The Whole Galaxy Calls Me Vicious, but Five Commanders Fight to Spoil Me

After dying in the apocalypse, Calista wakes as the hated villainess of an interstellar novel. The original Calista humiliated five commanders and was exiled to a polluted planet. She only wants to make amends and go home. When a beast horde attacks, her power purges the army's corruption without side effects and shields each soldier. The galaxy still calls her vicious. When the true heroine arrives, Calista plans to leave, but the five men who should hate her are all racing to stay by her side.
