I loved this movie so much, to say the least I shed more than a few tears multiples times. The romantic element in this story was truly amazing and the character development was beautiful. It really expresses the love between these two characters, even when the going goes tough.
*SPOLIER WARNING*
The scene where Xiao Bei had Chen Nian under him in that abandon building, I completely broke down. The whole scene was just terribly sad, I couldn't stop crying. The fact that he was willing to sacrifice his future for hers was so sad, that whole scene really showed how much the two characters loved each other.
