This was an amazing drama from episode 1 till episode 19. But the last episode was very disappointing. The story and the acting was just phenomenal, but the writers screwed up with the ending. It did not make sense how the original queen ended up happy together with the king. It should have been Mr. Queen and the king ended up together and ruled till they turned gray-haired. Only then, after dying from old age, should Mr. Queen have returned to his future self. Other than that, I enjoyed the ride. I would have given the story and re-watch value 10 too, if the ending was different.
