This story has a lot of potential, but I do not know; the story was so boring for me because it did not make me focus while I watched. I keep falling asleep. And maybe because I kept falling asleep I was not able to focus or make a connection to any of the characters, which was a letdown because I was looking forward to this story since this is the only series that offers this kind of time travel. Also, I was not convince with the reasoning of the villain (if you can call him that) especially the one in the Joseon time. However, I will not tell anyone to not watch this because maybe it will be your cup of tea and will enjoy.
