Yi Won is a descendant of the Joseon Dynasty and the head of the House of Yi. He worked as a general manager of Hyundai Home Shopping a Hyundai Department Store Group company until Prince Yi Gu died on July 16, 2005. He was born as the eldest son of Prince Gap of Korea, the 9th son of Prince Yi Kang by his wife at Hyehwa-dong, Jongno-gu, Seoul and became the adopted son of Prince Yi Gu, the twenty-ninth head of the Imperial house, though the legality of the adoption is contested. Those who dispute the legitimacy of the adoption point out that consent for the adoption of Prince Won was not given by other members of Imperial House, including Prince Yi Seok, the younger half-brother of Prince Gap, and Princess Yi Hae-won, the eldest surviving member of the house. Also, according to present Korean law, the traditional adoption after death of a foster parent to continue the line has been outlawed by legislation as of 2004. Another problem arises over whether Prince Won or his father Prince Gap is the senior member of the house. While the line of Prince Gang is the senior line following the death of Prince Gu, there are descendants of the elder sons of Prince Gang.
