Luo Ou and Tang Mi (played by Li Xinran) are twin brothers and sisters who are as close as brothers. In their early years, they lost their parents and have been living a life of dependence on each other. Luo Ou, who has a handsome appearance, was discovered by a scout and entered the entertainment industry. Unexpectedly, he became a big star overnight, while Tang Mi seemed extremely ordinary under the shining starlight of his brother and has been living a quiet life. An accident caused Luo Ou to fall into a coma. At this time, Tang Mi stepped forward and inherited her brother's dream. She disguised herself as a man and replaced her brother's identity to participate in the talent show. She successfully advanced, won the role, and joined the crew. Here, Tang Mi met her former senior Yang Han (played by Xu Zhenyao), but it is obvious that Yang Han, who is now a big star, has long forgotten who Tang Mi is.
