The story is really sad and it's terrifying to know that these situations happened in real life, not only once or twice. The cast is another thing; you can clearly see who's a senior to who. I think I can point it out that the best actor or actress in this movie is Yoo Sun. It's incredible how much emotion she brings to her character. As for the main person who lead me to this movie, Dongho, I'm also satisfied. A bit of practice and he's going to turn out an incredible actor, I'm telling you. The music gave me chills several times during the film, especially the intense piano sounds and such.
