Transmigrated as the Younger Sister of a Hidden Identity Boss

At the start of the story, she framed the true heiress and the female protagonist, forced the villain to serve as a blood bank, and offended every single protagonist and antagonist alike. In order to survive until the end, Gu Yang decisively drew boundaries between herself and the Gu family's toxic members. She apologized to the female protagonist, replenished the villain's blood, relied on herself, and stopped seeking death. However— Father Gu and Mother Gu: "No matter what, Yangyang is still our Gu family's daughter! The Gu Group also has a share belonging to Yangyang!" Younger brother Gu Pei: "I only have one sister, Gu Yang! Sister, I'll give you the entire Gu family!" Female protagonist Gu Jin: "What does the Gu family matter? If you want ten Gu families, Sister can get them for you." Villain Feng Jue: "My blood, my person, my everything—it all belongs to you." ………… In the private circles of Jincheng's wealthy elite, people whispered, "The Gu family is full of fools, treating that fake heiress like a treasure." Until one day, the Gu family leaped to become the wealthiest in Jincheng and the industry leader. Everyone grew envious. Hearing rumors that Gu Yang spent all day hanging around a mental patient, netizens mocked: "Is she probably a psycho too?" Big shots from all walks of life stepped forward one after another: "I am her patient." The Chinese Psychiatric Association and the Psychological Society: "She is our President." The entire internet exploded. …… Gu Yang thought the little blood bank was handsome and a pitiful soul, so she decided to be kinder to him and compensate him more. Until one day, the little pitiful soul pinned her against a corner: "Did you hypnotize me? My head is filled with nothing but you." Only later did she realize that while she had been wandering through the mortal world, he had been waiting for her all along.
