Help with face mouse script

I’m trying to get my character’s Torso and Head to face the camera. So far the math in it isn’t that hard, but I faced a problem which I have no idea how to fix.

Problem

So, when I move my character, it’s like it offsets the mouse position or something. I have no idea why this happens.

Code 
local Player = game.Players.LocalPlayer
local Camera = workspace.CurrentCamera
local Mouse = Player:GetMouse()
local UIS = game:GetService("UserInputService")
local TweenSvc = game:GetService("TweenService")
local Character = Player.Character
local HRT = Character:WaitForChild("HumanoidRootPart")
local Head = Character:WaitForChild("Head")
local Torso = Character:WaitForChild("UpperTorso").Waist
local ToAnimate = Head["Neck"]
local OriginalCFrame = ToAnimate.C0
local CFrameValue = Instance.new("CFrameValue")
local Info = TweenInfo.new(.1, Enum.EasingStyle.Quint, Enum.EasingDirection.Out)
local Props = {}

local function UpdateCFrame()
	ToAnimate.C0 = CFrameValue.Value
	Torso.C0 = CFrameValue.Value
end

CFrameValue.Changed:Connect(function()
	UpdateCFrame()
end)


UIS.InputChanged:Connect(function(Input, GameProc)
	--if not GameProc then return end
	
	if Input.UserInputType == Enum.UserInputType.MouseMovement then
		if Camera.CameraSubject:IsDescendantOf(Character) or Camera.CameraSubject:IsDescendantOf(Player) then
			local Distance = (Mouse.Hit.Position - Head.CFrame.Position).Magnitude
			local DifferenceX = (Mouse.Hit.Y - Head.CFrame.Y)
			local DifferenceY = (Mouse.Hit.X - Head.CFrame.X)
			local AngleX = math.atan(DifferenceX / Distance)
			local AngleY = -(math.asin(DifferenceY / Distance))
			Props.Value = OriginalCFrame * CFrame.Angles(AngleX, AngleY, 0)
			local Tween = TweenSvc:Create(CFrameValue, Info, Props)
			Tween:Play()
		end
	end
end)

Thanks for reading ig

It might be in the details, as something is being swapped here, isn’t it?

Yeah you’re right. Something is being swapped here, I’m guessing it has something to do with the logic I used. However, I can’t figure it all out. I am aware of other methods, but they all have the same bug.

Does this have to do with the fact that the origin of the mouse and the head of the character are different?
