Shen Qingyan has been the most well-behaved lady in the capital for fifteen years.
The smile should be just right, the words should be watertight, and even the steps should be measured and measured. She is the most accomplished eldest daughter of the Shen family, and the most impeccable "model" in the circle of noble ladies in the capital - dignified, gentle, and never wrong. She thought her life would be like this - being bound by rules, being tightly bound by family status, being overwhelmed by the word "eldest daughter", and then marrying a child of an aristocratic family chosen by her parents, and spending the rest of her life treating each other as guests.
Until she met them.
