Beginning was good, however as the episodes went on the story did not make sense, it is clear how the writers did not think the storyline through. They also dragged the show too much, the story was going in a loop and there were many episodes where nothing was happening. Most importantly, Lee Yoo Young's acting was so painful to watch, I don't understand how she was the main lead in multiple films and is still this terrible at her job. All the applause to Lee Min Ki who solely carried the show and did fantastic.
