Lin Wanwan breaks down in tears in a hospital stairwell over her grandfather’s efforts to ward off bad luck, and she meets Shen Yanzhi, a gentle male doctor. From a patient’s family member to a colleague, from exchanging feelings through sachets to working together in a clinic combining Chinese and Western medicine, they find love and healing in the hospital corridors where life and death intertwine. With a stethoscope and silver needles as their pens, they write their love story amid the scents of medicine and disinfectant, ultimately finding fulfillment in both family and career.
