I definitely have to watch this a second time and will update my review after my second watch.

This drama has an interesting storyline. It's a time travel themed drama. However, this is not like the usual time travel drama where the characters meet the version of them in the past or the future. In this drama, the characters travel to a different time but meeting other characters who look exactly like them, but not them. Somehow these four (or six if you count the villain) characters from two different timelines are connected. I don't know if it's my concentration or something else, but this confuses me. I lost track of who is who and why. That's why I said that I have to re-watch this drama with more focus.

Overall, this is a beautiful story and refreshing because it's different.
