The story is different and it hypnotizes you, episode by episode. A short drama but well written. It is a person that comes from the past and helps the love of his life in the future. I really like the romance between the lead characters. It is develop slowly and simple. Especially as the traveler remembers his past and find his love has been reincarnated with the same name and looks. I love how the writer makes the lead male character learn about everything in the future. How he sings is wonderful. The decision they have to make to survive in this world and that sometime people don't change. The performances by the actors is great. It is short drama but it is a very well thought out and explain. You can follow the story clear and simple. The ending was not my favorite . It left us hanging for a second season that will never be made.
