First of all it has a melodrama tag so most people like me will skip this drama. But just because of namgoong min I gave it a try. As expected first 2 episodes were kind of melodrama. But I still continued for another 2 episodes. That's when things started to go south . Episode 4 I was crying like hell . I was invested in this . This is not just melodrama. It was action , gore , thriller . Now I realised why namgoong min accepted a period drama.
It's nothing like romantic period drama where main characters love each other and will get a happy ending and all. This is serious every character is well written. It's a must watch.
