In Forest and Descendants of the Sun, both leads are officers (in Forest, the male lead is partly a rescue officer) and doctors (the female lead is a doctor). There is little to no love triangle with the leads, and both female leads are kind-hearted doctors. The story also occurs in a remote place. While DOTS focused more on Argus and the children, Forest focuses on the elderly who are poisoned by the village's running water. In both stories, the female lead has been kidnapped to threaten the male lead.
