Could you please recommend a K-drama or movie where a royal or higher up person falls for someone who is a servant/maid/lower class civilian?
From what I remember, there are these:
Sungkyunkwan Scandal
Tamra, the Island
Flower Crew: Joseon Marriage Agency
Love in the Moonlight
Not sure about the last 2.
Best example is Dong Yi but it so long... but good drama.
Jejoongwon? None of them are royals, though. The female lead is from a family of (well-to-do) merchant; one of the male leads is a butcher (an "untouchable", basically), while the other male lead is a nobleman.
