This is a very beautiful story.

Tells about the struggle for independence in Korea during the Japanese colonial era.
But not too complex and tends to be taken towards dramatization but written and presented very beautifully.

Initially, this drama seemed easy to predict because the author scattered clues here and there.
But it turns out there are many stories that hidden by the author. Every important scene is only opened in several parts, not in its entirety. It opens slowly, so that the audience can imagine and guess the future plot. But in the end a twist awaits ahead.

And I really love how they end every single episodes. A twist then soundtrack hit and its done well. Wow......beautiful.

The weakness of this drama is in the ending.
The ending must done better.
The writing seems a little rushed. As far as I know, some dramas are shoot and the ending is written while the drama is being broadcast. So there are a lot of weak points at the ending.

But yeah, overall it still deserves a 10/10 because it's that good.
Bravo.
