If you have seen so many negative reviews and contemplating whether to watch it or not just go ahead and watch it. It is one of the best drama ever made. It has parallel time line story just pay attention and watch it you wont regret it for sure. Kim eun sook never fails to amaze me! She made yet another masterpiece just like the glory and goblin, she for sure has something in her. I really wish to know how she comes up with all these stories!
