Found this website very recently. I am a Singaporean Chinese. I agree that CJW is wonderful in her expressions. She is very competent in conveying emotions and feelings. I have seen her in three other Korean TV dramas but I think WLS must be the most demanding as she has to portray what went through Youjin's psyche and thought process. If it is a play, she could utter her thoughts aloud in soliloquy. The same goes for her male lead BYJ, I guess. Both put up a very competent act. Look forward to more of their shows.
