The fire crackled in the Gryffindor common room, casting dancing shadows across the worn furniture. Harry sat in his usual armchair, trying to focus on his Potions essay, but Ron and Hermione kept exchanging meaningful glances across the table.
"Just tell him," Ron finally said, nudging Hermione.
"Tell me what?" Harry looked up, suspicious.
Hermione bit her lip. "We have... a proposition for you."
Harry set down his quill. "That sounds ominous."
"It's about Malfoy," Ron said, leaning forward with a wicked grin. "We've been thinking—after everything he's put us through, all the insults, the sneering, the way he's strutted around like he owns the bloody castle—"
"He deserves payback," Hermione finished. Her eyes held an uncharacteristic hardness. "Real payback."
Harry's stomach twisted. "What kind of payback?"
Ron's grin widened. "Seduce him. Make him fall for you. Then break his heart into a million pieces."
The words hung in the air like a curse. Harry stared at his best friends, searching for any sign they were joking. They weren't.
"You can't be serious."
"Why not?" Hermione said, her voice cool and logical as always. "He's been cruel to us for seven years. He deserves to know what it feels like to be humiliated, to have his feelings trampled on."
"Have you seen the way he looks at you lately?" Ron added. "During eighth year, since we all came back? There's something there, mate. He watches you when he thinks no one's looking."
Harry had noticed. The weight of Draco's gaze had become familiar over the past months—lingering, assessing, hungry in a way that made Harry's skin prickle with awareness.
"I don't know..."
"Come on, Harry." Ron's voice took on a wheedling tone. "Think of it as justice. Poetic justice. The great Draco Malfoy, brought low by the Boy Who Lived. It's perfect."
"We'll make it worth your while," Hermione said. "A hundred Galleons if you can make him fall for you and then dump him publicly."
Harry looked between his friends, seeing the vindictive gleam in their eyes. Part of him recoiled from the cruelty of it. But another part—the part that remembered every "Scarhead" and "Saint Potter" and poisonous insult—felt a dark satisfaction at the idea.
"Fine," he heard himself say. "I'll do it."
Ron whooped, and Hermione smiled—a sharp, satisfied smile that didn't quite reach her eyes.
Harry wondered what he'd just agreed to.
---
Draco Malfoy was beautiful.
Harry had always known this on some abstract level, but now that he was actively pursuing the Slytherin, it hit him with full force. Draco moved through the corridors like liquid silver—all elegant lines and aristocratic grace. His platinum hair caught the light from the enchanted windows, and his grey eyes were sharp enough to cut glass.
Those eyes were currently fixed on Harry with obvious suspicion.
"Potter." Draco's voice was cool, measured. "To what do I owe the... pleasure?"
They stood in a relatively empty corridor near the library. Harry had been waiting for Draco to emerge from his Ancient Runes class, and now he felt suddenly, painfully awkward.
"I was wondering if you'd like to go to Hogsmeade with me this weekend."
Draco's perfectly sculpted eyebrow arched. "Hogsmeade. With you."
"Yes."
"Why?"
Harry hadn't prepared for direct interrogation. "Because... I'd like to spend time with you?"
"How fascinating." Draco's tone suggested it was anything but. "And this sudden interest in my company—it wouldn't have anything to do with a bet, would it? Or perhaps a dare from your little Gryffindor friends?"
Harry's heart stuttered. How could Draco possibly know? But the blonde's expression remained merely curious, not accusatory. He was fishing, Harry realized. Testing.
"No bet," Harry lied, forcing himself to meet those penetrating grey eyes. "I just... I've been thinking about you. About us. About what we could be if we stopped being enemies."
Something flickered across Draco's face—too quick for Harry to identify. Then the mask of cool amusement returned.
"How very Gryffindor of you. Rushing in where angels fear to tread." Draco tilted his head, studying Harry like a particularly interesting specimen. "Very well, Potter. I'll go to Hogsmeade with you. But I warn you—I have exacting standards. Don't disappoint me."
He swept past Harry in a wave of expensive cologne, leaving Harry standing in the corridor, heart pounding.
That had gone... well? Maybe?
Harry had no idea what he was doing.
