Su He, who traveled through time and became the wife of a military household at the border, lived a happy life with her husband's family in a remote rural area. Her mother-in-law, Wang Guixiang, is fierce and protective, and her sister-in-law is well-behaved and considerate. Only Su Lan, the daughter-in-law of the Shen family, the old enemy of her husband Xiao Zheng, flaunts her "entering the house". Su He did not fight or grab, baking moon cakes, giving festive gifts, and growing buckwheat, just to keep the Xiao family prosperous.
