After rebirth, I don’t want to be a Mary Sue heroine anymore!

As the Mary Sue heroine that everyone envied, my life was very complete. I had a powerful father who loved me, and an emperor who loved me alone among the three thousand beauties. My life was simply the heroine that everyone envied. But what people didn’t know was that I died after only being the queen for eighteen days, and my father who loved me so much was not sad at all when he saw me die. After my death, my body was devoured by the fire, and nothing was left of me. Another woman entered the palace to replace me and enjoyed everything that should have belonged to me. I thought they couldn’t stand my departure and found a substitute, but later I found out that I was the substitute of that woman. In my next life, I want to take back everything that belongs to me...
