My White Moonlight Is Back, Lord Marquis, He Is Fighting for It

[Marriage first, love later + wife chasing crematorium + male protagonist's main wife position, mistress style] After being thrown into the Zhuangzi for ten years, no one cared about her. Once he took her back to the capital, he asked her to marry into the Marquis's house on behalf of his eldest sister. Deng Yuanwei obediently agreed and successfully married the prince. As a result, the next day came the news that the prince had died on the front line, and the whole family was in chaos, but she remained unmoved. Without the man, she is gone. Anyway, she only entered the Hou Mansion to find a way to detoxify him. However, they searched the entire Hou Mansion to no avail, until a man in black broke in that night when the poison was spreading. While healing him, he couldn't resist the temptation and licked the blood from his abdomen, which actually alleviated her poison. After learning that he was the prince who had faked his death, Deng Yuanwei began to talk sweetly to detoxify herself, coax him, lure him into the drama, and escape from the Hou Mansion when the matter was completed. … Cheng Yan knew that his wife had another purpose in entering the Hou Mansion. In order not to make his elderly grandmother sad, he reached a consensus with Deng Yuanwei and agreed to help her find an antidote. After her grandmother died of illness, he would let her go free and marry her with Su Yunqing, the imperial censor. But as the days went by, his eyes always stayed on her for some reason. Especially when he saw her and Su Yunqing chatting and laughing, and having a perfect understanding, he felt it was more and more annoying. Finally, when she was about to leave the Hou Mansion and spend the night with her lover, he rode out of the city with Xuan Jiawei and stopped her carriage. He asked with red eyes, "Why don't you continue to use me? How can anyone run away like you?"
