This is the move version of Gu Man's book "Silent Separation".

Well acted, and well-depicted. The flashbacks to the original misunderstandings were clear and concise. The current-time situation was presented well, and ML did an outstanding job of portraying his frustration / desperation. I liked the love-rival side characters too -- both were realistic, and also stepped back when they realized they had no chance.

The movie is true to the original story (likely because Gu Man was also the screenwriter for the movie), and the movie is MUCH better than the 32-episode drama "My Sunshine" (2015). The drama was tedious, especially the over-long flashbacks, and changed important details.
