After me the deluge

Hello lover I can't do you harm.
Middle lover I did do you harm whenever I want to.
Oh no, the ladder collapsing.
The matter relaxing. The girl can't sing.

LLLLLLLu lover running backwards now
Lover it is now.

Then tomorrow crashes down
At a hundred miles an hour, and it's sour.
The goodbye the goodbye
The lover sighs.
