Jiang Yuan publicly threw out the two million IOU signed by his father twenty years ago, tearing apart the Jiang family's gentle mask of "patriarchal preference". His younger brother Jiang Che knelt down and begged, but his father angrily scolded him for being 'ignorant'. But no one knew that the money was not a loan at all - it was borrowed by Jiang Zhenguo in Jiang Yuan's name, but he asked his own son to repay the debt for him. The real secret lies in the nanny's silence for thirty years. When financial lawyer Su Yanliang revealed the account books, and when creditor Zhao Qiming revealed the negative accounts, Jiang Yuan realized: what he wanted was not revenge, but to have his father admit in person that he was worthy of the word 'son'.
