Han Jae Hee, in The Innocent Man, She is vulnerable, but if you see behind his vulnerable side, there is a strong will to survive to get out from supposed the pit of a bottom place she want to escape, she always find a way how to escape, an opportunistic antagonist.
Ji An in My Mister, She is the female lead I want to see more often in kdramaland. A grey female lead character is always a welcome, particularly if they are written with this kind of depth. She is strong, always find a way to survive in any kind of difficult situation. Find A warm place where she gets accepted by people is a treasure feeling for her.
