Lu Yanshen, the "living king of hell" in the financial empire, urgently needs a wife with a clean background and an obedient wife in order to win the trust of his family. He chooses librarian Su Wan, a quiet girl struggling to repay huge debts. A contract, everyone gets what they need. He thought she was docile and could be bullied, but he didn't know that she wrote an anonymous column every night, analyzing his "tyrannical behavior" incisively and vividly, and became an expert on love and marriage psychology who was followed by the entire Internet; she thought he was cold and ruthless, but she didn't know that in the secret room of his study, she collected all the award-winning paintings from her student days. When the contract expired, he tore up the divorce agreement: "I will decide the rules of the game." She took out the pregnancy test form and the backstage screenshot of the anonymous column, and smiled slightly: "Mr. Lu, this time, it is my turn to acquire you."
