Is there any backstory to Angel's Wings?

The story behind the song:

Once upon a time, there was an angel who promised a little girl that he would love her when she grew up. To fulfill this promise, the angel came down to earth, but he couldn't find the girl until he met a prostitute. The angel promised the prostitute that he would be willing to trade a feather from his wing every day in exchange for the little girl to write him a letter. The angel used the last feather from the prostitute, in exchange for one last letter, and walked away.

A few days later, people were talking about a dead angel who had been found in the woods with no more feathers on his wings. The whore had also heard of this, and she said with disdain at this, "Hmph! An angel! How dare they believe such a ridiculous thing! It's ridiculous! When I was a child, there was an angel who said he would love me!"

Lyrics:

Where will the fallen leaves go with the wind

Leaving only the sky to be beautiful

The voice that once danced

Like the wings of angels

Scratched through my happy past

Love has come to the place

Where the scent of yesterday is still there

The familiar warmth

This is the first time that I've heard of this song.

Like an angel's wings

Crossing my boundless heart

Believing that you're still here

Never gone

My love is like an angel's guardian of you

If life goes on until this place

There's no more of me

I'll find an angel to love you in my place

There's a place where love once was

A place where love has come and gone

The fragrance of yesterday still lingers

The familiar warmth

Like angel's wings

Crossing my boundless heart

Believing that you're still here

Never gone

My love is like an angel's guardian

If life goes on until here

There's no more me

I'll find an angel to love you for me. I'll find an angel to love you for me

Believe you're still here

Never gone

My love is like an angel guarding you

If life goes on till here

If life goes on till here

If life goes on till here

I'll find an angel to love you for me

I'll find an angel to love you for me?
