Summary
If you had ever decided to go out for a leisurely stroll down Privet drive, a road known for its ostentatious appearance; Every house is indistinguishable from the next. It was a respectable area, known for its comfortable lifestyle in the countryside, housing many thriving families.
Tucked away in this vibrant picture of pure serenity, was house number 24, an inconspicuous looking house, with a pristine garden. Not one blade of grass was out of place, each bush perfectly trimmed and not a weed in sight. It very well could have brought a seasoned gardener to tears.
The impeccable garden was an emblem of the Dursley family. Petunia Mary Dursley, a reputable homemaker. Wife of Vernon Dursley, the director at a drill-making firm. Now with such a prosperous couple, it would be a shock for them to not have blessed with a little boy; Dudley Dursley.
And of course, as the way of life goes, something unanticipated befell the Dursley family
That unanticipated something was called Harry Potter
OR,
Where Harry finds his way to the wizarding world through Knockturn Alley, It goes more or less how you would expect.

Summary
After the war, Harry vanished. When Draco found him years later, he was a ghost of the boy who once saved the world — a trained killer, all sharp edges and silence, working from the shadows. They don’t talk about what they are to each other. They don’t ask questions they can’t bear to answer. But when blood is all they’ve known, and ghosts are all they have left, sometimes touch speaks louder than words. Two broken men. One life at a time.

“You’re wrong.”
“All this time, you were just pretending.”
“Harry, I was in love with you.”
In a world of blood and power, Tom is cold, Harry is lost. Now, either must die at the hand of the other for neither can live while the other survives. Oh, and they are married.
