At first, i never thought i would love this drama. I don't know anyone from the cast. But the storyline was different. It was a great drama cause of it's twists and turns. Makes you want to watch the next episode immediately. I was quite disappointed when this drama didn't win the best drama for 2016. Most of the people who didn't vote for this are only into love stories or romcom series. Anyway, hope many would watch signal and make recommendations.
