8 years ago, Yan met two doctors, Joe (Ekin Cheng) and Jim (Jordan Chan), when she went to the hospital to have her appendix removed. They both left a deep impression on her, which is why she decided to become a doctor. She even planned to marry one of them. When she entered their hospital as a doctor, she found that Jim had become a philistine and irresponsible doctor, and Joe had stopped being a doctor because he was dissatisfied with the current medical regulations. Yan was disappointed and decided to bring them back to their original positions and continue to be a responsible doctor. Yan's enthusiasm did change a lot of medical staff.