---
Over the next two weeks, Harry threw himself into the pursuit with a determination that surprised even himself. He left notes in Draco's textbooks—carefully worded compliments that made the blonde's lips quirk with amusement. He bought Draco's favorite sweets from Honeydukes and left them outside the Slytherin common room. He complimented Draco's appearance, his intelligence, his wit.
Draco accepted it all with an air of regal entitlement, as though Harry's devotion was only natural and expected.
But Harry noticed things. The way Draco's eyes would soften fractionally when Harry said something genuine. The way he'd lean in slightly when they talked, as though drawn by invisible strings. The way his fingers would linger when their hands accidentally brushed.
What Harry didn't know was that Draco had figured out the bet within the first three days.
It hadn't been difficult. Potter was many things, but subtle wasn't one of them. And Draco had spent years studying Harry Potter—his expressions, his tells, his patterns. The sudden interest, the awkward compliments, the way Weasley and Granger watched from a distance with barely concealed glee...
It was obvious.
And it was perfect.
Because Draco Malfoy didn't get mad. He got even.
Potter wanted to play games? Fine. Draco would play. But by the time he was finished, Harry Potter would be the one on his knees, bound by magic and desire and love so complete it would consume him.
Draco had always been good at long-term planning.
---
"Come with me."
Draco's voice was low, intimate, as he caught Harry's wrist after Defense Against the Dark Arts. His fingers were cool against Harry's skin, and the touch sent electricity racing up Harry's arm.
"Where?"
"Somewhere private." Draco's grey eyes glittered with promise. "Unless you'd prefer to continue this... courtship in front of an audience?"
Harry's mouth went dry. They'd been dancing around each other for weeks now, the tension building with every lingering glance and accidental touch. Harry had almost forgotten this was supposed to be a game, a bet. Somewhere along the way, the pursuit had become real—or at least, it felt real.
"Lead the way," Harry managed.
Draco's smile was sharp and satisfied.
He led Harry through the castle's winding corridors, up staircases and down passages Harry had never noticed before. Finally, they stopped in front of a blank stretch of wall on the seventh floor.
The Room of Requirement.
Draco paced three times, and a door materialized. He pushed it open, gesturing for Harry to enter first.
The room was... intimate. A large bed dominated the space, draped in silver and green silk. Candles floated overhead, casting warm, flickering light. A fire crackled in an ornate fireplace. It was seductive and deliberate, and Harry's heart began to race.
"Draco—"
"Shh." Draco closed the door behind them, sealing them in. "We've been playing this game for weeks now, Potter. Don't you think it's time we stopped pretending?"
He moved closer, and Harry found himself backing up until his legs hit the edge of the bed. Draco followed, predatory and graceful, until they were inches apart.
"I don't—I'm not pretending," Harry said, and realized with a jolt that it was true. Somewhere in the past weeks, his feelings had shifted from calculated pursuit to genuine desire.
"No?" Draco's hand came up to cup Harry's jaw, thumb brushing across his lower lip. "Then what are you doing, Harry?"
The use of his first name sent a shiver down Harry's spine. "I want you."
"How much?"
"What?"
Draco's smile was wicked. "How much do you want me? Enough to make a promise? A vow?"
Harry's mind was fuzzy with desire, with the heat of Draco's body so close to his, with the scent of his cologne and the feel of his fingers on Harry's skin. "What kind of vow?"
"An unbreakable one." Draco's voice was silk and sin. "Promise me, Harry. Promise that you'll be mine. That you'll never share your body with anyone else. That I'll be the only one who gets to touch you, to have you, to make you fall apart with pleasure."
It should have set off alarm bells. It should have made Harry pause, question, think. But Draco was kissing his neck now, teeth grazing sensitive skin, and Harry's ability to think rationally had fled entirely.
"Yes," Harry gasped. "Yes, I promise."
"Say the words." Draco pulled back just enough to meet Harry's eyes. His own were molten silver, intense and demanding. "Say you'll never have sex with anyone but me."
"I'll never have sex with anyone but you," Harry repeated, dizzy with want.
Magic flared between them—hot and binding, wrapping around Harry's chest like chains of light before sinking into his skin. The unbreakable vow settled into his bones, permanent and absolute.
