Si Peilin, the only son of the Si family, and Yao Mi, the daughter of the Yao family, are childhood sweethearts envied by everyone in the Shanghai Bund Concession.
When we were young, we met under a crabapple tree. When he finished his studies, he came to ask for her hand in marriage. He kept the crabapple sachet she had embroidered by hand close to her all year round. Her sincere affection was known to everyone in the city.
However, the situation is uncertain, and conflicts of interest among the aristocratic families are coming one after another. The Shen family was in great power and wanted to form a marriage alliance. Through the mediation of many parties, the heavy pressure was placed on Si Peilin's shoulders.
In order to protect the Yao family from being implicated in the turmoil, Si Peilin chose to bear all the entanglements alone, willing to act as a ruthless person.
Alienating herself in public and acquiescing to the marriage contract with the Shen family, a young joke crushed Yao Mi's ten years of infatuation.
The disheartened Yao Mi went to the southwest, cut off the attachments of the past, shed her delicate and ladylike shell, and settled down and grew up in a foreign land.
The city was full of criticism, and everyone said that Si Peilin was heartless and unrighteous. No one knew that he was hiding under the surface of indifference and planning step by step just to clear the way forward and protect her stability for the rest of her life.
Mountains and rivers pass by, and years pass by. When misunderstandings are uncovered layer by layer, through the war smoke of troubled times, can the two old friends covered with scars still regain the unfinished promise they made under the crabapple tree?
Concept: Love in troubled times is a two-way burden and a mutual fulfillment.
