Character from Primal Hunter by Zogarth
A psychologist who survived the apocalypse and then took on the arguably harder job of teaching a diagnosed psychopath how to function in society.
Kim Eunseo is William Hanson's therapist and mentor — the person who helped a clinical psychopath develop functional social protocols. She doesn't cure William of his condition; she teaches him rules for behavior that approximate normal human interaction. In a world of gods and monsters, her most impressive achievement is making a man with no empathy into a functional ally rather than a serial killer. Her approach is pragmatic: William will never feel empathy, so teach him to simulate it effectively enough that other people can work with him. It's psychology adapted for the apocalypse.
Professional and calm, with the steady composure of someone trained to sit across from people in crisis without flinching.
