Yeah, this is what a great drama looks like, it's amazing.
It kind of remind me of The Untamed (that continues to be the best), but with some dragging episodes and more investigation cases.
Amazing actors, really, the main actors are everything, I like them all.
The main story is so good!!! It even has some major plot twists I wasn't expecting for.
The plots and the characters made me happy, sad, anxious, excited, such complex feelings that only a major drama can get out of you. I was fascinated by the main characters relationships, I could not stop watch and wonder what was going to happen next. The end made me sad, but it's a good end.
The OST is beautiful.
The production is consistent, very well-made.
There are two things to consider:
1. Romance it's definitely not the focus, don't watch looking for that.
2. There are some episodes that you want the main story to develop, but they spend too much time on the side stories and the drama became a little draggy.
Overall, 10 out of 10.
