The Wealthy Sister of Top-Tier Twins

Sang Ji is a wealthy businesswoman who recently returned to China after years abroad. She is the older sister of twin brothers, Shen Xi and Shen Ci, who are top-tier traffic stars in the entertainment industry. Upon waking, Sang Ji discovers two conflicting systems in her consciousness: a Villainess Counterattack System urging her to become a female lead, and a Cannon Fodder Male Lead Salvation System tasked with saving her brothers from tragic fates. She learns that her world is based on a novel where her brothers are doomed to career ruin and blacklisting due to the interference of an illegitimate daughter and a female lead. Sang Ji dismisses the villainess plot as nonsense but accepts the salvation mission to protect her family from the predicted disasters.

Sang Ji intervenes in her brothers' careers by joining the variety show "The Sibling Formula" alongside Shen Xi and Shen Ci. This move shocks the industry, as the twins had publicly distanced themselves from each other and were rumored to have a hostile relationship. The production team had originally planned to pair Shen Xi with actress Liang Shiyu to boost her profile, but Sang Ji's presence disrupts these arrangements. Liang Shiyu, aware of the original plot where she manipulates Shen Xi into dependency, attempts to maintain her gentle persona while secretly plotting to secure her position. She invites Su Tang, a newcomer and sister of tech CEO Su Ye, to join her team, hoping to leverage Su Tang's wealthy background.

During the show's filming, the guests participate in competitive games to determine their living conditions and rewards. Sang Ji's group dominates the challenges, displaying their wealth and talents. In one instance, Sang Ji reveals a custom-made watch worth eighty million yuan, silencing critics who questioned her background. The twins also showcase their skills, with Shen Ci demonstrating his dedication to acting and Shen Xi displaying his athletic abilities. The siblings' close bond and mutual protection become evident, contrasting sharply with the public perception of their estrangement. Shen Xi and Shen Ci develop a protective rivalry, each wanting to prove their worth to their sister.

As the show progresses, Sang Ji navigates interactions with other guests, including Jiang Siwei, a rival actor with a history of conflict with Shen Ci, and Jiang Rui, an influencer known for flaunting her wealth. Sang Ji remains indifferent to the entertainment industry's politics, focusing instead on ensuring her brothers avoid the pitfalls outlined in the novel. She maintains a calm and composed demeanor, using her resources and intelligence to counter any attempts by others to undermine her family. The systems in her mind continue to offer advice, but Sang Ji largely ignores them, relying on her own judgment.

The narrative highlights the tension between the predicted plot and the actual events. Liang Shiyu's schemes begin to unravel as Shen Xi rejects her advances, and Shen Ci remains aloof from the industry's drama. Sang Ji's presence acts as a stabilizing force, redirecting her brothers away from the tragic paths foretold in the book. The story sets the stage for further conflicts as the twins' careers continue to rise, defying the original narrative's predictions of downfall. Sang Ji's role evolves from a protective sister to an active participant in shaping her family's destiny, challenging the forces that sought to control their lives.
