It was really good drama and had potential until they left us for months (still waiting) with no ending episode. At the beginning I rated this drama 9/10 but now I need to lower my rating ?.
Whoever wants to watch this I don't recommend since 9th episode was released in late January and it's late June and we still don't have final episode. If you want to save yourself some nerves don't watch it or maybe if they magically give us last episode but until that time no need to rush to start watching this.
