The Domineering President Fell in Love with My Mother

My mother suddenly announced that her true love had arrived, and she married me into a wealthy family in a flash marriage. When I woke up, I had a cheap father and a cheap brother, and when I went to sleep again, I found that I was the vicious female supporting character in a certain novel. This world is really fascinating. I planned to use my father's money to become a little bitch, but I didn't expect to meet a poor little girl. She was good-looking and had a good personality. More importantly, she could call her sister, which was definitely a cover. However, God's will is to force some kind of sadomasochistic love, so let's do it. I hope I don't torture the poor little one I'm covering to death!
