Why does the Angle reset?

local run = game:GetService("RunService").RenderStepped


local keyheldq = false
local keyhelde = false

function onKeyPressQ(inputObject, gameProcessed)
	if inputObject.KeyCode == Enum.KeyCode.Q then
		keyheldq = true
		while keyheldq do
			
		torsorot = 0
		local rot = 0
		
		while torsorot < 100 do
			
			torso.CFrame = CFrame.new(torso.Position) * CFrame.Angles(0, rot, 0)
			
			rot = rot + .01
			
			print(rot)
			run:wait()
		end
				
			
			wait()
		end
	end
end


function onKeyReleaseQ(inputObject, gameProcessed)
	if inputObject.KeyCode == Enum.KeyCode.Q then
	print("Stopped holding the Q!")
	torsorot = 100
	torso.CFrame = CFrame.new(torso.Position)
		keyheldq = false
	end
end

game:GetService("UserInputService").InputBegan:connect(onKeyPressQ)
game:GetService("UserInputService").InputEnded:connect(onKeyReleaseQ)

When the key Q is released, it doesn't stay at the Angle, it resets the angle to 0 again, and it doesn't stay,

I'm trying to make a character customization menu.

This is for character rotation as you might noticed.
