In a blink of an eye, Ding Yu (played by Wang Lei) and He Xuelin (played by Qin Hailu) have been married for eight years. Although they have raised their lovely little daughter Yuanyuan together, the existence of this crystal of love has not been able to prevent the cracks in the relationship between the couple. In the end, their marriage is on the verge of collapse. Yuanyuan accidentally learned that her parents were preparing to divorce, and she chose to run away from home while her grandmother was not paying attention. Yuanyuan's disappearance brought a huge blow to the family. Ding Yu and He Xuelin had to temporarily put aside their grievances and join hands to find Yuanyuan's whereabouts. In the process, their already precarious relationship suffered a more severe test, but the difficulties that followed made them start to think about the meaning of marriage and life.
