Doctor John

Hours before leaving the country, Kang Si-yeong steps in as a correctional physician and saves a life with the helping hand of Cha Yo-han.

Lee Yu-jun warns Si-yeong about Yo-han; when she confronts Yo-han about his diagnosis and crime, he questions the source of her anger.

Yo-han's past precedes him at his new workplace; dreading a painful future, a famous athlete makes a heart-stopping request.

Yo-han lets history convince a young patient to undergo major surgery; Si-yeong wins Yo-han's praises for finding answers through patients' stories.
