The air in the common room was different. It was warm, smelling of those ridiculous, brightly-flavoured sweets and wood smoke—a stark contrast to the cool, refined stone vaults of the Slytherin dungeons. Draco always felt like an intruder here, a boundary-crosser, and to his own surprise, he found he even liked it. He had almost made it past the armchair by the fireplace, his gaze fixed resolutely ahead, when he heard that voice. The voice that had haunted him his entire life.
“Well, look who it is. My arch-nemesis.”
Draco froze, rooted to the spot. His heart gave a single, sharp, painful lurch in his chest, stealing his breath. Not ‘rival’. Not ‘that slimy Slytherin’. Arch-nemesis. It sounded like something architectural, integral, a load-bearing wall in the very structure of their existence. He turned around, assembling the familiar mask of cold arrogance onto his face. His own retort about the ‘Chosen One’ and the Dark Lord came automatically, a defence mechanism honed over years. Foolish. He knew it was foolish.
And then Potter… smiled. Not mockingly, not gloatingly. But… warmly. And he spoke.
At first, the words hit him as mere sounds: “No. You are my arch-nemesis.” Predictable. Old. But then…
“No one could ever replace you.”
The air stopped reaching his lungs. All the noise of the world—the crackling of the fire, the rustle of pages—vanished, swallowed by the rising buzz in his ears.
“My one and only arch-nemesis.”
And the final, finishing blow, delivered with such monstrous, simple certainty, as if Potter was merely stating the colour of the sky or the law of gravity:
“Mine.”
That single word—Mine—didn’t hit him like a wall, but like a wave of heat. It raised goosebumps on his skin, burned him from the inside out, making the blood rush to his face so fast the world darkened at the edges. This wasn't the heat of anger or shame he knew so well. This was something sweet and suffocating all at once, honey poured directly into his veins.
Mine.
It was so much more than the word ‘enemy’. It was an acknowledgment. A claim. A testament to a connection so deep and unbreakable that all the talk of the Dark Lord seemed like childish prattle. He was a tyrant, an ideology, a nightmare. But this… this was personal. Between them. Only between them.
His entire world, all his understanding of himself and of Potter, flipped on its axis in a single instant and clicked into a new, terrifying place. All those years of fighting, all that hatred and obsession—Potter had just put a seal on all of it. And not a seal of rejection, but a seal of… belonging.
He could feel his face burning and knew it was impossible to hide. His only salvation was flight. He muttered his classic, “Whatever,” but even to his own ears it sounded pathetic, stripped of all meaning and power, just a noise to fill the deafening silence roaring in his head.
He turned and strode away, feeling his back tense and the tips of his ears on fire. But inside him raged not a storm of fury, but something new, strange, and dazzlingly bright. Something that finally silenced the six-year-old boy who had once dreamed of friendship in a robe shop. Because Potter was right. He was his. His arch-nemesis.
And for the first time in his entire life, Draco Malfoy thought that being someone's—being his—might be the sweetest and most unbearable thing in the world.
The following days turned into a peculiar kind of torture for Draco, one that stole his breath and sent shivers cascading down his spine. He, who took such pride in his ability to avoid unwanted encounters, suddenly found himself running into Potter with a frightening, almost magical regularity.
It wasn't coincidence. It was destiny.
In the library, behind the deafening wall of Potions folios, he looked up and met Potter's gaze from the opposite shelf. And Harry didn't look away. His stare, green and relentless as an Imperius curse, was heavy, proprietary. And as Madam Pince shuffled between the aisles, Harry, without blinking, soundlessly mouthed a single word. Just one. And Draco, hypnotized, read it on his lips, feeling an echo of it form on his own: "Mine." Heat flared in his cheeks, and he jerked so violently he nearly sent a stack of books toppling.
During a shared meal, their eyes met again across the Great Hall, over the heads of hundreds of students. And again—that look. Intent, studying, as if Potter was checking to see if his property was still in place. Draco, feeling like a complete idiot, was the first to drop his eyes to his plate, but his cheeks burned, and a single word hammered in his temples: Mine, mine, mine.
But the most powerful blow was waiting for him in the crowded corridor outside the Potions classroom. The press of bodies was so thick they were shoved together for a moment in the tide of students. Shoulder to shoulder. Draco felt the warmth of the other boy’s body through the fabric of their robes and was about to utter a scathing remark when he felt Harry lean into his ear. So close his breath scorched the skin.
