It was a cold autumn morning as Heeseung stood in the mayor's office, listening to orders about a new case. It was necessary to infiltrate the lab in the city center, as there might be valuable substances left there to create an anti-virus serum. With the spread of the zombie virus, everything changed in Heeseung's life. Instead of simply serving in the army for the required time, he stayed here, saving people who had not yet had time to become infected. Scientists were working on creating an anti-virus, and hunters were saving people from different parts of the country.

Heeseung clenched his jaw under the gaze of his Lieutenant, who was sitting next to the mayor. From the very first day Heeseung came to the base and saw her, he realized that he had big problems - he fell in love, and hard. He knew it was crazy, but what could he do about his feelings? He was just hiding them too well, and he was good at it. But it wasn't that she could notice anything - to her, he was just another subordinate.

Heeseung immersed himself in his job as a hunter, trying to forget the beautiful ice woman who had completely captured his heart. The mission briefing continued, but his thoughts kept drifting back to her serious expression and the way her hair fell slightly over her eyes when she was concentrating. This mission to the city center lab would be dangerous, even by their standards, but he found himself wondering if she would be accompanying the team or remaining at base.