Draco's smile was triumphant.
"Good boy," he purred, and then he was kissing Harry properly, deeply, claiming his mouth with a skill that spoke of extensive experience.
Harry had never been kissed like this. Had never been touched like this. He was a virgin in every way that mattered, and Draco seemed to know it—seemed to revel in it. His hands were everywhere, unbuttoning Harry's shirt with practiced ease, sliding the fabric off his shoulders.
"Have you ever done this before?" Draco asked, though his tone suggested he already knew the answer.
"No," Harry admitted, flushing.
"Perfect." Draco pushed him back onto the bed, following him down. "I'll teach you everything you need to know."
And he did.
Draco's hands mapped Harry's body with confident precision, finding every sensitive spot, every place that made Harry gasp and arch. He took his time, drawing out Harry's pleasure until Harry was trembling, desperate, begging for more.
"Please," Harry gasped, hands fisting in the silk sheets. "Draco, please—"
"Please what?" Draco was naked now too, pale and perfect in the candlelight. He straddled Harry's hips, looking down at him with hooded eyes. "Tell me what you want."
"You. I want you."
Draco reached for his wand, murmuring preparation spells that Harry barely registered through the haze of desire. Then Draco was guiding Harry's hands to his hips, positioning himself.
"Take me," Draco commanded, voice rough with need. "Show me how much you want this."
Harry had never wanted anything more in his life.
He gripped Draco's hips and pushed inside, slow and careful, watching Draco's face for any sign of discomfort. But Draco just smiled—that sharp, satisfied smile—and rolled his hips, taking Harry deeper.
"Fuck," Harry breathed.
"That's the idea," Draco said, and began to move.
It was overwhelming. The heat, the tightness, the way Draco moved above him with practiced grace. Harry tried to match his rhythm, hands gripping those slim hips hard enough to bruise. Draco didn't seem to mind—if anything, he seemed to enjoy it, head falling back as he rode Harry with increasing urgency.
"Touch me," Draco demanded, and Harry wrapped a hand around Draco's cock, stroking in time with their movements.
Draco came first, spilling over Harry's hand with a low moan that was the most erotic sound Harry had ever heard. The sight and sound of it pushed Harry over the edge, and he came with a strangled cry, buried deep inside Draco's body.
They collapsed together, breathing hard, skin slick with sweat.
Harry felt like his entire world had shifted on its axis.
"That was..." he started, but couldn't find words.
"Just the beginning," Draco said, and there was something dark and possessive in his voice that Harry was too sated to question.
---
Over the following weeks, Draco became Harry's teacher in all things physical.
They met in the Room of Requirement almost every night. Draco showed Harry how to use his hands, his mouth, his body to give pleasure. He taught Harry where to touch, how to kiss, when to be gentle and when to be rough.
Harry was an eager student.
He learned that Draco liked to be held down, to have his wrists pinned above his head while Harry fucked into him with increasing confidence. He learned that Draco's neck was sensitive, that biting the junction of his shoulder made him gasp. He learned that Draco could be demanding and imperious one moment, then pliant and needy the next.
He learned that he was completely, utterly addicted to Draco Malfoy.
"Harder," Draco commanded one night, on his hands and knees while Harry took him from behind. "Don't hold back, Harry. I can take it."
Harry gripped Draco's hips and thrust harder, deeper, until Draco was crying out with each movement. The sounds he made were obscene and beautiful, and Harry wanted to hear them forever.
"You're mine," Harry growled, surprising himself with the possessiveness in his voice. "Say it."
"Yours," Draco gasped. "All yours, Harry."
It felt true. It felt real.
Harry had forgotten entirely about the bet. He no longer thought about breaking Draco's heart—the very idea made him feel sick. Instead, he thought about how to make Draco smile, how to earn those rare moments of softness, how to be worthy of the gift Draco gave him every time they came together.
He brought Draco breakfast in bed (the Room of Requirement obligingly provided). He helped him with homework. He defended him when other students made snide comments about Death Eaters and Dark Marks.
Harry Potter was falling in love.
And he had no idea that every moment of devotion, every act of service, every declaration of desire was exactly what Draco had planned.
