At the emergency department of a hospital in H City, nurse Mao Xiaohu, Mao Li, and the “Ice Block” doctor Han Yidong are constantly rubbing each other the wrong way at work, each harboring deep-seated prejudices against the other. In early 2020, during the fight against COVID-19, they defy their families’ objections and volunteer for the front lines one after another. Fighting the virus together forges a bond between them, which deepens into mutual admiration as they become lovers in white coats, standing side by side.
In early March 2020, as medical teams sent to Hubei begin withdrawing in stages, Mao Li is diagnosed with COVID-19. She goes from caregiver to patient, while Han Yidong goes from comrade-in-arms to her attending physician. As they bravely battle the illness, they develop a deeper understanding of and shared outlook on love, life, and their ideals.
In April 2020, the cherry blossoms on the streets of H City are more vivid and radiant than ever, as if saluting the heroes. Mao Li, recovered, walks toward Han Yidong among the fragrant blossoms. She accepts his rose, and they embrace sweetly. At last, the lovers are united.
