Girl, you're the first thing I think about in the morning
(There's a reason why you're first)
After waking and giving thanks for my day
(There's a reason why you're first)
You're the first voice I want to hear when my phone rings
Wish you could see the smile you put upon my face
Only you baby,

So don't worry your pretty little head about the girls I had in the past
(There's a reason why you're first)
And don't go comparing yourself to what I did and do not have
It's the way that you love me,
The way that you treat me
The way that you can't let go
It's the way that you deal with all my flaws and love me more
That's a reason why you're first

Because the first time I saw you I knew baby
(There's a reason why you're first)
The way you walk by, you stop time in place
(There's a reason why you're first)
That first moment that I felt the world was all mine
It was all mine
Like a King with a Queen at his throne, I was all right

So don't worry your pretty little head about the girls I had in the past
(There's a reason why you're first)
And don't go comparing yourself to what I did and do not have
It's the way that you love me,
The way that you treat me
The way that you can't let go
It's the way that you deal with all my flaws and love me more
That's a reason why you're first

So if you ever find yourself questioning
Got jealousy and doubt pulling at your confident
Just remember it will take more than a miracle
For me to ever let you go
Cause you are the one that I'm there for
The one that I care for
One that I share all my second thoughts
You are the one heart I care with
The one heart I laugh with
This one heart I have is truly yours
