• This ballad finds Luke singing about lost love and bad choices with the help of his bandmates. He expresses regret about the mistakes he made that forced his girl to walk away:
  
  Taking every breath away with all of the mistakes I made
  From all the letters that I saved
  This is everything I didn't say
  I wish I could've made you stay
  And I'm the only one to blame
  I know that it's a little too late
