After Rebirth, My Younger Sister Competes to Be a Stepmother

I risked my life to move reinforcements for the emperor, and was made a princess and married into a prince's mansion; but my sister was abducted by the rebels and became a military prostitute. I tried my best to rescue her, but because she was jealous of me, she set a fire and died together with me. After rebirth, when the emperor asked who was willing to deliver the message, my sister stepped forward first. "Sister, in this life, I should be the wife of the Hou family." I smiled, just as she wished, let her be the unjust stepmother.
