An immortal's wish (a poem using numbers)

I have owned twenty acres
and I have hired hundreds of workers.
I have lived in five different manors
And I have cared for seven generations.

I have won hundreds of wars,
And killed thousands of conquerors.
I have enjoyed life in every decades
And tasted all kinds of valor.

I have done seven cardinal sins
And payed it with seven virtues.
I have received seven youthful years
And learned to overcome my fears

But all these equates to zero.
Still craves for something unattainable.
Like to have a heart more than two.
To love her with no due.
