I accidentally clicked on episode one of this kdrama on Amazon prime. Didn't think that I would get hooked immediately. I usually watch a 16 episode dramas only. Then I realized after episode one that they were 50 more episodes to go! Oh my! Like I would totally have to retire to finish watching the rest of this! But it's so amazing that i finished it in 6 days with a lot of lost sleep!!!! It is THAT GOOD!! Great acting with all good and bad characters! The emperor is visually stunning! Main actress does not disappoint! Beautuful and tragic drama! In even if you don't like long dramas this one is worth it!
