Love at first and only sight?

The moment I walked through the door,  was the moment I caught his eye.
It was as though my breath had been knocked from my body, as though time had stopped.

It had been an ordinary day before then. I'd gone to uni, I'd had lunch and I was about to go home. But some inexplicable force pulled me across the road and into the shop.
And that was it, my whole life was changed for ever.

It was like my whole life had been building up to this moment. Every love, every heartbreak was preparing me for this moment where he and I would discover one another.
I could hear nothing, save the swift, heavy pounding of my heart. The world around me vanished, and all there was existing for this moment in time was this man and me.
I had never believed in love at first sight, until this moment. Every sinew in my body was screaming for his touch and I knew if I didn't hear his voice I would fade away to nothing.
"Hi" I attempted. Barley more than a whisper
"Hey" was his softly breathed reply
His voiced sucked me in, held me in its warm embrace. He smiled at me, and I knew that he was feeling this too.

This was our moment.



And, then, the moment was gone. The world returned.

We left. Each turning for a final glimpse of the other, before heading in opposite directions.

Who is he?
And why does my heart feel so empty?
All i see in my sleep is his smile. I see his face in every crowd. And I know, that he alone holds my heart.

Will I ever see him again?
