Spring Sleep, Unaware of Dawn

The female lead, Su Jie, is a medical laboratory doctor in the infectious disease department of the Center for Disease Control and Prevention in the fictional city of Chujiang. After one of her patients disappeared without a word upon learning the test results, the center director threatened Su Jie, ordering her to find the missing minor. While searching for Tian Zhenzhen, the female lead got into an argument with Tian's mother, Shi Zhenxiang. Li Muqing, a friend of the male lead, stepped in to help. Recognizing Su Jie's potential usefulness, Li Muqing began approaching her for various reasons. Tian Zhenzhen was the mistress of Shen Bairuo, chairman of Wensheng Group, and Li Muqing wanted to use her as a stepping stone to help the male lead bring Shen Bairuo down.
