I love the transition of character for both Mu Mu and Zhao Zhao, especially Mu Mu. In the first arc, Mu Mu was somewhat naive, cute and innocent and Zhao Zhao was her world. For Zhao Zhao, he was a bit cocky, somewhat arrogant and living life in the fast lane. In the current arc, Mu Mu has became a matured and confident career woman, who knows her worth, and Zhao Zhao became this conflicted, lost soul and living life with full of regrets. Both Esther and He Yu are excellent in portraying their characters through these changes. Well done to them both!
