Talk to me

Spill the secrets you've been keeping

Life cuts deep

Let me help pick up the pieces

You're not alone, I'm by your side

Don't you know, don't you know

I'll walk through fire with you

I'll walk through fire

No matter what, I'll make it right

Don't you know, don't you know

I'll walk through fire with you

I'll walk through fire

I'm not an angel, I'm not a saint

I've been a closed book full of mistakes

But when you're broken, when you're in pain

Oooh, ooh

I'll walk through fire with you

I'll walk through fire

I'll walk through fire with you

I'll walk through fire

You know I

Don't pretend to be a savior

But let me in, yeah

I promise nobody can break us

You're not alone, I'm by your side

Don't you know, don't you know

I'll walk through fire with you

I'll walk through fire

No matter what, I'll make it right

Don't you know, don't you know

I'll walk through fire with you

I'll walk through fire

I'm not an angel, I'm not a saint

I've been a closed book full of mistakes

But when you're broken, when you're in pain

Oooh, ooh

I'll walk through fire with you

I'll walk through fire with you

I'll walk through fire

I'll walk through fire with you

I'll walk through fire with you

You're not alone, I'm by your side

Don't you know, don't you know

I'll walk through fire with you

I'll walk through fire

I'm not an angel, I'm not a saint

I've been a closed book full of mistakes

But when you're broken, when you're in pain

Oooh, ooh

I'll walk through fire with you

I'll walk through fire with you

I'll walk through fire

I'll walk through fire with you

I'll walk through fire with you
