Combine corn, heavy cream, sugar, butter, salt, and pepper in a skillet over medium heat. Cook, stirring occasionally, until butter has melted, 3 to 5 minutes.
Meanwhile, whisk together milk and flour in a small bowl until smooth.
Add milk mixture to the skillet and continue to cook, stirring constantly, until sauce is thickened and corn is cooked through, about 4 minutes.
Remove from the heat, and stir in Parmesan cheese until melted. Serve hot.
