Zhou Jianing was admitted to a key university, but her parents kept the money for her younger brother and forced her to get married. Her grandfather leaned on a cane and took her all around the village to borrow tuition fees, and her uncle's family took out their son's apprenticeship money to let her walk out of the mountain ravine. Twelve years later, she returned to the village with an agricultural product procurement project, but for three days she did not visit the benefactor's home, and was scolded as "ungrateful and devoid of civic virtue." At the villagers' assembly, she opened her grandfather's old ledger, paid off her debts, and revealed the truth that her parents had the money back then but refused to support her. Facing her younger brother reaching out his hand for a position, she insisted that everything be done according to the rules. The people who had helped her in the past got new opportunities, and those who had spoken sarcastic words could also supply goods based on ability. But the grandfather she wanted most to repay was already gone.
