My Brother's Cursed Bride

In her past life, Vivian Lynn, eldest daughter, was to marry Leo Shaw. On her wedding eve, Leo brought home Chloe Lynn, claiming she was the true heiress. The Lynn parents swapped brides: Vivian married Leo's older brother, Xavier Shaw, cursed to kill his wives, while Chloe married Leo. Vivian forced Leo to marry her, suffered his cold shoulder for three years, and died resentful. Reborn, Vivian decisively takes Xavier Shaw's hand, becoming Leo's sister-in-law.
