The most incredible detail of ep11 was that history has always played out like this, but the history books have always gotten it wrong. Historians believed it was the King that killed his palace court, but it had always been his Uncle. Everyone just thought it was the King, because he wore the mask. And so, Jiyeong had been there in the past, in every time line, in a loop, in continuum, making sure the King didn't become a tyrant... only for the uncle to cause the revolt instead.
History could never be changed by Jiyeong, because she has always been a part of it. She isn't from the future. She's from back then and always have been.
The tyrant was never the king.
