My name is Jian Ning, and I am the "fake daughter" who has been raised by the top wealthy Jiang family for twenty years. Everyone knows that the real jewel of the Jiang family is sister Jiang Ruoxue. She is beautiful, outstanding, and popular among all the stars. She is the Plan A of the marriage between the Jiang family and another wealthy family, the Lu family. As for me, I was just afraid that something would happen to my marriage, and the Jiang family would push it out as a "failed plan" - Plan B. My mission is simple: be a good foil for my sister, quietly serve as a backdrop at the engagement party, and then disappear completely with a sum of money given by the Jiang family. This was my original plan. I knew the script by heart and was just waiting to take the money and leave to start a new life. As a result, on the day of the engagement party, her sister Jiang Ruoxue eloped for love. He ran so vigorously that he even left a letter denouncing business marriage as feudal dross. The whole place was in an uproar, the Jiang family and the Lu family were disgraced, and the multi-billion dollar cooperation project was in jeopardy. When everyone was panicking, my nominal father looked at me for the first time and said in a commanding tone: "Jian Ning, come on." So, amidst everyone's sympathy and ridicule, I, the spare tire, succeeded in taking over and married the legendary Lu Jinyan, the heir to the Lu family who was ruthless and cold as ice. Married life be like: Lu Jinyan: "This is an agreement. We each get what we need and we don't interfere with each other." I nodded like garlic: "Okay hubby, I got it, no problem hubby!" The Jiang family: "As long as you hold Lu Jinyan steady, the task will be completed." I smiled: "Understood, I will be a good mascot for Mrs. Lu." However, they didn't know.
