Lin Jun (played by Chen Shu) and Tang Pengfei (played by Huang Lei) are firm DINKs. Both of them are successful in their careers. What is more valuable is that they have been married for ten years and their relationship is still the same. However, the death of Tang's father (played by Wang Zhiqiang) broke their peaceful life. Tang's father left a will for Tang Pengfei to have a child, and the couple fell into a dilemma. After all kinds of life, the couple finally decided to have a child, but after several efforts, they failed. By chance, they met Qi Wulan, who was pregnant but abandoned, and the couple proposed to adopt Qi Wulan's child. In everyone's eager expectation, the child was born, but at this time the power of motherhood made Qi Wulan regret it. Tang and Lin were left with nothing, but they could do nothing. With several failed IVF operations, Tang Pengfei and Lin Jun's marriage also went through several tests. The two finally decided to give up, but when they followed Qi Wulan to the grassland to visit the child, Lin Jun found that his body had changed strangely.
