I Married the Beast, and the Prince Regretted It

Princess Eloise of Osilia was poisoned and disfigured while saving her childhood love, Prince Carlos of Lancaster—only for her sister Selena to steal the credit. Carlos fell for Selena, but still planned to marry Eloise so she could face danger in Selena's place. Heartbroken, Eloise switched places as the brid and chose to marry Altan, the feared lord of Varga. On the wedding day, the antidote restored her beauty, and Carlos realized she was the one who had saved him.
