Kim Sa Bu once held a top position as a surgeon at a major hospital, but he walked away from that life without warning. Now living in seclusion, he works at the small Doldam Hospital and calls himself Teacher Kim, the Romantic Doctor. His quiet world changes when two young surgeons arrive and disrupt the routine.
Kang Dong Ju became a doctor to rise above his difficult childhood and seeks recognition through high status patients. Yoon Seo Jung is skilled and passionate but struggles with guilt from a past mistake. Both encounter Teacher Kim at a moment when their careers and personal lives feel unstable.
Working under him, they face real emergencies, ethical dilemmas, and the emotional weight that comes with treating patients. Teacher Kim’s untraditional methods push Dong Ju and Seo Jung to confront their fears, grow as doctors, and understand what it means to pursue medicine with sincerity. As they navigate the challenges of Doldam Hospital, their time with Teacher Kim begins to reshape their goals, their values, and their relationships.
