The storyline is very captivating. Initially it takes time to understand, after few initial episodes, they were really awesome. The plot is very different and preety far from most of the k-dramas. You can see a different Lee Min Ho, whose acting was so matured and all I can say is no one would have suited well for the role other than Minho. He really lived like a king in this drama. Overall a rollercoaster of love science and emotion. It's worth the watch
