Allen Ren has been one of my favorite actor and I started to watch this drama and found out that Fair Xing is the actress that plays the lead character. I knew this was going to be good. I just had finish "my little Happiness" which I loved. This drama has everything you want. A cute and funny start between the main characters. A great romantic love story for both the main leads and the second leads which I love also. The story has a mystery, they met years before, good friendship, and loyalty among the couples. There is a scientific story with the lead male character and the great support of the lead female character and the second lead characters. The story is well written and the way the story progresses from beginning to end. Since I started this drama every episode makes me consume and I can't wait to the next episode. I hate that is over and would like the story to continue. A must watch. love it.
