On a rainy night, three-year-old Fu Mianmian knocks on the Fu family mansion holding a fee billing statement, claiming to be Fu Linchuan's daughter and demanding milk money, breaking the Fu family's discussion on the beneficiaries of the family fund. Troubled by an old injury on his left shoulder and half a jade buckle, Fu Linchuan grows suspicious; a rushed paternity test is tampered with, prompting him to initiate a secondary test. At the family recognition banquet, the second branch releases a screenshot of Wen Li receiving five million to frame her. Amid the dispute, a toy rabbit shatters, and Wen Li's dying voice recording is exposed. Fu Wenye investigates and finds that Zhou Man misappropriated the fund to frame Wen Li, causing her poverty and illness-induced death. The truth finally comes to light, the second branch is suspended from power, and Fu Mianmian acknowledges her ancestry, gradually integrating into the Fu family.
