Summary
Tom waits in silence as another calculating gaze takes hold of the elderly alpha’s features, it turns solemn in the end, indicating that he’s come to a conclusion.
“You live in muggle London don’t you?”
Tom didn’t have a good feeling about this, but even so, he gives him a reluctant nod of assent. The solemn look on Arcturus’ face turns sharp for a second before he bares his teeth in the mockery of an amicable smile.
“That’s settled then”
“…Sir?”
And that’s how Tom Marvolo Gaunt ended up babysitting an absolute stranger in his own home.
Or,
They were never meant to fit. Forced to share space, two souls collide in a tangle of power, instinct, and something dangerously close to love.

Summary
On the eve of Harry's sixteenth birthday, he finds himself, as so many do, waiting up for a sign from his soulmate – for the words streaked across his wrist that will, potentially, determine his future. He never expected, never dreamed that it would all go so wrong.
Of course, he never expected either to wake the next morning to find his soulmate tucked up next to him, fresh from a whirlwind trip forward through time, either.
Well, no one ever said Harry's life would be easy. Still, the heart wants what it wants – and more than anything, now, all Harry wants is to keep his soulmate by his side. It's unfortunate, then, that Voldemort wants his own soulmate, too.

Summary
Harry’s interest in Tom is purely professional. He’d make an interesting character in one of his future books, that’s all, and Tom certainly doesn’t seem to feel anything for Harry outside of mild annoyance.
And if neither have met their soulmates by now, what are the odds that they'd find their match at Borgin & Burkes, of all places?

Summary
Still drowning his sorrows years after cutting ties to the magical world, Harry Potter meets a handsome stranger at his regular bar who asks one too many prying questions about the past. Talks of vengeance and violence always hit a tad too close to home as the stranger invades every aspect of his life with shocking speed.
-
The stranger has arranged himself comfortably on the faux-leather sofa, hands draped across the backrest and one foot placed on the smudged glass coffee table in front of them as if he owns the place. The lights above highlight meticulously groomed black hair, a few slick strands falling effortlessly in place.Oh no. Harry is far more attracted than he should be to someone with a past as violent as his own.
It takes a few more sips before Harry finds his tongue again. ‘’Sshhooo…’’ he slurs, then coughs. ‘’So what’s your plan then? Hangin’ out here till this guy arrives and stab ‘im?’’
‘’That was one option,’’ the stranger replies, playing around with an unlit cigarette. Harry follows the movement with rapture. ‘’But I’ve been told multiple times that there are things far worse than simply ending it. I suppose I’ll take him up on those words.’’
