Twenty years ago, during the national college entrance examination, rural young man Su Jingchen earned admission to Qingbei University. However, his wife, Shen Xue, secretly switched his acceptance letter with the one belonging to her true love, Lin Ze. As a result, Su Jingchen spent the next forty years living an ordinary, unremarkable life in the countryside. In the end, even his children looked down on him. In her final testament, his wife left all her property to Lin Ze and declared that she had never loved Su Jingchen. Reborn, Su Jingchen resolves to stop loving Shen Xue, reclaim his acceptance letter, and pursue his studies at Qingbei University. Only then does Shen Xue begin to realize that she may no longer be able to live without him.
