I had a first love
the sun rose and set with him
he was my everything
and had my everything
and then one day I found
that I didn't love my first love anymore

First love implies there is a second
that's you, for me
my second, my last

My worst fear is that one day
you'll find out what I found out back then
and then I'll be the one left haunted by you
left behind as your first
