I wasn't really planning to watch this drama due to the historical factor, but someone thankfully persuaded me to watch this and I don't regret it at all. It's the first time I'm seeing Kim Nam Gil and Kim Ah Joong in any drama, and I'm surprised at how much I liked them here (especially Kim Nam Gil, *wink, wink*). I got pulled into the story in the first episode itself, considering that I've dropped a lot of other dramas in the first episode, but this show started and ended on a good note with me. Also I love how the show leaves you confused and wanting to continue watching.
 If you're looking for something unique, and something romantic but at the same time with a good plot and enough humor to keep you invested, you can be assured that this is the one for you. You definitely won't be disappointed with the cast, they're remarkable, and might leave you wanting more from them.
I promise you'll fall in love with Kim Nam Gil, and especially his funny expressions.
I left this drama with a lot of inspirational lines, and this show definitely changed my perspective on a lot of things.
Also, the OST is a plus. It's been a long time since I downloaded all the songs from a drama.
