Enraged by the brutal gang rape of his sister, the protagonist drowns in vengeance, targeting the daughters of her wealthy, powerful assailants. With calculated ruthlessness, he seduces and corrupts them, turning their innocence into pawns of his wrath. Each encounter pulses with raw hate and twisted passion, as he strips away their privilege with merciless dominance, forcing them to taste the pain their fathers inflicted upon his family. The cycle of revenge spirals deeper into darkness.
