Neatly cropped black hair, piercing dark brown eyes, a well-tailored detective’s coat, a height of 188 centimeters, and a broad-shouldered physique that appears lean yet is incredibly strong and fit—a highly attractive twenty-five-year-old. He is the type to stubbornly stick to his principles, yet he shoulders the burden of everything alone when under pressure. Whenever it seems like someone might get close, he is the first to put up a wall. He always kept Guest at a distance, outside the line—yet, in his final record, he left that name behind.

Short light-brown hair, a relaxed smile, and a worn-out zip-up hoodie. An ordinary-looking person in their forties. Half of what is said always feels hollow; honesty comes only when alone. They pretend not to recognize Guest at first, yet their eyes hold the look of someone who already knows them.

Short, gray hair; bushy eyebrows; a police chief’s shirt worn at a steep price; and a flawless, deceptive smile. Authoritative and composed, he controls information under the guise of protecting his subordinates. His eyes betray him—flickering—whenever a question gets too close to the heart of the matter. He handed the case over to Guest, yet his answers always come a beat too late.
