (Ban Hyo-jung), 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. Go Pyung-joong (Jeon In-taek), Eun-sung's father, was struggling to save his company from going bankrupt. One day, his wallet and valuables were stolen by a thief who subsequently died in a gas explosion accident. The police, upon finding Pyung-joong's belongings on the thief, mistakenly identified the thief as him and a death certificate for Pyung-joong was promptly issued. He 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 (Kim Mi-sook), 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). Seung-mi was also Hwan's longtime best friend, hoping to be something more. [About] Brilliant Legacy is a 2009 South Korean television series starring Han Hyo-joo, Lee Seung-gi, Bae Soo-bin and Moon Chae-won.
