In the capital city of Chu, Su Yao, the daughter of a general, has been fostered in the home of her second uncle Suning Zhou since she was a child. She has been harshly treated and bullied all year round. At her grandmother's funeral, Shen Yi, the second young lady of the Shen family with strong temperament, stepped forward to protect Su Yao. The two families were close friends. Su Yao's parents were stationed at the border and had no time to take care of their daughter, so they simply entrusted Su Yao to the Shen family to raise. During the ten years of living in the Shen Mansion, Shen Yi always guarded and accompanied Su Yao wholeheartedly, giving her candies, sewing dolls with his own hands, teaching her to play chess, and supporting her.
But the undercurrent has long been hidden: Su Yao's second uncle, Suningzhou, was resentful and colluded with the third prince to embezzle border military rations. After the incident, he was only imprisoned. He still secretly organized forces and waited for revenge, using Lin's mother and son to spy on and design a trap. The struggle for the throne in the court and border wars ensued. Shen Yi's brother Shen Chen went to the northwest to join the army and was injured. Suning Prefecture even deliberately framed Xiufang for having an affair with the third prince, and involved Su Yao and Shen Yi in the court turmoil. Two young girls who rely on each other and share the same mind must face the constraints of secular ethics on same-sex affection, while at the same time they must join forces to fight against Suningzhou's conspiracy, the power struggle in the court, and the turmoil of their home and country. In the turbulent capital, they must stick to their lifelong promise to each other and fight against the tribulations of the world with sincerity.
Intention: The world is full of hardships, but only by knowing each other and staying together can we withstand the cold years.
