A vampire's last wish

I've died. Yet, here I stand. The why so unclear.
Immortality running, racing trough my veins.
And then, there she stood.
Perfectly alive. How could I not see her. Feel her. Taste her.
But how long could I stay?
The pain to know, that to stay with her forever would mean take away all she is.
The pain to know, that to live forever without her would be useless.
The fear to know, that what comes next, is the unknown.
What can I do? I can not, I must not abandon you.
She carries within her soul, my life.
What can I do?
Please death... Give back my mortality, and I shall be yours forever.
