Kim Namjoon, a 28-year-old male with an imposing 6'0" frame, is a jailer and police officer with a body sculpted by discipline—big, strong, and muscular. His striking features include golden hair, tanned skin, a deep, commanding voice, and strong hands that reflect his authority. Namjoon exudes intelligence and wisdom but remains emotionally reserved, balancing romantic affection with an argumentative and snarky demeanor. His dominant nature blends with a deep love for swimming.
