I don't own twilight, the song is by Paramore: The Only Exception

It was a dark misty night at the Cullens house. Emmett and Jasper were at a football game, Carlisle and Esme were out on a walk, and Alice and Rosalie were shopping for all new designer fall fashions. Edward and Bella were Happy to be alone for a while, just enjoying eachother's company.

"Edward I wrote a song for you", Bella whispered.

"Really? I didn't know you wrote music."

"Only for you love, you are the only exception." With that Bella got up and brought out her father's old guitar, the one that he use to use to sing to her mother when they were still together.

In a sweet soft voice Bella began to sing:

When I was younger
I saw my daddy cry
And curse at the wind
He broke his own heart
And I watched
As he tried to reassemble it

That day was ingrained in Bella's head. She remembered how much that day had scared her, and how she never wanted there to even be a chance for that to happen to her. She was so terrified she put up walls around her heart so nothing could ever hurt her like that.

And my momma swore that
She would never let herself forget
And that was the day that I promised
I'd never sing of love
If it does not exist

But love did finally exist, she was skeptical in the beginning, but she knew it was really love. How could a person take away all your doubts and fears with just one gaze, and it not be love? How could a person make you feel like flying and shouting, and it not be love. How could a person light up your world and show you the stars when you never truly noticed how bright they were before, and it not be love?

But darling,
You, are, the only exception
You, are, the only exception
You, are, the only exception
You, are, the only exception

Edward was the only exception.

Maybe I know, somewhere
Deep in my soul
That love never lasts
And we've got to find other ways
To make it alone
Keep a straight face

And I've always lived like this
Keeping a comfortable, distance
And up until now

I had sworn to myself that I'm
Content with loneliness

She would never be lonely again! Even after those few terrible months, their love had survived and she'd never let him go again.

Because none of it was ever worth the risk

Well, You, are, the only exception
You, are, the only exception
You, are, the only exception
You, are, the only exception

I've got a tight grip on reality
But I can't
Let go of what's in front of me here
I know you're leaving
In the morning, when you wake up
Leave me with some kind of proof it's not a dream

Ohh-

You, are, the only exception
You, are, the only exception
You, are, the only exception
You, are, the only exception
You, are, the only exception
You, are, the only exception
You, are, the only exception
You, are, the only exception

And I'm on my way to believing
Oh, And I'm on my way to believing

Bella stopped playing and looked up into Edward's eyes. They were smoldering and, if he could, he would be crying. He ran up to her and picked her up swinging her around the room, never taking his eyes off of her.

"I hope that explains my feelings for you." Bella whispered.

Edward gently put Bella back on her feet, and looked dead serious. "perfectly", he said and touched his lips to hers.
