Time traveling to solve murder mystery is the one sentence story of this drama, liked the crowned prince. Park yun chun and ha ji min did their parts well. The crown prince while searching for the murderers of his crown princess ends up in bak ha's rooftop, 300 years later. An interesting love story line which keeps you on your toes, liked this drama. Even though at some point story is predictable, it is not dragging at all. Overall a good drama worth watching. Must say what an ending! aah!
