Whenever they saw each other in between classes between years 1-5, they always made it apparent that they despised each other. It was natural that a Gryffindor and a Slytherin hated each other. People thought nothing of it. But that wasn't really what was going on between the Chosen One and the 17-year-old Death Eater, no matter what anyone thought. Even the boys themselves didn't know what was to happen.
It was sometime in the middle of December when they first noticed that feeling. That electric, static, lovely feeling.
"One moment, Pansy, I left my bag," said Draco Malfoy to the girl he was walking with. She nodded and headed off to the Slytherin common room.
"I left my book behind," Harry Potter murmured to his ginger-haired friend, "Meet you there."
Both boys hurry off to their destinations, their minds on the upcoming Christmas holidays and being free of their classes. Harry is pacing in front of the Room of Requirement, trying to get it to open, when they meet.
"Er, h-hello," says Harry to the unfaltering and slightly sexy gaze of the Slytherin he despises. He is a bit confused as to what he did to make the blond boy look at him in this way.
Draco tries to grunt as a reply, but it comes out sounding as a sigh. They look at each other for an infinite moment more, then look away. Both muttering farewells, they walk away.
Remembering this moment is what causes Draco to do it. He is supposed to ignore this boy; pretend he is scum. But what he does is ask for a moment after Double Potions.
"Yes?" Harry looked uncomfortable; he kept glancing down the hallway that his friends disappeared down moments ago.
"Well, I've noticed that you've been doing...rather well in Potions, and I was wondering if you could help me." Draco avoids the other boy's striking green gaze.
"Erm...Sure, yeah." Surprise is written all over his face.
"How about tomorrow? At the Room of Requirement." Malfoy is already walking away.
"Okay." Harry whispers at his retreating back.
After that first "meet-up", they were inseparable. Everybody was alarmed, even horrified, but soon they became accustomed to it. Draco Malfoy and Harry Potter were more often than not seen together on the grounds during lunch, or talking softly with each other during classes. Because just hearing the sound of each other's voices was much more important than learning.
After Hogwarts, the boys moved into the cheapest place they could find
Sleeping in the same bed as a Slytherin would have seemed dreadful, the Chosen One muses, the day of his 19th birthday. It would have been the worst thing that he could ever do. As the tall, skinny, blond, adorable Slytherin stirs out of sleep, he now realizes he was completely mistaken.
