1931, Shiliupu Pier.
As soon as Shen Shuying, who had returned from studying abroad, set foot on her homeland, she was pressed against her forehead by the muzzle of a cold gun.
The man holding the gun was Lu Huaijin, the cold-blooded marshal who controlled Shanghai.
She exchanged secret messages for a transactional marriage and stepped into the crisis-ridden Lu Mansion. He used the muzzle of his gun to protect her, and she used her paintbrush to pry open his past.
The flames of war ignited the mountains and rivers. They made a lifelong commitment in the rain of broken glass in Nanjing, and then let go of each other's hands in the artillery fire of Marco Polo Bridge.
This separation lasted eight full years.
She spoke for China with her paintbrush in Paris, while he defended his country behind enemy lines using the code name "Lao Huai".
After her victory, her painting exhibition caused a sensation in Chongqing. On the guestbook, someone left a line:
"The person in the painting is still there, but his beauty has changed. - Lao Huai"
She chased her out, and the streets were filled with people who had returned, but he was not alone.
She has been painting the lonely city in mist and rain all her life. There are people in the painting who can't wait, and the rest of their lives that can't wait.
