27-Year-old lawyers Wen Xi and Yan Zhao accidentally discovered that they were miscarried at birth and were forced to exchange families and fiancés. Wen Xi married Shang Chen, the old-fashioned but protective CEO of Shang. This started as a suitable flash marriage and gradually heated up amid repeated family conflicts, misunderstandings and protections. In the pain of her native family, Wen Xi gained Shang Chen's thoughtfulness and the love of her biological parents. The two of them slowly opened their hearts and became affectionate from strangers to each other. Faced with Yan Zhao's jealousy, adoptive mother's difficulties and other twists and turns, they worked together to resolve it, and finally moved from contract marriage to true love. Wen Xi finally healed the past in warmth and embraced happiness.
