Watch Your Mouth, Saint!

Roella Brietta is a fake saint destined to be replaced by the real deal, until a mysterious system traps her in a forced redemption route: raise her reputation or die trying. She plans to lay low, but her reluctant good deeds keep being mistaken for real power. Things spiral further when the crown prince, tormented by a secret curse, realizes her touch can ease his pain. Now, with her quiet plan slipping out of control, Roella had better watch her mouth... because the system is always listening! (Source: Tapas)
