After Rebirth and Marriage Change, the Duke's Wife Went Crazy with Murder

Born twins with my sister-in-law. When she opened her eyes, she found that she was reborn on the day of her wedding. Her sister-in-law wanted to switch marriages, and then she learned that she was not the only one who was reborn. My sister-in-law wanted to marry that down-and-out prince simply because his official position was getting higher and higher in his previous life. On the other hand, the Duke's Mansion was at its peak, but after March his whole family was exiled to the border, so he planned to change marriages. But who knew she was unwilling? By marrying into the Duke's Mansion, she no longer has to deal with a mother-in-law who can't understand what she's doing, nor does she have any of her best relatives coming to challenge her, or her sister-in-law who makes things difficult for her. Where can I find such good things? Moreover, after being reborn, how could the Duke's Mansion be exiled in this life? She wanted to take a closer look at the marriage that her sister-in-law had personally arranged to see if it was what she wanted. It's just that the indifferent husband is getting more and more clingy to him.
