Burn The Queen Down

She wants a chance to do something about her elder sister, and she does not get one. She is already dying when she learns the truth. The sister, who has become Empress by then, was never their parents' child, and she is the one who killed the whole family. Years earlier that sister had been promised to a sick man, in a marriage arranged in the hope that a wedding would cure him. She was afraid of being left a widow, so she arranged for her younger sister to go in her place. The groom recovered. The sister then changed her mind about the match and let it be known that the younger one had stolen her husband, and the younger one was despised for it until she died. She wakes up on the day before that wedding. This time she pulls the sister's mask off in front of everyone and turns down the match, one everyone envies, and the sister is left to regret it. After that she turns to the people who destroyed the family, and she does not stop for the ones who get in her way.
