After being reborn and marrying into a duke's household, I'm being tormented daily by my cold-hearted mother-in-law, but it seems there's something hidden behind all of this.

# A Corporate Slave Who Died from Overwork is Reborn as the Second Daughter of a Poor Viscount Family Overworked corporate slave Elianna is reborn as the second daughter of an impoverished viscount family. Through a political marriage arranged for her family's sake, she marries into the Falkenberg Duchy—a noble house on the brink of collapse. Her husband is the "Ice Prince," and her mother-in-law is an empress feared as the "Ice Wall of High Society." She braced herself for terrible in-law harassment, but using her complaint-handling and business improvement skills honed in her previous life, she unexpectedly streamlines even the harassment!? "Mother-in-law, I have a proposal for improvement." Eventually, she becomes aware of a grave fraud eating away at the duchy, and... A former corporate slave uses her skills to win the trust of her ice-cold husband and formidable mother-in-law, rebuild the family, and pull off a thrilling reversal story!
