For four years of college, Jiang Sui only received 300 yuan transferred by her father every month, surviving each day on steamed buns with salted vegetables. Until a phone call from her mother pierced through the truth: her biological mother, Jiang Lan, gave her father He Zhiqiang 6000 yuan of living expenses every month, totaling 2.88 million over four years, which was completely withheld by her father, fattening her stepmother Luo Yan and stepsister He Yutong, who were spending this money swaggering around school. Jiang Sui calmly fought back, showing down publicly and exposing the evidence; Jiang Lan hired a lawyer to recover it by law, sealing properties and deducting payments monthly. Her stepsister's supplementary card failed, she suffered campus social death, and she worked to repay her debts.
