I used to call you mystery
I wanted to play all the parts
Beware the one who calls for me
I'll only break your heart

The beginning's always beautiful
Like every brand new start
But in the end, when there's nothing left of you
I'll only break your heart

I want you with a harsh desire
I crave you in the night
But I'm here to warn you
You're not safe with me
I'll only break your heart
[ Lyrics from: http://www.lyricsfreak.com/h/holly+williams/ill+only+break+your+heart_10142407.html ]
It scares me like my deepest confession
It haunts me like their pain
While everyone's looking for someone to love
I'll only break your heart

I fade like every summer leaf
I drift like the mind of a child
I never was meant to stay in one place
I only broke their hearts

I used to call you mystery
I wanted to play all the parts
Beware the one who calls for me
I'll only break your heart
