This song sounds like it's a message from Aerith to Cloud. I can actually see a vision of them together when she sings this.
It's sweet and kinda melancholic.

One Breath Away

Once upon a love song, when nothing could go wrong,
Was it your heart that I wrote my name upon?
It never really mattered, never had an answer for a love so strong,
So I'll stay in my way until, don't you be long.

One breath away from wherever you are,
One day I know I'll be back in your arms.
Forever remember we'll always be together, one breath away.

I wish that I could tell you the story of my heart,
And how I found the one that I was waitin for.
Don't you know then you go for time, we'll always be...

One breath away from wherever you are,
One day I know I'll be back in your arms.
Forever remember we'll always be together, one breath away.

I'm only one breath away, one breath away,
Forever, forever I'll be, forever, forever I'll be.
And if there's one thing I know, I'm one thing I can be sure of,
Oh baby, wherever you are, I'm there in your heart to stay.

One breath away, oh, one day I'll know,
One breath, one heart, one day forever, one breath, one heart, one day forever you are,
One breath, one heart, one day forever, one breath, one heart, one day forever, forever...
