She was born to play chess. As an experimental product with extraordinary abilities born in the laboratory, her mission was to defeat Country K and lead the alliance to victory in the war. Together with her name, Dawn, it is intended that she be the dawn of victory.
As a young and promising captain of K country, on the surface he is playing with the world, but in fact he is afraid of getting hurt, pretending to be cold-hearted and cold-blooded, and does not dare to easily reveal his soft and true feelings to others. However, this disguise was quietly removed in the day-to-day interaction with her who had sneaked into K country as a prisoner. He wanted to monopolize her quirkiness, her every smile, and her days and nights.
When the spy's mask is finally torn off, when mission and love are before her eyes, she will abandon everything on her shoulders and return to him. Can he forgive the ruthless deception and still protect her firmly? Or, if two people are pointing guns at each other, who can stop their trembling hands and pull the fatal trigger?
