“If You are the One”: love lost vs love unachievable
Personally this movie has eveything I expected from a good movie: director( Xiaogang Feng), actor(Yo Ge), actress(Qi Shu), story and one more, the beautiful scene both in China and Japan. 

I will not be a fun killer here. You have to watch it yourself. 

BTW, there is lots of humor in the moive, I am not sure you can fully get it or not. If you want, you are more than welcome to discuss with me about it.
