From late 2004 to 2005, Kim played the heroine Choi Seo-hee in a television adaptation of Park Kyung-ni's celebrated novel "Toji" ("The Land"), which portrayed the lives and loves of peasants and the nobility ("yangban") in Korea at the turn of the 20th century, spanning from Japan's colonial rule to the division of the peninsula. The big-budget production was a hit, and Kim received a Best TV Actress nomination at the 2006 Baeksang Arts Awards.
