Reborn at Five and a Half, I Help My Mother Marry the Warring Prince

In her previous life, she watched the wicked mother and daughter her father brought home torment her and the Marquis's principal wife. At eight, she saw the wicked woman whip and poison the principal wife, who died a cruel death in the snow. When she came of age, her stepsister murdered her without mercy. As she lay dying, she saw a tall figure hold her and say he had come too late. He had failed the promise he made to her birth parents, letting her suffer terrible injustice, and he would avenge her. When she opens her eyes again, she is five and a half, back on the day her father brought the wicked mother and daughter home. Now she will expose her father's hypocrisy and help the Marquis's principal wife remarry the Prince of War.
