Her next two roles saw her playing a single mother with culinary dreams in the television series "Only You" (2005) and a jilted girl looking for employment in "Exhibition of Fireworks" (2006). Both series underperformed and she reverted to a glamorous character for the couple-swapping film "Love Now" (2007). In 2006, she signed an exclusive contract with BH Entertainment owned by Lee Byung-hun, and became one of the 1st talents of the newly found agency; BH Entertainment also manages many actors including Go Soo, Jin Goo, and Han Hyo-joo.
