My opinion of this series is particularly good, despite the fact that I started watching a priori it with benevolence, as Lee Min Ho is one of my favorite actors.
Parallel worlds? Past and / or future? Kingdom or republic? A ruler or just a man in love? A cop or rather of a woman in love? Bodyguard or more of a goofy guy?
Great character the power-hungry relative and head court lady.
Time gate in the bamboo forest, white horse, great costumes, well-followed scenario.. okay.
I was "bought". I also like that the ending actually stayed open.
