I Debuted After Becoming a Sickly Female Supporting Character

Jiang Su was a highly trained assassin who died and transmigrated into the body of a nineteen-year-old girl with the same name. The original owner of this body was an orphan raised by a wealthy but neglectful stepfather, Cheng Yue, who showed no interest in her. Humiliated by the revelation that her stepfather favored another woman, Dong Jiayu, the original Jiang Su attempted suicide by jumping into a river. Jiang Su, possessing the combat skills and cold demeanor of a professional killer, saved herself and was rescued by Zhao Qiuying, a celebrity and mentor on an upcoming idol survival show. Rather than accepting the tragic fate of the original character, who was destined to be vilified and die, Jiang Su decided to survive and thrive in this new world.

After the incident, Jiang Su found herself without resources or identity. A talent manager from Sanjin Entertainment, Xu Dazhi, recognized her from the news and recruited her as a replacement trainee for the idol competition Rookie Girls. The company was in turmoil, having recently been taken over by Yan Yucheng, a young man rumored to be a fake heir who had risen from a construction site. Yan Yucheng, skeptical of the company’s declining state and his own legitimacy, observed Jiang Su with interest. When presented with a predatory contract offering only 20 percent of her earnings, Jiang Su refused to sign it. Yan Yucheng intervened, drafting a fairer agreement with a 50-50 split and a five-year term, which Jiang Su accepted. She viewed this not as kindness, but as a business transaction, calculating that she could leverage her skills to secure better terms.

Jiang Su’s training revealed her extraordinary talents. Despite her fragile, delicate appearance, she possessed perfect flexibility, dance ability, and vocal control, learning routines in mere repetitions while other trainees struggled for weeks. Her indifference to social dynamics and her blunt honesty confused those around her. She formed a tentative alliance with Yu Xinyan, a long-term trainee who had never debuted, teaching her confidence and techniques. Jiang Su’s primary motivation remained financial security and survival, though she found unexpected moments of contentment in simple pleasures, such as eating the company cafeteria’s strange food and sleeping in a comfortable bed.

During the first episode of Rookie Girls, Jiang Su’s unconventional behavior drew significant attention. When asked about her specialty, she deadpanned that riding a motorcycle over a 42-meter river counted, baffling Zhao Qiuying. In a strategic move during the self-assessment phase, she boldly chose the highest rank, A, despite the risk of severe point deductions if she failed. This decision shocked her peers and producers, marking her as a formidable competitor. Her confidence unsettled rivals like Wan Yue, who feared Jiang Su’s potential, while Yan Yucheng watched with growing amusement and intrigue.

The narrative shifts as Jiang Su’s true nature begins to surface. During a live broadcast of her dorm room, she casually disabled the camera, revealing her heightened awareness and combat instincts. Zhao Qiuying, who had been monitoring her progress, realized she was not the naive girl he remembered from the river incident. Meanwhile, Yan Yucheng recognized a kindred spirit in Jiang Su, both of them outsiders navigating hostile environments with calculated detachment. As the competition intensified, Jiang Su navigated the treacherous dynamics of the entertainment industry, balancing her assassin’s pragmatism with her new identity as an idol trainee, while Yan Yucheng sought to stabilize his company and uncover the truths behind his family’s politics.
