It is a Japanese remake of the American film Ghost. They both used the song Unchained Melody, have the same story as one of the lovers will die and became a ghost, but the plot in the Japanese version is different. It is ver romantic, emotional and you can feel the grief after the lost of someone you love. The special effects is good, the fighting scene and the thrill when uncovering the reason of death. The wedding ceremony is so surreal but romantic indeed. Well, I feel both happy and sad at the end. It is fantasy but it gives hopes and idea of eternal love. Both actors were good and I like Song Seun Hun (male lead) speaking Nihonggo. Overall, I like the movie.
