This is a sad but good movie.

I have watched the series version with Zheng Shuang and Ma Tian Yu and I really enjoyed watching the story as well.
Both the movie and series deal with a difficult and more mature issue, such as bullying, divorce and suicide (Not your typical c-drama romance topic). The actors and actresses I thought portrayed their roles well, especially the movie version. It's like you can feel her heartache and sorrow just by looking at her eyes.

This movie (and the series) are not for everyone, but if you like a "darker" drama theme, I would definitely recommend watching the movie and the series.
