아빠, 밀린 분유값 주세요!

A three-year-old boy shows up at a mansion on a rainy night, clutching a worn teddy bear and a hospital bill—demanding his billionaire father pay three years of child support. The family tries to bury the truth, but the boy carries his late mother's secret: a recording pen sewn inside the teddy. Piece by piece, the lies unravel—deleted texts, forged transfers, and the vicious scheme that drove his mother away. The real villain? The elegant grandmother, who deemed a commoner's blood unworthy. Justice arrives. A father finds his son. A mother's final wish comes true.
