Reborn to Seize the Marquisate: My Imperial Uncle Has My Back, and I’m Hooked

[Rebirth + family intrigue + no forgiveness + sweet romance] A sharp-tongued, taciturn male lead vs. an outspoken, clearheaded female lead Jiang Yun Zhao saved the crown prince, earning her marquis household promotions, wealth, and glory. After she was injured and spent three years recovering, her husband's family secretly adopted a legitimate son without telling her. A female cousin also moved into the household and brazenly claimed everything that belonged to her. They ruined her reputation, crippled her, and left her to freeze to death on a snowy night. Reborn on the eve of her return to the marquis household, she slew bandits and wicked servants, then came back with blood on her hands. This time, she'll reclaim everything that belongs to her and live life on her own terms. Outnumbered and outmatched, she strikes a deal with her uncle, the prince, who is suffering from a deadly poison. The prince says, “Who gave you the nerve to bargain with me?” Jiang Yun Zhao replies, “Your Highness's life did!” The prince agrees. With her goal achieved, the prince still delays making good on his promise. “Establishing a household in your own name is impossible, but you can become a widowed consort!” Jiang Yun Zhao says, “A widowed consort sounds wonderful. Just what I've been hoping for!” That way, she can keep her property openly, and no one will dare covet it. The prince really is a good man. Who could have guessed that the supposedly late Prince Xian would suddenly show up? “Thank you, Uncle. Your nephew is willing!” Jiang Yun Zhao: “...” But I'm not! The prince says, “There must be a mistake! The emperor has already arranged your marriage!”
