[Verse 1 - Haydn]
I never wanted us to wear thin
I didn't want to be the cause of this harm
But I could never break my own skin
And let the blood spill into open arms

[Pre-Chorus - Both Haydn & Millie]
You're a pain in my chest
The softest thorn in my side
The perfect sort of heartache
But I don't want to watch my severed heart break

[Chorus - Haydn, Both]
And I don't want to watch my severed, my severed heart break
'Cause I'm only going to hurt you
And I don't want to watch my severed, my severed heart break
'Cause I'm only going to hurt you

[Post-Chorus 1 - Both]
I'm going, I'm going
I'm going, I'm going to hurt you
I'm going, I'm going to hurt you

[Verse 2 - Haydn]
You have a certain kind of sadness
When you know that, you will end up in tears
But it's the way that this will happen
This is the way that I will break you, my dear

[Refrain - Both]
You're a pain in my chest
The softest thorn in my side
The perfect sort of heartache
But I don't want to watch my severed heart break

[Bridge - Haydn]
I never want to be alone again
I didn't want us to untie in this way
I never want to be alone again
So I hope you still believe it when I say, that
[Pre-Chorus - Both]
You're a pain in my chest
The softest thorn in my side
The perfect sort of heartache
But I don't want to watch my severed heart break

[Chorus - Haydn, Both]
And I don't want to watch my severed, my severed heart break
'Cause I'm only going to hurt you
And I don't want to watch my severed, my severed heart break
'Cause I'm only going to hurt you
And I don't want to watch my severed, my severed heart break
'Cause I'm only going to hurt you
And I don't want to watch my severed, my severed heart break
'Cause I'm only going to hurt you

[Post-Chorus 2 - Both]
I'm going, I'm going
I'm going to hurt you
I'm going, I'm going
I'm going to hurt you
I'm going, I'm going
I'm going to hurt you
I'm going, I'm going
I'm going to hurt you
[Outro - Both]
Going, go-
Going, going to hurt you
Going to hurt you
Going to hurt you