And he heard it. Not a silent whisper, not a mouthed word. But a real, quiet, low, and husky voice, meant only for him, drowning in the general hum:
“Mine.”
The word landed not as a taunt, but as an incantation. A vow. It sank into him, seeped under his skin, made his heart beat a frantic rhythm somewhere in his throat. A shiver, sweet and humiliating all at once, wracked his frame. The air felt thick, hot, so hot it was as if he was standing directly in front of a fire.
He recoiled, pushing away from Potter, and stumbled away, blind to everything before him, the word echoing in time with his heartbeat. Mine. Mine. Mine.
He locked himself in his dormitory in the dungeons, pressing his forehead against the cool stone wall, trying to catch his breath. This was insanity. This was obsession. Potter was driving him mad, and he could no longer deny the strange, consuming thirst that rose within him in response to that word. He hated it. And he craved it again. To be someone's. To be his. Even if it meant being his arch-nemesis. Because in that word, in that gaze, there was no trace of hatred. There was only a relentless, undeniable sense of ownership that made Draco's knees weak and his world narrow to a single, unbearably desired green gaze.
He had almost reached the relative salvation of the turnoff to the dungeons when a shadow detached itself from a deep alcove hidden behind a faded tapestry of trolls and a strong hand pinned him against the cold stone wall.
Draco gasped, but the sound strangled in his throat because he instantly recognized the scent—soap, fresh air, and something undeniably electric—and the hard fingers digging into his forearm. Potter.
“What are you playing at, Potter?” he exhaled, trying to pull away, but the movement was weak, almost ritualistic. Deep inside, his entire being had stilled in sweet, agonizing anticipation.
Harry didn’t answer. He moved closer, blocking out the rest of the world. His body was a solid, warm wall pressing Draco into the stone. In the near-darkness, only his eyes burned—two narrowed slits of emerald studying his face, then sliding down to his exposed throat, where a pulse beat a frantic tattoo.
“I see you looking,” Harry hissed quietly, his lips a centimetre from Draco’s ear, making him shudder. “I see you flush. You hear it. Every time.”
“I don’t hear anything,” Draco attempted to snap, but his voice betrayed him with a tremor.
“Liar.” Harry’s breath ghosted over his lips, a cross between an interrogation and a caress. “You hear it. And you’ll hear it again now.”
With one hand, he pinned Draco’s wrist more firmly to the wall; with the other, he pushed aside the collar of his robe. The fingers were rough, calloused, and Draco squeezed his eyes shut, his heart hammering in his throat. He could feel his skin prickling in anticipation of the touch.
But the touch didn’t come. Instead, came pain.
Sharp, searing, wet. Harry’s teeth sank into the sensitive skin at the base of his neck.
Draco cried out—a short, choked sound. It hurt. It was humiliating. But in the wake of the pain came a wave of heat, so all-consuming, so intoxicatingly heady, that his knees buckled, and he would have fallen if Potter hadn’t been so close, holding him against the wall with the whole length of his body.
Harry wasn't just biting him. He was marking him. With a feral, animalistic intensity, leaving a bruise and an abrasion that would tomorrow blossom into a vivid, furious purple mark. A sign that could not be hidden.
Finally, he loosened his grip, pulling back an inch. His breathing was ragged, his lips wet and, Draco felt with a fresh wave of heat, slightly bloodied. His blood. On Potter’s lips.
Harry looked at his handiwork—the already darkening mark on the pale skin—with the same focused, proprietary expression he’d once used to catch the Snitch. Then his gaze lifted back to Draco’s.
“Mine,” he whispered hoarsely, and the word left no room for argument. It hung in the air between them, heavy as lead and sweet as poison.
He released Draco’s wrist and melted back into the darkness of the corridor as silently as he had appeared.
Draco slumped against the wall, his whole body trembling. He raised shaking fingers and touched the wound. The skin burned like fire, pulsing in time with his frantic heart. It hurt. It was awful. It was the most violating and most exhilarating thing anyone had ever done to him.
He slid slowly down the wall to the floor, into the cold dust, unable to move. He sat there, in the utter silence, pressing his fingers to the mark, feeling tears track down his face—tears of rage, of humiliation, of unbearable, all-consuming realization.
He was marked. He was claimed.
He was his.
And for the first time in his entire life, Draco Malfoy felt truly, utterly wanted.
