The lonely and bitter orphan Lu Nian and his seriously ill grandfather depended on each other for survival. On the verge of starving to death, they were fortunately rescued by the Sun family couple of the meat cake shop. The Sun family spared no effort, exhausting their savings and even selling their dowry, gritting their teeth to support Lu Nian in his studies so he could succeed. But the good days shattered in an instant. The Sun family's biological son, Sun Liang, gambled heavily and caused a huge disaster, running up a huge amount of high-interest debt, which forced the cake shop to be mortgaged, leaving the two elderly people forced to wander and work to make a living. The successful Lu Nian heard the news and rushed back home, facing the routine-loan forces head-on, and stepped in to save his benefactors. He reformed the lost Sun Liang, helped the Sun family reopen their meat cake shop, established a charity window to pass on kindness, and completed a two-way journey of repaying kindness and redemption.
