I watched the Korean drama Goong before reading this manhwa, so I couldn't help but compare the two. I think I like the manhwa more than the drama adaptation, because I got to see extra scenes that were omitted in the drama. The story is great; there are lots of intrigue and interesting characters. However, towards the end the story got repetitive and a bit tiring. I truly enjoyed reading this, even though I prefered the ending in the drama. If you like themes like royal issues, rich guy/poor girl and love triangle then you should read this.
The concept for this story is interesting, and the art is beautiful. However, it becomes rather redundant. The characters progress to a certain point, then it's just a wash-rinse-repeat cycle of them going through the same struggles, very slightly altered. I will probably read it to the end, but only because a friend is letting me borrow them. It's not a series I will buy for myself.
