My Sister-In-Law Is Back, and I Will Be in Charge of the Marquis Mansion with Her.

I took her identity for sixteen years and was prepared to be abandoned and sent away. But when the daughter-in-law came back, her first words were: "You have been wronged, you will be with me from now on." She protected my reputation, and I helped her run the family; she was a jealous and ruthless aunt, and I took care of my insidious concubine. Is the back house secretive? Best relative? Sorry, we sisters are of the same mind, and we have the final say in this Marquis Mansion.
