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.
