After Being Reborn, I Was Adopted by the Villain [Book Transmigration]

Zhou Xiying read a transmigration novel and discovered that one utterly insignificant supporting female character had exactly the same name as her. This character didn't ruin her own life, but her villainous father managed to get her killed. --Only three chapters in, she was kidnapped and killed by one of her villainous father's business rivals! Just as Xiying was about to see how the male lead would finally kill off the villainous father, she transmigrated into the very novel she was reading, becoming that same-named supporting character who died right at the beginning... Xiying had only read fifteen chapters and knew nothing about what happened next. All she knew was that she was going to be killed, and she trembled in fear, shrinking into a little quail! The one lucky thing was that the day she transmigrated was the day the character was about to be adopted from the orphanage by her villainous father. There was still time to change the fate of being killed! To stay alive, Xiying vowed to stay far away from her villainous father and remain at the orphanage!! But by a series of mishaps, Xiying still managed to get herself adopted by the villainous father. She also somehow brought the female lead into the family, making her own older sister, while the great villainous male supporting character turned out to be their older brother... What kind of nightmare scenario is this T^T She never read the ending, but she can guess that the villain and the male lead will turn against each other over the female lead. Is it still in time for her to win the female lead over, or get her villainous older brother to straighten up? A death-fearing girl who cherishes her life, especially afraid of losing her older brother, X a villainous older brother who picks fights with the whole world and is obsessed with his little sister P.S. The female and male leads aren't blood-related. They're adoptive siblings~
