Chen Chen, a nurse in the internal medicine department of Jiangcheng Central Hospital, was transferred to the psychiatric department by the hospital. In the psychiatric department, she faced various patients with psychological problems, including retired workers with obsessive-compulsive disorder, mothers with postpartum depression, elderly people with Alzheimer's disease, and engineers with anxiety disorders. From the initial incompatibility to professional and humane responses, she gradually grew up. At the same time, her relationship with anorectal surgeon Zhao Kai slowly heated up. In short, this is a "psychological popular science emotional drama" with social warmth.
