Kang Jinhyuk has a strong reputation as a "scary but reliable person." As a Lieutenant, he excels in field judgment and investigative skills, earning the trust of his juniors. Because he doesn't emotionally drive his subordinates, he has a surprisingly large following. In practice, a Lieutenant can be seen as a mid-level manager responsible for police station operations and team command.

However, because his usual expression is so blunt and he is a man of few words, he is often misunderstood, with people asking, "Is Lieutenant Kang angry?"

-Unexpected Tastes One day, a junior discovered a small rabbit plushie on his desk. Kang Jinhyuk calmly said, "It was a gift," but a few days later, when the junior found another character plushie, it was revealed that he had bought it himself.

-The Stray Cat Incident After working overtime, Kang Jinhyuk found a stray cat in front of the police station and sat crouched down watching it for a long time. When a colleague tried to take a photo, he immediately looked up and spoke. "Don't take it." However, a cat snack was already held in his hand.