---
One evening, about six weeks after their first time together, Harry lay in bed with Draco's head on his chest, fingers carding through platinum hair.
"I need to tell you something," Harry said quietly.
Draco stiffened slightly. "Oh?"
"The reason I first approached you... it wasn't entirely honest." Harry's heart pounded. He couldn't keep lying, not when his feelings had become so real. "Ron and Hermione—they made a bet. They wanted me to seduce you and then break your heart. As revenge for... everything."
Silence stretched between them. Harry held his breath, waiting for Draco to pull away, to rage, to leave.
Instead, Draco laughed.
It was a soft, genuine sound that Harry had rarely heard. Draco tilted his head back to look at Harry, grey eyes dancing with amusement.
"I know," he said simply.
Harry blinked. "You... know?"
"I figured it out almost immediately. You're not exactly subtle, Harry." Draco's smile was fond now, affectionate in a way that made Harry's chest ache. "Did you really think I wouldn't notice Weasley and Granger watching us like hawks? Or the way you suddenly started pursuing me out of nowhere?"
"Then why—"
"Why did I go along with it?" Draco sat up, straddling Harry's hips. His hair was mussed from sex, his lips swollen from kissing, and he'd never looked more beautiful. "Because I wanted to teach you a lesson. I wanted to show you what happens when you try to play games with a Slytherin."
Harry's stomach dropped. "What do you mean?"
"The vow, Harry." Draco's fingers traced patterns on Harry's chest. "You promised you'd never have sex with anyone but me. An unbreakable vow. Do you understand what that means?"
The full implications crashed over Harry like a wave. "I can never... with anyone else..."
"Exactly. You're bound to me. Magically, permanently bound." Draco's smile was sharp again, predatory. "And I never made the same promise. I'm free to do whatever—whoever—I want. But you? You're mine, Harry Potter. Completely and utterly mine."
Harry should have been angry. Should have felt trapped, manipulated, used.
Instead, he felt a strange sense of rightness settle over him.
"I don't care," he said, and meant it. "I don't want anyone else. I only want you."
Draco's expression softened, the sharp edges melting away. "Good. Because I don't actually want anyone else either. I just wanted you to understand the position you're in. You tried to break my heart, Harry. Instead, I've claimed your body, your pleasure, your future. Everything."
"I'm sorry," Harry said. "For the bet. For trying to hurt you. I was an idiot."
"Yes, you were." Draco leaned down to kiss him, slow and deep. "But you're my idiot now."
—-
As the weeks turned into months, Harry transformed.
He became the perfect boyfriend—attentive, devoted, always putting Draco's needs first. He carried Draco's books between classes. He saved him the best seat in the library. He learned to brew the complicated potions Draco liked for his skincare routine.
His friends noticed the change.
"Mate, you're completely whipped," Ron said one day in the common room, watching Harry carefully wrap a gift for Draco's birthday.
"So?" Harry didn't look up from the silver ribbon he was tying.
"So it's weird. This was supposed to be a joke, remember? You were supposed to dump him by now."
Harry's hands stilled. He looked up at Ron with an expression that was almost pitying. "I'm not dumping him. I love him."
"You what?"
"I love him," Harry repeated, and the words felt like truth, like magic, like destiny. "I'm going to spend the rest of my life with him if he'll have me."
Ron looked horrified. Hermione, sitting nearby, had gone pale.
"Harry," she said carefully, "you can't be serious. This has gone too far. You need to end it before—"
"Before what? Before I'm happy?" Harry stood, the gift clutched in his hands. "I know what you two did. I know it was meant to be cruel. But it's the best thing that ever happened to me. So thank you, I suppose, for pushing me toward the love of my life."
He left them staring after him, mouths agape.
---
The truth was, Harry had never been happier.
Yes, the vow bound him. Yes, Draco held all the power in their relationship. Yes, Harry had essentially sold his sexual autonomy to someone who had once been his enemy.
But none of that mattered when Draco smiled at him—really smiled, soft and genuine. None of that mattered when they lay tangled together after sex, Draco's fingers tracing idle patterns on Harry's skin. None of that mattered when Draco whispered "I love you" in the darkness, so quiet Harry almost missed it.
