The betrothal gift is two million bucks, not a single cent less. Jiang Yu is already eighteen years old and can get married now. Send the money to my card, and this matter is settled!" Jiang Yu looked at her mother, who was talking non-stop on the negotiation table. She watched as her mother named her price as she sold Jiang Yu. Jiang Yu could not believe it. Eighteen years ago, they brought the wrong baby home from the hospital, and Jiang Yu, the real daughter of a wealthy family, ended up in an orphanage until a year ago. Jiang Ran, the fake daughter of the Jiang family, grew up with a silver spoon in her mouth. With superior resources since she was young, she was more outstanding than Jiang Yu in every aspect and became the pride of the Jiang family. Jiang Yu, who wandered most of her time in the outside world, was nothing but a country bumpkin who made her mother a laughing stock in the socialite circle. However, Jiang Yu had no idea how great her mother's hatred for her was. On the day she turned eighteen, her mother 'sold' her with a named price. Jiang Yu said, "If you want to marry your daughter to someone else, it should be Jiang Ran. I'm your real daughter. You're the one who mistakenly brought Jiang Ran home!"

From then on, the thirty-year-old man pampered his eighteen-year-old wife to the heavens. The little girl said, "Mister, someone bullied your wife!" The man, "Which incompetent fool is so blind that he dares to bully you?"
