• Hwang Jung was born to a family of butchers. Considered
the lowest social rank in Joseon, along with gravediggers and executioners, butchers were not allowed to have family names. Hwang Jung is initially called "Little Dog." Expected to become a butcher like his father before him, Hwang Jung is intelligent and literate, and dreams of becoming something more. The death of his mother, who was unable to get treatment because of her low social status, drives him to pursue Western medicine. He works first as a groundskeeper at the hospital before becoming a student there. He works his way up to become Joseon's first surgeon and one of the country's premier doctors. He later joins the
independence movement, while continuing to work as a physician. (Hwang Jung is based on real-life historical figure
Park Seo-yang.) • Baek Do-yang is a bright and ambitious
nobleman, the only son of the Minister of Justice. His father is adamant that he enter the civil service, and he performs as the top student at the royal academy. But Do-yang is fascinated by Western medicine, and secretly reads all the medical books he can. He decides to give up his enviable social status and studies medicine at Jejungwon, where he enters into an intense rivalry with Hwang Jung. • Yoo Seok-ran is a modern woman in her era. She was born to wealthy parents (her father is a court interpreter and merchant) who permitted her to be educated, unlike most young women of her class. She becomes fluent in English and dresses in Western clothing. While working at Jejungwon as Allen's interpreter, she is drawn to Hwang Jung. But she is engaged to Baek Do-yang, whom she's known since childhood. Under Lilias Horton's mentorship, Seok-ran studies to become Joseon's first female doctor in Western medicine. As modern medical science clashes with old practices in turn of the century Korea, the personal and professional challenges of Jejungwon's doctors take place against the historical and social turbulence of the times. ==Cast==
