Due to the economic downturn, Kana's husband lost his job, leaving her to live with her husband and their only son, Takeshi. Her husband, devastated by the loss, drowned his sorrows in alcohol, drinking from morning until night. To support the family, Kana began taking in piecework from home. However, she was sexually harassed by the contractor, Sagawa, pushing her to the brink mentally. Enduring the abuse for her family's sake, she worked tirelessly, sacrificing her body to meet heavy orders. One day, Sagawa brutally raped her for falling behind on work—only for her son Takeshi to witness the entire scene. Her efforts to protect her family's happiness ended in the worst possible way.
