Really like the movie. Gong yoo is good as always. Forbidden love is interesting thing at the beginning but it get complicated as time passes and you got webbed in it before realizing and at the end you ended up sacrificing your feeling for whatever the reason behind it, same goes for the movie. They sacrificed their love for their child. Kind a feel bad for them . But overall good emotions was showned , pain you feel when you got parted with your lover.
