Ruan Ruan is a devoted fan of pop idol Ji Linhao who collapses at his concert and transmigrates into the body of Ruan Yu, a wealthy heiress and secret wife of Duan Lin, Ji Linhao's rival. Waking up in a hospital, Ruan Yu learns she is married to the man she spent years attacking online. Duan Lin, cold and indifferent, dismisses their union as a staged agreement for their families and leaves for a month-long shoot. Ruan Yu, initially shocked, decides to embrace her new life while maintaining her love for Ji Linhao. She attends his concert, where she accidentally goes viral by shouting a marriage proposal to him, a moment Duan Lin witnesses and mocks.
Determined to stay close to her idol, Ruan Yu enters the entertainment industry under the management of An Zhuoqian. Her contract includes a clause requiring her to collaborate with Duan Lin twenty percent of the time. Despite her reluctance, she trains rigorously under acting coach Zhong Xuhai, who also taught Ji Linhao. During an audition for the film Chasing Shadows, she impresses director Guan Baonian with a heartfelt performance, though Duan Lin coldly rejects her, claiming she is unsuitable. Nevertheless, she is cast in the film.
On set, Ruan Yu continues to support Ji Linhao in fan rankings, even asking Duan Lin to vote for her idol. Their interaction is tense, with Duan Lin misinterpreting her actions as attempts to get close to him. A scandal erupts when a video of Ruan Yu at Duan Lin's hotel room goes viral, sparking rumors of a romance. The internet, particularly Duan Lin's fans, attacks her, but she remains unfazed, viewing the attention as a necessary sacrifice for her idol's success.
As filming progresses, Ruan Yu navigates the challenges of her new career while dealing with the complexities of her secret marriage. She discovers that Duan Lin is the heir to Dongying Entertainment, a fact she had missed in her previous life. Despite the rivalry between their fandoms, Ruan Yu remains committed to Ji Linhao, using her new status to support him from behind the scenes. The story follows her journey as she balances her dual identity, her career ambitions, and the growing tension with her husband, all while maintaining her devotion to the star she loves.
