Gu Nanci, a top-tier global idol from Blue Star, dies in a hospital bed after a long illness, only to awaken in the body of a disgraced teenager on the Hongluan Continent. This new Gu Nanci is a sixteen-year-old girl disguised as a boy, forced into the entertainment industry by her abusive uncle, Gu Zhaofeng, to fulfill the debut contract of her missing twin brother, Gu Nanjue. The original owner was a frail, sickly girl with no talent for singing or dancing, universally hated as a "pretty vase" who coasted on her appearance while being bullied by teammates and slandered by rivals. On the night of the "Fire Debut Battle" live stream, Gu Nanci is brutally beaten by her cousin Gu Xiao, who seeks revenge for perceived stolen opportunities. The assault leaves her for dead, but upon regaining consciousness, Gu Nanci discovers she has inherited the original owner’s body—and her own past-life memories and skills.
Realizing she is now a female in a male-presenting idol’s body, Gu Nanci faces an immediate crisis: the five-million penalty for breach of contract if the substitution is exposed, and the physical abuse from the Gu family. Instead of cowering, she asserts dominance over Gu Zhaofeng, threatening to reveal the truth unless he pays for her medical care and withdraws Gu Xiao from the competition. She transforms her appearance, cutting her hair and discarding the baggy clothes that hid her figure, revealing a breathtaking, god-like beauty that captivates everyone who sees her. At the debut battle venue, she confronts Si Chang, a rival who rose to fame by manipulating public opinion against her. Gu Nanci publicly demands an apology, shocking the internet and sparking viral trends that shift the narrative from pure hatred to bewildered fascination.
Inside the studio, Gu Nanci navigates a hostile environment filled with contestants who view her as a liability or a target. She forms a tentative alliance with Wen Jiuyi, a skilled dancer who despises Si Chang’s manipulative behavior, and observes Cheng Yang, a vocal specialist with a sharp tongue. The production team, led by director Fu Zhi, initially plans to use Gu Nanci as a scapegoat to generate controversy, granting her a "bye" in the first round to avoid her potential failure on stage. However, Gu Nanci sees through the scheme, recognizing that the company intends to sacrifice her reputation for ratings. Rather than accepting this role, she begins preparing for the upcoming group performances, determined to prove her capabilities.
With limited funds, Gu Nanci turns to her hidden talent as a composer. She uploads a demo song titled "Hate Me, Love You" to a music trading platform, selling the rights for a substantial sum to a struggling idol group in need of material. This financial windfall allows her to secure basic necessities and focus on training. She arrives early for practice sessions, surprising her peers with her dedication and natural talent, which contrasts sharply with her previous reputation as a lazy celebrity. As the competition progresses, Gu Nanci prepares to dismantle the lies surrounding her identity, expose the bullying by the Gu family, and reclaim her place on stage—not as a substitute, but as a legitimate artist in her own right.
The story follows Gu Nanci’s journey as she balances the dangers of her double life with the pressures of the entertainment industry. She must hide her true gender while competing against rivals who would destroy her if they knew the truth. Her past-life experience as a world-renowned idol gives her an edge in performance and composition, but her current physical weakness and the constant threat of exposure create high stakes for every move she makes. As the debut battle intensifies, Gu Nanci begins to turn the tide against her detractors, using her beauty, talent, and sharp wit to challenge the power structures that sought to keep her down. The narrative explores themes of identity, resilience, and the ruthless nature of fame, as Gu Nanci fights to survive and thrive in a world that has already written her off as a failure.
