New Doctor X photos released on September 29 show Kim Ji-won as Gye Su-jeong in surgery, in a white coat and away from work. The images put the surgeon’s clinical focus beside her more ordinary life outside the operating room.

One photo shows Su-jeong masked and working in blue scrubs. Another presents her in a white coat, while a third shows her in everyday clothes. These are advance character images, not a recap of an aired episode.
