First kiss turns into panic
One touch from you, I'm frantic
I'm terrified that I might fall
Past love did me some damage
Past boy, way too volcanic
So hard to let down all my walls

Rules, I'm breakin' my rules
I'll lose 'em for you

So here's a little piece of my heart
It's not a lot, but it's a start
I'm sorry if I make it hard
Even when I'm in your arms
So here's a little piece of my heart
I'm scared of lettin' down my guard
I'm scared to give it all at once
But I can give it part by part
So here's a little piece of my heart

So free, so energetic
Lightning strike down from heaven
You got me fallin' in the dark

Rules, I'm breakin' my rules
I'll lose 'em for you

So here's a little piece of my heart
It's not a lot, but it's a start
I'm sorry if I make it hard
Even when I'm in your arms
So here's a little piece of my heart
I'm scared of lettin' down my guard
I'm scared to give it all at once
But I can give it part by part
So here's a little piece of my heart

I'm fightin' back feelings
For a million reasons
But, little by little, I'm healin'
I'm fightin' back feelings
For a million reasons
But, little by little, you heal me

So here's a little piece of my heart
It's not a lot, but it's a start
I'm sorry if I make it hard
Even when I'm in your arms
So here's a little piece of my heart
I'm scared of lettin' down my guard
I'm scared to give it all at once
But I can give it part by part
So here's a little piece of my heart
Here's a little piece of my heart
Here's a little piece of my heart
