The Villainess's Secret Voice

Margaret Lynch wakes up inside the body of a villainess from a story she once knew, a heroine-centered tale where the lead character is idealized and everyone else exists to serve her. Now stuck in the role, she is bound to the Destiny Villain System, a mysterious program that rewards her with Destiny Points for her efforts. The source of her fate is unclear, but the system makes one thing plain: she must gather those points to survive and change the course her life was written to follow.
