Hwang said, "I thought about two things when making this film. First, I wanted to let the world know about this horrific incident. Secondly, I wanted to expose the structural problems of society as revealed during the process of how the case was buried. The issues portrayed in the movie -- sexual violence against children, corrupt ties between police and influential families, negligence of duty by civil servants -- is not fictitious, but can be seen regularly on the daily news."
