Its acceptable because all the struggle they faced during this whole journey but still they managed to produce a decent Watchable drama in the end. I felt the end seems very forced but apart from that i liked the whole drama.

As you all know they changed the main actor in the middle so from there it's looks like a complete different type of show, i still remember the cuts of 8 and 9th Episodes looks really wierd. Accepting a new actor in the place of jisoo was not easy, But somehow Na in Woo and Kim so hyun chemistry looks very cute and interesting, so it was good watching them together atleast.

Coming to the story and screenplay, it has nothing particular to offer and looks pretty much a usual type historical drama with patriotism and politics. 20 long episode was understandable the very first they slowly and internationally creating a very hard chaotic environment and for a viewer, u will feel very complicated and tensed in the end the whole thing was messed up.

Everything was exactly happen what u expect, But it could have been a better ending. I read some comments that the end was not exactly from the original novel. Anyway happy to see kim so hyun with her cute acting which makes other things forget also hats off to the cast and crew especially the producer who not just reshoots the rest of the Episode from where jisoo left and also from beginning to the sixth.

Overall a watchable drama
