I definitely agree that Moon Lovers was amazing! I loved everything about it :-) here are a couple more kdramas that I personally enjoyed. hope this helps! ^_^
Save Me (psychological, arguably one of the best kdramas this year)
Age of Youth (slice of life)
Weightlifting Fairy Kim Bok Joo (romcom)
Defendant (mystery, thriller, law)
Duel (sci fi, thriller)
I Remember You (mystery, detective)
38 Task Force (investigation, comedy)
+ Healer (romance, action, thriller)
edit: if you don't mind ongoing dramas, I recommend Witch's Court and Avengers Social Club. both are awesome so far. ;-)
