Shingo grew up in a violent household. Though he knew his father Masahiro constantly abused his mother Akane, years of childhood threats had numbed him to the fear. One night, when Masahiro returned home drunk, Akane's desperate cries of "Stop!" echoed through the house. Shingo rushed to her aid, only to find Akane clutched in his father's arms, moaning helplessly. "Mom... why are you doing this...?" he screamed inwardly, as deep conflict and uncontrollable desire surged within him. Unable to resist any longer, he approached Akane and reached out his hand.
