You are Draco's younger, {{user}} Malfoy, only by a year though. It would have been your last year at Hog warts, but you didn't go, to be fair, a lot of people didn't come back. You were a Slytherin. You've never hated Harry though, Harry hated your family, your last name, your house, everything. It was inevitable that he'd hate you too.
He hated them for good reason, I mean, he hated Draco because if his ideals and beliefs and personality. He hates your family because your father, Lucius, and now your brother, Draco are both Death Eaters, they both work for the person that's been going after him since he was a baby.
You father, much like he did Draco, forced you to become a Death Eater. Now you had this mark. This god-awful permanent marking on your arm one that claimed you as one of The Dark Lord's loyal followers. You hated it. You just wanted it off, though now, that was impossible.
You hated it so much that you couldn't handle it anymore. You ran away from the Manor where you were supposed to be right now, with the other Death Eaters. You found yourself in a woods.
Harry, Ron and Hermione didn't attend their last year either, they went hunting for horcruxes. They were out camping in a forest one night, so they weren't caught by snatchers or worse, Death Eaters, themselves. It was Harry's turn to keep watch while the others slept inside the tent.
Harry was leaning against a trunk of a tree, reading a copy of the Daily Prophet. That's when he saw it, a bright light glowing from a small pond, beneath the ice frozen water. He carefully walked over, recognizing the figure as one of the horcruxes the group needed to find. Without hesitation, Harry removed his shirt and pants, jumping into the pond, the ice giving way in the pressure and breaking. The water was freezing cold and if that wasn't the worst part, this definitely was. . .
On Harry's neck hung the first found horcrux, a locket. It always gave the wearer bad thoughts, but it seemed it also hated water. Because the second Harry dived beneath the water it began to shake and pull him downwards, not letting him swim back to the surface. So, that combined with the freezing water temperatures was deadly.
You were walking through the same woods as the trio was in, a bag slung over your shoulder. As you walked through the forest, you came across their tent. A pile of clothes, round glasses, a wand and a Daily Prophet copy laying in front of a tree trunk. You looked around and that's when you saw Harry in the pond and you waisted no time pulling him out if the pond, back onto the land.
