Gu Jinyan, director of the Cardiac Surgery Department of Jiangcheng Municipal Hospital, has superb medical skills and is cool and taciturn. He is the "white moonlight" in the hearts of patients. Jiang Wanqing, a Chinese teacher at the city's key experimental primary school, is an eccentric person with facial features and a life full of small blessings. The two met during a medical examination, and their daily interactions quietly began. His hands shook when he took her blood pressure, and she fidgeted while waiting for the report. When we visit the doctor again, we hold an umbrella together and WeChat becomes more and more popular. From the hospital to the campus, from work support to meeting parents, the feelings are warming up in the long flow. There are no bloody misunderstandings, just adults running in both directions. He is her affectionate doctor, and she is his daily heartbeat. Hidden in the ordinary fireworks is the gentlest love.
