After inheriting a fortune, Gu Yang transmigrates into a novel as the fake daughter who usurped the real daughter's place and faced a grim fate. Initially, she antagonized the heroine and the villain. To ensure her survival, Gu Yang attempted to distance herself from the Gu family, apologize to the heroine, and support the villain, aiming for a low-risk existence. However, her plans unravel as the Gu family fiercely declares her their daughter and offers her a share of their business. Her brother pledges his loyalty and the Gu family's assets to her. The heroine pledges to obtain ten Gu families for her, and the villain professes his devotion of blood, people, and everything he possesses. The wealthy community initially dismisses the Gu family's favoritism towards the fake daughter. Yet, the Gu family rises to become Jincheng's richest and industry-leading entity, sparking widespread envy. When rumors circulate about Gu Yang associating with a "mentally ill" individual, netizens mock her. This draws public figures from various sectors to declare themselves her patients, and prestigious psychiatric associations reveal her as their president, causing a widespread stir. Gu Yang believed the villain, once a "little blood bank," was pitiable and deserved better treatment. Unexpectedly, he confronts her, questioning if she hypnotized him, as his thoughts are consumed by her. She later realizes he had been waiting for her throughout her tumultuous journey.
