As it was mentioned below this movie should not be considered in romance genre, nor do I recommend it to strong Hyun Bin fans. In other words this movie is definetly not Hallyu style. The movie's story is about a man who has been hospitilized because of a mental illness and a nurse who is at the edge of a mental break down because of her sick father. I think, what happened between them can not be called love but more likely understanding each other / feeling each other, which was shown finely. The story is pretty plain-may be only a little above avarage-, and story telling follows by jumping between present and past. The simple story is supported by very good acting, by not only Hyun Bin but all the actors. Still naturally Hyun Bin takes the lead.I could not stop myself applausing his acting, since he did not impress me, but perfectly convinced me that he is mental. There is not much to say about the music since there wasn't too much music, except the end. It may be considered as a minus but I had the impression that it was knowingly done so, in order to support the feeling of the emptiness of life, as well as, the holes in caracters hearts. Since the movie is definetly suffocating and depressevie I believe the re-watch value is lower than I rated. Still I honestly liked the movie. As for shooting and acting it satisfied me a lot, and considering the story there was not a single moment when I did not think about the people around me or in the news who are fighting the same problems and end up exactly the same way that the caracters did. Overall I think it was a good movie but not for everyones taste.