Because Draco did love him. Harry could see it in every touch, every glance, every moment they spent together.
The manipulation had been real. The vow was real. But so was this—the connection between them, the way they fit together, the way Harry felt complete for the first time in his life.
"Do you ever regret it?" Harry asked one night, lying in their usual spot in the Room of Requirement. "The vow, I mean. Trapping me like that."
Draco was quiet for a long moment. "Sometimes I wonder if I went too far. If I let my desire for revenge override my better judgment." He turned to face Harry, grey eyes serious. "But then I think about losing you, about you being with someone else, and I can't regret it. I'm selfish, Harry. I wanted you bound to me in every way possible."
"I don't regret it," Harry said. "Even knowing what you did, why you did it—I don't regret any of it. You're the best thing in my life, Draco."
"Even though I manipulated you? Even though I hold all the power?"
"Even though." Harry pulled Draco closer, pressing a kiss to his forehead. "I choose this. I choose you. The vow just makes it permanent."
Draco's arms tightened around him. "I'd never actually leave you, you know. Even if you were a terrible boyfriend, even if you neglected me—I don't think I could. I'm as bound to you as you are to me, just not magically."
"Promise?"
"I promise." Draco tilted his head up for a kiss. "You're stuck with me, Potter. Forever."
"Good," Harry said, and meant it with every fiber of his being.
—-
Three months after the vow, Draco decided it was time.
He'd been patient. He'd let Harry settle into his role as devoted boyfriend. He'd enjoyed every moment of Harry's transformation from reluctant pursuer to completely whipped partner.
But Ron Weasley and Hermione Granger needed to understand what they'd done.
Draco found them in the library, heads bent over a Transfiguration textbook. They looked up when he approached, wariness immediately flooding their expressions.
"Malfoy," Ron said, tone hostile. "What do you want?"
"To thank you, actually." Draco pulled out a chair and sat down uninvited, crossing his legs elegantly. "For the bet."
Hermione's face went white. "How did you—"
"Please. I've known since the beginning." Draco's smile was all teeth. "Did you really think you could manipulate me? A Slytherin? How adorably naive."
"If you knew, then why—" Ron started.
"Why did I go along with it?" Draco leaned back in his chair, the picture of casual confidence. "Because I wanted to teach Harry a lesson. And you two helped me do it beautifully."
"What are you talking about?" Hermione demanded.
"The unbreakable vow." Draco watched their faces carefully, savoring their confusion. "Harry made one. Promised he'd never have sex with anyone but me. It's magically binding, permanent, unbreakable. He's mine for life."
The color drained from Ron's face. "You didn't."
"Oh, I did. And the best part? I never made the same vow. I'm free to do whatever I want, with whomever I want. But Harry? He's bound to me completely. His body, his pleasure, his entire sexual future—all mine."
"That's—that's—" Hermione looked like she might be sick. "That's monstrous. You've trapped him."
"Have I?" Draco's smile widened. "Or did you? After all, you're the ones who pushed him toward me. You're the ones who made the bet, who encouraged him to pursue me. In a way, you sold Harry to me. You gift-wrapped him and delivered him right into my hands."
"We didn't know you'd—" Ron's hands were clenched into fists. "We were just trying to get back at you for being a git."
"And instead, you gave me the love of my life, completely and irrevocably bound to me." Draco stood, smoothing down his robes. "So thank you. Truly. I couldn't have done it without you."
"Harry will never forgive us," Hermione whispered.
"Oh, he already has. And do you know what he said?" Draco leaned down, voice dropping to a conspiratorial whisper. "He thanked you. Said it was the best thing that ever happened to him."
He straightened, taking in their horrified expressions with satisfaction.
"Harry's happy. I'm happy. The only ones suffering are you two, knowing what you've done. Knowing that your best friend is magically bound to someone you hate, and there's nothing you can do about it." Draco's smile was cruel now, sharp as broken glass. "Sleep well with that knowledge."
He turned to leave, then paused. "Oh, and one more thing. If you ever try to interfere with my relationship with Harry, if you ever try to break us up or turn him against me, I will make your lives a living hell. I'm a Malfoy. I have resources you can't imagine. So be smart, and stay out of it."
