Hey, Sister

Hey, sister, don't leave me waiting here like that.
You know you've got to choose one of us one day.
I've done so much, don't you feel a single thing?
You walk the other way, you know you're gonna pay.

Something is wrong here but I just do not know.
I can't put my finger on it just yet.
You have been hurting and I could comfort you,
But I seem to be just part of your duet.

Why am I feeling this?
I could've been content.
But now that you are his,
I'll just be your man.

Unrequited love,
Paves the way to pain.
It's obviously a curse,
Reminds me of my shame.

Hey, sister, turn away for just a short while,
I know what I promised and I know what I have said.
My rebellion stops me from the painfulness of leaving once again.

Why am I feeling this?
I could've been content.
But now that you are his,
I'll just be your man.

Unrequited love,
Paves the way to pain.
It's obviously a curse,
Reminds me of my shame.

Maybe my chances are something like quite nil.
And I'm so sorry for everything that's done.
I ain't coming back to suffer for your sins,
Why don't we part ways and just call it a day.

Why am I feeling this?
I could've been content.
But now that you are his,
I'll just be your man.

Unrequited love,
Paves the way to pain.
It's obviously a curse,
Reminds me of my shame.
Reminds me of my shame.

Guys, Need Help!!

Ok, I need some ideas for a piece I'm working on. Its called Sephirot (you can wiki that, not to be confused with Final Fantasy) and I was wondering about a few things:

1. Should I set it in the real world or in a fantasy world?
2. Obviously I'd need ideas for names of people (I suck at creating names). I'd appreciate it if anyone would drop a few interesting ones.
