I started watching this drama cause the summary sounded very interesting, mixing mystery, fantasy anda thirller, genres I specially like.

The first four episodes were very good and kept me hooked, though soon after the plot loses strength and gets boring. The world travelling itself is not the main topic till the very last ep, which disappointed me a little. In fact at the end there's a final plot twist I would have enjoyed way before in the show.

Of course the story of the main couple is interesting as well as the crime investigation.

Acting not bad but OST not remarkable.

In summary, not a bad show but I expected more.
