these two lines are what I'm gonna call the "intro line".
play it once for intro.
play it again for the first part of verse
"Sayin 'I love you' is not the words I want to hear from you
It's not that I want you, not to say but if you only knew"
on "knew", instead of playing the last eigth note in the intro line, you play
  0- |  instead of    3- |
