1946, Chongqing. Shen Qingning's world collapsed the moment her best friend Lin Shuyao jumped into the Jialing River. The person who taught her to read poetry, play the piano, and told her to "be a thoughtful woman" used a river of water to teach her the last thing - to survive.
She took over the book of poems with the code and became an intelligence agent codenamed "Nightingale".
Her brother Shen Huaijin appears to be a major adjutant of the Second Military Command, but in fact he is "Mo Yan", an underground party member who has been lurking for many years. They have lived under the same roof for more than ten years, and they are each other's only relatives in the world. He didn't know when she took over Shuyao's mission, and she didn't know how many years he had been walking on the edge of a knife.
They never spoke of love. Can't say, dare not say, don't need to say.
He watched her walk on the road of no return, and used a fake interrogation to teach her how to survive; she kept the secrets that could not be seen for him, and listened to his returning footsteps every night. He watched her dancing with others from the edge of the dance floor, his knuckles clenched until they turned white; the moment he took off the silk scarf on her wrist, she heard his heart beating so fast that it seemed to be running.
From Chongqing to Nanjing, from Nanjing to Shanghai. The espionage chess game is thrilling at every step, and Jiang Fang's plan is at stake. The Secrecy Bureau's suspicions are getting closer and closer, and Zhou Mingyuan's temptations are getting deeper and deeper.
The night before leaving, he drank a lot and finally kissed her - not on her forehead, not between her brows, but on her lips. Lips that smell of wine, hot and trembling.
