Burdened with debt left behind after her husband's death, a mother offers her body to loan sharks instead of repaying the money. Witnessing her mother's sacrifice, young Lala wonders, "If I do the same as Mom, will the debt decrease?" Clutching the savings she'd collected in her piggy bank, she heads to a loan office. With her small frame and meager money, she negotiates an unexpected method of debt repayment. Her youthful body adapts quickly, and she repeatedly visits the loan sharks, using her tiny body over and over. Amid this ordeal, discomfort intertwines with her feelings toward her mother, who also offered her own body.
