While the first few episodes were interesting, the story quickly loses steam and begins to fall apart. It seems like the writers had no idea how to expand upon the original concept and were just throwing in random dangers and half baked villains. By the end of the drama the plot became almost non sensical.
However, the performances and relationship between the leads is the saving grace of the show. Han Hyojoo does a great job of playing a clueless woman who is out of her depth after being sucked into another world. The romance was engaging throughout and the chemistry makes the show enjoyable to watch. Even though I was not invested in the mystery of the show I was eager to watch the next episode just to see how the romance played out.
