In Suzhou in 1926, a flash of light and shadow in the Lanting Villa triggered the fate of Shen Qingyuan, the daughter of the Shen family, and Gu Yanting, who had returned from studying abroad. Because of the restoration of ancient books and the mutual appreciation of each other, young feelings quietly grew in the mist and rain in the south of the Yangtze River. However, when Gu Yanting's identity as a "descendant of the Gu family" was exposed - he came to avenge his father, the old grudges between the Shen and Gu clans were suddenly revealed. The family's strong opposition was like a boulder, and the two fell into a quagmire of conflicts and struggles.
The war soon spread to Suzhou, and Gu Yanting was forced to join the army, while Shen Qingyuan was arranged to marry by his family. The oath Lan Ting made on the eve of their separation was shattered by a misunderstanding, leaving only pain and despair. Ten years later, on the streets of Chongqing, Shen Qingyuan, who had become a widow, ran into Gu Yanting, who was seriously injured. However, there was already a beautiful woman beside him. The reunion was only polite and distant, and the old grudges have not disappeared.
After the Liberation War, Shen Qingyuan returned to the abandoned Lanting. The red bean bracelet hidden by Gu Yanting in the corner finally revealed the truth of the misunderstanding. It's just that time is hard to return and the rest of my life is long. Only endless thoughts and sorrow and regret linger among the ruins of Lanting.
