This song is from Pansy's point of view to Draco. Draco cheated on Pansy with Astoria Greengrass. . . *GASP!* Haha I know, right? Anyways. . .
I got the idea from Evanescence's "Everybody's Fool".

NO MORE

I won't be lied to anymore.
I'm tired of this,
These lies, deception.

It all became clear as I looked in your eyes.
It was a make believe world.
A world that never was,
And never will be.

Now I know,
We never were,
We never will be.
You don't know how you betrayed me.

Somehow, you've got everybody fooled,
With one smile,
You turned my world upside down.

One glance,
One laugh.

Well, you're not real,
And I don't love you anymore!

There was once a time when I would have killed for you,
But you killed my heart,
And I will no longer write you a love song.
