I vaguely remember a story about a queen giving birth to twins, but one twin, for whatever reason, was sent off to be put to death. But the person tasked with that couldn’t live with it, so they entrusted the baby with someone else to raise. And of course, this twin came back into the succession picture at some point. But that’s really all I remember of the story. I can’t even remember if the second twin that was sent away was a boy or a girl, though I think it was a girl. I feel like this fits your emojis, but I really can’t recall what drama. Maybe it will ring a bell for someone else.
Edit: I put it in spoilers in case anyone wants to really figure it out from the emojis, without additional info.
Clue 1: royal couple has 2 babies (twins?)
Clue 2: twins not accepted, only 1
Clue 3a: baby 1 is a royal
Clue 3b: baby 2 has no money / is poor
Clue 4: princess dead & poor girl becomes princess
Clue 5: person with crown who isn’t princess (or queen?) is angry
Clue 6: Not North or South Korea, (go back in time) historical Korea
I have an idea, but let’s keep going… I’ll skip @my_happy_place 's clue till the end
Clue 3c: baby grown up as a child speaks Korean, Chinese and maybe more?
Clues 6a to 6d are really cementing the idea I have
Clue 6a: supervillain woman with crown, not queen, is married to older king, king dies
Clue 6b supervillain couples with king, but he doesn’t want to marry her, so king gets crown taken away to supervillain’s content
Clue 6c: Soldier (higher rank than soldier?) is in love with supervillain
Clue 6d: supervillain is the nr 1 and teacher of the Hwarang
I’ll blur everything in case @lutra also wants to try.
Amusing, I might not have been able to guess if I didn’t watch it
My answer: Deokman aka Queen Seondeok
