Ten years ago, her husband, Hu Jianguo, disappeared while racing cars. Despite having the intellectual capacity of a twelve-year-old, Xi'er worked tirelessly to raise her younger brother-in-law, Hu Jiye, and helped him become the only university graduate in Hu Family Village. Unexpectedly, Hu Jiye grew to despise Xi'er for being mentally disabled and embarrassing him. Together with his girlfriend, Wu Lulu, he secretly plotted to seize Xi'er's property and drove her out of her home. Just then, Hu Jianguo, who had been missing for many years, finally returned. Concealing his identity, he uncovered the hardships and injustices Xi'er had endured over the years and kicked the ungrateful Hu Jiye out of the house. Two devoted companions, bound by loyalty and mutual understanding, stand by each other and walk hand in hand toward a hopeful future.
