After transmigrating into her favorite novel as Ethel Wallace, she realizes how ridiculous everyone is to fawn over Riena Cassius, her sister-in-law and the original female lead who regressed in the story. Ignored by the family and unable to endure the nonsense any longer, she is determined to divorce her husband and turns toward the marquis, Riena’s future enemy, for help. Will Ethel escape House Cassius? Or will regression trump transmigration? And why does the marquis seem… like a gentleman?
