I'm in love with an angel, heaven forbid

Made me a believer with the touch of her skin

I'd go to hell and back with you

Stay lost in what we found

Worlds apart we were the same

Until we hit the ground

Maybe I'm crazy, maybe I'm weak

Maybe I'm blinded by what I see

You wanted a soldier but it wasn't me

'Cause I could never set you free

So fly on your own

It's time I let you go, go

Go!

I'm in love with an angel who's afraid of the light

Her halo is broken but there's fight in her eyes

Walls are built to keep us safe

Until they're crashing down

Worlds apart we were the same

Until you hit the ground

Maybe I'm crazy, maybe I'm weak

Maybe I'm blinded by what I see

You wanted a soldier but it wasn't me

'Cause I could never set you free

So fly on your own

It's time I let you go, go

Go!
