Originally, I expected this Drama to turn out like all the others; just a love story that hits all the major cliches and ends when the two main characters finally get together. After the first episode, I became OBSESSED with this show. It was amazing. The cinematography was perfect, the story was well written, and the actors fit their roles well. The best part about its drama was definitely the characters and their relationships. I love how the writers developed each of the main characters, but not so much that they were predictable. They grew along with the story, changing for the best, but also remaining true to their original selves. Character relationships grew in complexity and each one of them served a different purpose throughout. There are very few dramas or TV shows that add so many sub-plots within the story. Normally, there's just one main plot line and two or three smaller sub-plots that rarely appear in all the episodes. However, this drama had quite a few and managed to show the watcher how it was progressing in every episode. I think that's what really made this show shine. Lastly, I really loved the emotional value of this drama. It made me laugh, cry, scream at the screen and tear my hair out in frustration- all at once. Kudos to the writers for managing that. There were a few parts I thought could have been done better; for example, a few character motives didn't quite make sense- but overall the King 2 hearts is really a masterpiece. There is no doubt that I am going to rewatch it.
