In an era when war was raging across the country, a group of childish teenagers put on military uniforms and rushed to the battlefield to defend their homes and country. Among them are the rebellious general's son Ling Yun, the silent and tenacious Orion boy Amu, the astute and courageous doctor's daughter Su Wan, and the passionate and impulsive scholar Zhao Yi.
When they first entered the military camp, they clashed with countless sparks due to their origins and temperaments, from arguments they didn't like each other, to silent exchanges of warmth at the guard post late at night; from fierce competition on the drill field, to sacrificing their lives to protect each other at the critical moment of life and death. In the smoke of gunfire, Ling Yun learned to restrain his sharp edges, Amu stepped out of loneliness, Su Wan shouldered the responsibility with his medical skills, and Zhao Yi recorded the sincerity of the young people with pen and ink.
The cruelty of the battlefield allowed them to transform quickly, and their friendship was tempered indestructible by gunfire. The love between Ling Yun and Su Wan quietly grew in the flames of war, and their loyalty to their home and country has always been the eternal light in their hearts. When the horn of victory sounded, the young people lost their youthfulness, and their eyes became more determined and calm. They finally understood that growth is not an increase in age, but in protection and responsibility, and they understood the weight of friendship, the preciousness of love, and the heavy meaning of loyalty.
