I wasn't a fan of either IU and LJK coming into this roller coaster ride(Didn't see any of there previous works). But after watching the series and completing it i can now say i am a big big fan of both actors the way the series carried itself over the streches of 3 to 5 episodes showed a different side to them and you were on the edge of your seat with there acting as was the rest of the cast. When some of there motives and emotions start to show the show really grabs at you and doesn't let go untl the end of the ride. The music and ost of this drama is really excellent one of my favorites along side Who are you 2015 Its truelly a shame this didn't do well in korea and i for the life of me can't figure out why IU was critised for her acting in it props to all the cast for the amazing roller coaster and well done this instanly made it into my top 10 dramas and found myself 2 new of my favorite actors in the process i am glad at least on the international stage it did well and it receive the real love it deserver a great fantasy history drama.
