Does this drama has a happy ending? I don't want to read the comments and be spoiled so if someone can just reply me yes or no that would be great. Thanks!
Watched the first episode and after doing some googling of the real history it seems that the younger sister will become the first empress who then get deposed. I can't stand the standard trope of villainess sister betraying the main character. I hope that wont happen here... For now, I'm going to hold off watching this drama.
