To raise money for her mother's medical expenses, Lin Xingwan, a graduate in urban planning, starts livestreaming from her rented apartment. With her sincerity and expertise, she earns the support and protection of viewers such as Wan Feng, Mo Li, and Zhui Feng. She also encounters a mysterious viewer, "Xingchen," who finds comfort in her voice. Facing online harassment, plagiarism accusations, and controversies surrounding a competition, she learns to be brave with the support of those around her and gradually grows closer to Xingchen, Fu Beichen. From a starry-sky wall to a book titled Waiting for You, and finally to the renovation of an old steel mill that holds memories of the previous generation, she turns the affection she receives into a light that illuminates others, building a life in which her career, love, and family enrich one another.
