So it took me 5 days to finish the first 9 episodes and 2 days for the last 11 episodes. It was pretty good drama. At first I didn't like it. I didn't understand what was going on. So I was gonna drop it after watching 3 episodes. But somehow I didn't dropped it and kept watching. Then again when I was in the 10th episode I thought that let's not drop it just put it in hold, take a break and start watching it again after few days. But OMG. From the 10th episode the story became so much amazing and enjoyable. It kept getting better and better with every episode. As I said I finished the last 11 episodes in 2 days. The story seems so slow in the first and it keeps getting better as the show goes on. There was so good action/fighting scenes. I also laughed very much watching the show. Some scenes was so well thought. I didn't like the comedic approach from the characters to be honest. But some people might like it. So overall it is an drama that's definitely worth watching. But you need to have patience as the story is kinda boring in the first. And there was some unwanted scenes just to make the drama longer. You can skip some scenes if you don't like it. And the drama is usually longer than other dramas. Each episode is longer than 80 minutes. So yeah as I said you need to have patience in the first few episodes only after that you will love watching it.
