The brightest star in the night sky

"Star Entertainment" is China's top entertainment company. The bosses Chen Tianhao and Du Wanqing were once a loving couple, but now they are in a marital crisis because of their differences in the company's business philosophy. Yang Zhenzhen (played by Wu Qian), who loves music, works at "Star Entertainment" and becomes the assistant of popular singer Zheng Boxu (played by Huang Zitao). Zheng Boxu is an idol singer with an arrogant and unruly personality that is difficult to control. Yang Zhenzhen gradually got to know Zheng Boxu while getting along with him, and helped him correct his shortcomings, develop his talents, and eventually become a singer with real ability. Yang Zhenzhen himself has also transformed from a rookie in the workplace to a mature agent. Du Wanqing sets out to train a newcomer Yu Zirui (played by Niu Junfeng). Yu Zirui's innate musical talent puts tremendous pressure on Zheng Boxu, and it also becomes his motivation to keep making progress. Several young people who love music encourage each other on the road of youth, break through the limits, and find their own direction in life. After experiencing many difficulties and challenges, they finally experienced career and emotional gains.
