In the misty rain in the south of the Yangtze River, they first met and fell in love by the Qingliu River. During the years when they were young together, Shen Yanci and Su Qingyan had already engraved each other in their hearts.
Su Qingyan, the legitimate daughter of the Su family, is gentle and pure. She lives in a deep house and does not care about worldly affairs. She only wants to live a stable life;
Shen Yanci looks elegant and laid-back, but in fact he has an extraordinary background. He secretly holds the power and plans with patience every step of the way.
The two fell in love with each other, and with the tacit approval of their elders, they could have stayed together peacefully and spent their days together.
But the world is getting colder, and the undercurrent of troubled times is sweeping across the south of the Yangtze River. The powerful invasion of Shanghai's wealthy families is approaching step by step. The cousin who lives under the fence is jealous, and secretly colludes with foreign enemies to plot everywhere.
The peaceful life is suddenly shattered, the home and country are in turmoil, and parting is imminent.
In order to protect his beloved Zhou Quan, Shen Yanci reluctantly left and headed for the wind and rain ahead.
A city full of mist, a promise, and a long wait.
Even though the world is unpredictable, wars are everywhere, and we are separated by thousands of rivers and mountains, our original intention has never changed.
When the dust settles and the troubled times come to an end, he will definitely return from all the mountains and rivers, fulfill his youthful promise, and stay with her for the rest of his life, year after year.
