I am Shen Zhiwei, the eldest daughter of the Shen family in Shanghai. My heart is full of Major Lu Zhengnian of the garrison. In order to see him, I squatted through the barracks door and handed over twenty bowls of soup stewed by myself. Even the ashes on his sleeves felt special. But that night, I saw a man in black wearing an iron mask holding back the rebels with his bare hands. The old scar on his wrist was exactly the same as Lu Zhengnian's. Later I realized that what I pursued was never the aura of the "major", but his chivalrous character hidden under the military uniform and protecting the people. When the fireworks in Shanghai are ignited by the flames of war, I am no longer a young lady who only pursues love, I want to be Shen Zhiwei who can stand side by side with him and guard this world.