He swept out of the library, leaving Ron and Hermione staring after him in stunned silence.
---
Harry was waiting in the corridor outside, leaning against the wall with his arms crossed. He'd known what Draco was planning, had agreed to let him have this moment of triumph.
"How did it go?" Harry asked as Draco approached.
"Perfectly." Draco's smile was satisfied, almost feral. "They looked absolutely devastated."
"Good." Harry pushed off the wall and pulled Draco into his arms. "They deserved it. Trying to use me to hurt you."
"My hero," Draco said dryly, but he melted into the embrace.
They stood there for a moment, wrapped around each other in the empty corridor. Harry pressed a kiss to Draco's temple, breathing in the familiar scent of his cologne.
"Do you think they'll try to interfere?" Draco asked quietly.
"No. They know better." Harry pulled back just enough to meet Draco's eyes. "And even if they did, it wouldn't matter. I'm yours, Draco. Completely. The vow just makes it official."
"Mine," Draco agreed, and the possessiveness in his voice sent a thrill down Harry's spine.
"Yours," Harry confirmed. "Forever."
---
Harry woke to sunlight streaming through the windows of the Room of Requirement and Draco's weight pressed against his side. They'd spent the night here, as they did most nights now. The room had become their sanctuary, their private world away from the rest of the castle.
Draco stirred, grey eyes blinking open. "Morning," he mumbled, voice rough with sleep.
"Morning." Harry pressed a kiss to his forehead. "Sleep well?"
"Mmm. Always do when I'm with you." Draco stretched, catlike and graceful, then settled back against Harry's chest. "What time is it?"
"Early. We have time before breakfast."
"Good." Draco's hand slid down Harry's stomach, fingers tracing the line of muscle. "I have plans for you."
Harry laughed, catching Draco's wandering hand. "You always have plans for me."
"And you love it."
"I do," Harry admitted. "I love you."
"I love you too." Draco tilted his head up for a kiss. "My perfect, devoted, completely whipped boyfriend."
"Your boyfriend who's magically bound to you for life," Harry added wryly.
"That too." Draco's smile was unrepentant. "Any regrets?"
Harry thought about it—really thought about it. The vow, the manipulation, the way Draco had turned his cruel bet into a trap that bound Harry completely. He thought about the power imbalance, about how Draco could theoretically be with anyone while Harry was limited to him alone.
And he thought about how none of that mattered. Because he loved Draco with an intensity that sometimes scared him. Because Draco loved him back, fiercely and possessively and completely. Because they fit together in a way that felt like destiny.
"No regrets," Harry said firmly. "Not a single one."
"Good." Draco kissed him again, deeper this time. "Because you're stuck with me, Potter. Forever and always."
"Forever and always," Harry agreed.
And as Draco's hands began to wander again, as they lost themselves in each other the way they did every morning, Harry thought about how strange life was. How a cruel bet had led to the greatest love of his life. How being trapped had set him free.
Ron and Hermione had tried to use him as a weapon to hurt Draco. Instead, they'd delivered him into Draco's hands—and Draco had claimed him, body and soul.
Harry wouldn't have it any other way.
Outside the Room of Requirement, the castle was waking up. Students were heading to breakfast, professors were preparing for classes, and life at Hogwarts continued as it always had.
But inside their private sanctuary, Harry and Draco existed in their own world. A world built on manipulation and revenge, on desire and devotion, on a love that had grown from the darkest of beginnings into something real and lasting.
Harry was bound by an unbreakable vow. But he'd never felt more free.
And Draco, who had set out to teach Harry a lesson, had learned one himself: that revenge could transform into love, that control could coexist with devotion, and that sometimes the best victories were the ones where everyone won.
"I love you," Harry whispered against Draco's lips.
"I know," Draco whispered back. "You're mine, after all. You don't have a choice."
"I'd choose you anyway."
"I know that too."
They smiled at each other—two boys who had been enemies, then players in a cruel game, and finally lovers bound by magic and choice and a love that defied all logic.
It was perfect.
It was theirs.
And it was forever.
