The Heir Regrets Breaking Off Our Engagement, and All of the Capital Awaits My Choice of Husband

She spent twelve years alone in the empty chambers, only to receive a divorce letter after the marquis returned victorious. Unwilling to give up her place, she was burned to death. Reborn back to the moment her mother-in-law at the marquis’s estate pressured her to marry, she took the initiative to call off the engagement. The lovers ended up as brother and sister, yet he said he regretted it, fell to his knees, and begged her through tears: “Choose me. Don’t leave me.” Happy little puppy: “Sister-in-law, I’m your brother-in-law.” Flirtatious heir: “Money and power are the best tonics. I’ll give you both.” Brooding, jealous king: “Don’t belong to anyone else. I’ll go mad.” <Rebirth + face-slapping + male rivalry + groveling ex + strong female lead + no romance>
