The story, without the spoilers.
Captain Yoo Si-jin is a special forces officer who believes in protecting people first and asking questions later. Doctor Kang Mo-yeon believes in saving lives with skill, rules and a clear conscience. They meet, they clash, and they fall for each other — then life keeps placing them on opposite sides of the same hard choices. When Si-jin is sent to the fictional war-torn country of Urk, Mo-yeon follows as part of a medical team, and their romance has to survive earthquakes, epidemics, armed conflict and the simple fact that his job can ask him to take a life while hers asks her to save one. Descendants of the Sun is big, glossy and openly romantic, with sweeping scenery, a famous soundtrack and two leads whose chemistry carried the drama across Asia. The medical and military crises are dramatic rather than realistic, but the central question lands: can two good people with different codes love each other without giving up who they are?
A little curiosity. A new favourite.
