When I listened to this song, I thought of Twilight, too!
It really fits. Here are a few of the lyrics:
I found a way to let you in
But I never really had a doubt
Standing in the light of your halo
I got my angel now
It's like I've been awakened
Every rule I had you breakin'
It's the risk that I'm takin'
I ain't never gonna shut you out
Everywhere I'm looking now
I'm surrounded by your embrace
Baby I can see your halo
You know you're my saving grace
You're everything I need and more
It's written all over your face
Baby I can feel your halo
Pray it won't fade away
And then it goes...
Hit me like a ray of sun
Burning through my darkest night
You're the only one that I want
Think I'm addicted to your light
I swore I'd never fall again
But this don't even feel like falling
Gravity can't forget
To pull me to the ground again
It's such a musy Bella and Edward song! I can imagine both of them saying it to the other, though I do lean Edward to Bella.
