I watched this movie for a class today. It made me cry so much. A truly heart-touching story. At the end of the movie, it made me think: would I be able to make the same sacrifice Kang Jae Hyuk had if I were the only one who could? The storyline, directing, cinematography, and acting were just perfect. This is an extraordinary movie, and I hope you will watch it as it is one of the best movies I have ever watched.
