"Star Entertainment" is China's top entertainment company. Boss Chen Tianhao and Du Wanqing used to be a loving couple, but now they are in a marriage crisis because of their different business philosophy. Yang Zhenzhen (played by Wu Qian), who loves music, joins "Star Entertainment" and becomes the assistant of the popular singer Zheng Boxu (played by Huang Zitao). Zheng Boxu is an idol singer with an arrogant and unruly personality and is difficult to control. Yang Zhenzhen gradually gets to know Zheng Boxu in the process of getting along with him, helping him to correct his shortcomings, develop his strengths, and eventually become a singer with real strength. Yang Zhenzhen herself has also transformed from a workplace rookie to a mature agent. Du Wanqing sets out to train the newcomer Yu Zirui (played by Niu Junfeng). Yu Zirui's innate musical talent has put great pressure on Zheng Boxu, and it has also become his driving force for continuous progress. Several young people who love music encourage each other on the road of youth, break through their limits, and find their own direction in life. After experiencing many difficulties and challenges, they finally ushered in the harvest of career and emotion.
