I Will Divorce the Female Lead's Older Brother

After transmigrating into the pages of her favorite novel as Ethel Wallace, she quickly discovers the absurd reality of her new life. Everyone in the household fawns endlessly over Riena Cassius, her sister-in-law and the story’s original female lead, who has mysteriously regressed back in time. Meanwhile, Ethel is completely ignored by the family, left to endure their senseless devotion to a woman whose future actions will bring ruin upon them all. Refusing to tolerate this foolishness any longer, Ethel resolves to sever her ties with House Cassius by divorcing her husband. To achieve her freedom, she turns to an unlikely ally: the marquis, a man destined to become Riena’s greatest enemy. By aligning herself with him, Ethel hopes to finally escape the toxic environment that surrounds her. However, securing her independence may prove far more complicated than anticipated. As she navigates this dangerous game, one pressing question remains—will Ethel successfully break free from the Cassius family, or will the power of regression ultimately overpower her knowledge as a transmigrator? Complicating matters further, the fearsome marquis she sought out for aid seems unexpectedly like a true gentleman.
