I really enjoyed this movie. I appreciate when actors can convey emotions through their eyes, and Jooyoung and Fan Bingbing did this well. Their chemistry was almost perfect. Although I watched without subtitles, I can understand Korean well enough to follow along. However, I was disappointed that there were no subtitles for the sign language parts. This made it difficult for me to understand those scenes, especially the ending. Even if you can't understand this movie due to language barriers it's a good movie. Honestly, I struggle with liking movies, because I feel they are always lacking something but I liked this movie, it didn't lack anything, I feel like I could see a natural connection forming between the two main characters, and it didn't feel forced at all, it felt very natural. I would say I think this movie was very well done and it would be worth watching at least once.
