(EDIT: I'm made a mistranslation. 'Life character', this phrase's meaning is closer to best character than memorable character, thus it can be expanded to the best character she has ever played in her life)
Daum Cafe: Try to argue, this is the best character of this actress
-Lee Bo Young --> Jang Hye Sung
-Lee Young Ae --> Dae Jang Geum
-Jeon Ji Hyun's most memorable in 'My Sassy Girl'
-I liked Gong Hyo Jin as Tae Gong Shil ㅠㅠ Taeyang
-Chae Jung Ahn as Han Yoo Joo in 'Coffee Prince' and Jung Ryeo Won as Yoo Hee Jin in 'My Name is Kim Sam Soon'. They weren't female leads but those are by far their most memorable characters
-Lee Da Hae as Joo Yoo Rin in 'My Girl'. Try to argue?!!
