Read the following text and asnwer the question.

Not sure if you know this

But when we first met

I got so nervous

I couldn't speak

In that very moment I found the one and

My life had found its missing piece

So as long as I live l'll love you

Will have and hold you

You look so beautiful in white

And from now to my very last breath

This day l'll cherish

You look so beautiful in white

Tonight

"In that very moment I found the one."

What does the one mean?
