The Unremembered Vow

Synopsis of The Unremembered Vow: A paladin, a noble, and an elven prince are cursed into stone. The witch heroine saves them by signing a cursed marriage contract: if they refuse to marry her in five years, they turn back to stone permanently. She protects them for five years, but the forest witch disguises herself as a weak woman and turns them against her. They betray her, take her staff, and break her heart. She leaves and accepts the Demon King's invitation—discovering he's the boy she once saved. The curse reactivates. The three beg for forgiveness, but it's too late. The heroine awakens her divine blood, defeats the witch, and becomes the Princess of Light, staying with the Demon King who always stood by her.
