Obstetrician-gynecologist Lin Wantang has been secretly dating Shen Yan for three years, but he has never made their relationship public. When Su Wanqing returns to the country pregnant, Shen Yan accompanies her to a prenatal checkup, only to tell Lin Wantang in the examination room that he doesn't know her. Six weeks pregnant herself, Lin Wantang is repeatedly made to take a back seat until she finally moves out and ends their relationship. Su Wanqing then stages a fall, files complaints, and falsely accuses Lin Wantang of leaking her private information. Shen Yan eventually uncovers the truth and learns that he must stop making decisions on Lin Wantang's behalf. Lin Wantang transfers to Nancheng, publicly clarifies the situation through a livestream, and stands firm on her professional principles. Shen Yan returns to prenatal appointments, this time openly participating as the child's father. After their baby is born, the two do not immediately get back together. Instead, they begin getting to know each other again, and Shen Yan is willing to wait for her.
