I'm Spoiled by Real and Fake Money

On the day I was admitted to a wealthy family, my mother put a black card into my hand and comforted the fake daughter. My brother hugged the fake daughter's shoulders and warned me coldly, "Don't try to take things that don't belong to you." Even my fiancé, who was engaged to marry me, stood opposite to protect the fake daughter and said, "You just came back, so don't be too aggressive." Others would have red-eyed vying for supremacy, but I just want to show it off: take the black card and spend it as I please, and don't get involved in any family affairs. Whoever wants to be the heir to the wealthy family who wants to work hard can be the heir. But the more I lay down, the more outrageous the plot became - my parents were watching me every day to be afraid that I would run away, my brother took the initiative to send me resources and begged me not to be alienated, and even my fiancé, who was protecting the fake daughter, helped me stay out of trouble. Looking at the fake daughter who was jumping anxiously, I leaned on the sofa and chewed some fruit and sighed: If I had known that I could win by showing off, who would have bothered with the female competition?
