There Cannot Be A Close Second

You've got an extra special heart and a perfect light that shines through.
But it seems like the hardest part is shining back at you.
So forgive me if I don't know what to do when you look at me.
There can be no hesitation; there cannot be a close second to you.
I've got a perfectly normal heart, bruised and broken from within.
At times I don't know how to start to let you in here.
