The Lion King's Palm Queen

Ultra-Fertile Snow-Flop Rabbit Ella gets her whole clan killed after being framed by her evil sister and trash husband Caine. After her rebirth, she rejects Caine and proposes to Acting King Arthur, and he says yes. On their wedding night, she finds Arthur is far softer and more loyal than the rumors claim. With Arthur's full protection, she exposes Caine as a fake pureblood, gets revenge, becomes the dominator, and rules happily ever after with Arthur.
