I remember seeing this back in 2011. At first, one may think the storyline is quite common, and one may find the film boring. But deeper plots and backstories are unraveled as the story progresses which leads to a puzzling and chilling/eerie ending. Lee Yo Won, playing the central character did a wonderful job, complimented by Lee Dong Wook and of course, the amazing Ryu Sung Ryong . A well-written story that has bits of romance, drama, fantasy, and mystery. A fantastic film that can fit into multiple genres.
