Song Ji Hyo's performance is outstanding! Her best ever role in my opinion. I think its much better than Mystic Pop-up bar. Scarier more mysterious scenes. The cast is great, the story moves along quickly and the plot twist in the end threw me off. I love the scenes and Ji Hyo's oufits. The lighting and colors in this dramas definitely pulls everything together. I like how the stories are depicted. There isn't much romance in this drama but there's a lot of mystery. I thought I knew what was going to happen but it took a different turn. Very unexpected in a good way.
