After Being Reincarnated, the Female Supporting Cast Was Criticized for Going Against the Will of Heaven

She is the princess of the fairy kingdom, who is loved by thousands of people; she is an incompetent concubine from a noble family, whose father does not love her mother and does not want to suffer humiliation. As fate would have it, the princess' fairyland was destroyed, her people were massacred, her relatives died tragically, the emperor's younger brother was humiliated and committed suicide, and she herself also died tragically after knowing all the truth. Once reborn, nothing has happened yet. She wants to nip everything that happened in her previous life in the cradle, but... Why are these people trying to stop her?
