In exchange for a ticket to the Olympics, talented shooter Chen Ye and devil coach Lin Jing signed a prenuptial agreement. They agreed: once they get the gold medal, their marriage will end. In front of others, they are a loving couple, united to win glory for the country; behind the scenes, he is the most unruly player, and she is the cold-faced and selfless coach. Until the finals of the World Championships, he was under tremendous pressure. Before the last shot, he silently mouthed to her in the audience in the global live broadcast: "Don't be afraid." Later, he broke the world record, but hung the gold medal around her neck. "Coach," he kissed her in public, his voice slightly hoarse, "the bullet hit the bullseye. And I hit your heart. I apply for a permanent renewal of this contract."
