... or perhaps Voldarry.
Well, this is a "bonding fic" with a little difference.
Dumbledore tells Harry, in the King's Cross chapter of Deathly Hallows that Harry and Voldemort are bound together by a two-fold connection (soul and blood), and that Voldemort has wrapped their "destinies together more securely than ever two wizards were joined in history."
Since Voldemort is supposed to be brilliant, he realises that Harry and he are very closely connected after he has attempted to possess Harry in the Ministry. He is also along to hear the full extend of the Prophecy. So he hears the bit about "neither can live while the other survives" and it gives him an idea.
He no longer wants to kill Harry. Why should he? Harry is one of his Horcruxes! No, now Voldemort wants Harry as his consort. And he goes off to do what Voldemort does best: seduce people. Seduce Harry.
And Harry, for some reason he himself knows best, goes along.
