Xue Shanshan awakens on the brink of death from acute gastritis, only to find herself reborn at the critical moment after college graduation, just before she is due to donate blood to Fengteng. In her previous life, a “special arrangement” made her Feng Teng's “convenient little helper.” She lost herself, became a laughingstock, and grew distant from her family, ultimately ending up unsuccessful at work and in failing health. This time, she firmly refuses to donate blood and resolves to live for herself.
Through hard work, Xue Shanshan joins Xingtu Medical, a company specializing in home medical equipment, starting as a newcomer in the marketing department. Her attention to detail and resilience help her grow quickly. At work, she meets Lu Xingyan, a hematologist at the city's central hospital. As gentle as starlight, he is not only the company's medical consultant but also offers her thoughtful help as she coordinates community clinics and negotiates partnerships. When difficult clients give her a hard time and Feng Teng pressures her again, he stands firmly by her side.
As they become closer partners, affection gradually blossoms between them, and they face one challenge after another together. When a power outage puts Lu Xingyan's surgery in jeopardy, she rushes to gather evidence and clear his name after he is slandered. As she makes her mark in the workplace, he remains her strongest support. From sweet dates strolling through the park, to winning their parents' approval, to a moonlit proposal, Xue Shanshan not only earns a promotion to deputy marketing manager but also makes up for the regrets of her previous life and repairs her relationship with her family.
In the end, Xue Shanshan and Lu Xingyan hold a warm wedding in a chapel on the lawn. They have a daughter after marriage and build a happy life with thriving careers and a loving family. She no longer chases an unreachable “sun,” but instead stays by the “starlight” at her side. With the courage and determination she found in being reborn, she becomes the person she once dreamed of being.
