Mo Fan (played by Ren Zhong) and Jian Dan (played by Gao Lu) are a typical couple born in the 1980s. They raise their lovely little daughter Mo Qi together and live a happy life. At first, the two who had just entered the age of 30 did not feel the burden of having an old and a young child. However, when Jian Dan's mother Liu Yunying was diagnosed with cancer, the spring of Jian Dan's family was over. Jian Dan tried his best and paid a huge price just to save his mother's life. Unfortunately, Liu Yunying eventually fell under the clutches of the disease. After that, Mo Fan's father had another heart attack, which made the situation of Jian Dan's family worse. To make matters worse, Jian Dan's daughter was diagnosed with autism. At the same time, her arbitrary way of doing things caused a rift in her relationship with Mo Fan.
