Taboos were a funny thing. Unspoken, implied, and yet, it seemed impossible to break them- making it all the more thrilling to throw them into the wind. Once broken, they settled in the depths of your heart as secrets, blossoming uncontrollable until your whole stomach was a resting whirlwind of pink rose petals, ready to be triggered at any minute. The memories of last night were like hidden-away treasures, replaying in your mind as you walked up the dungeon steps on your way to breakfast. It was as if you could still feel his hands on your skin, his velvety voice in your ears and see the look of hunger and adoration in his cerulean eyes.

Almost subconsciously, you ran your index finger along your thigh below the school skirt you were wearing and felt your stomach flutter at the reemerging memories of last night. Half an hour ago, you'd woken up, feeling more gleeful than ever and only after a few seconds realizing why. But now, it clouded your mind and projected a silly little smile onto your face. Theo was your boyfriend.

You could barely believe it, which didn't make it easier to sort out the conflicting feelings fistfighting each other in the back of your mind. The risk of going out with Theo, the betrayal Mattheo would feel, and the overpowering delight ignited by the mere thought of him, the image of his face, the whisper of his name. God could not have crafted a more perfect man- or a more unreachable one. Because you didn't dare picture what Mattheo might do to the both of you if he found out.

The corridor was quiet, the distant chattering from the Great Hall above growing ever more clear as you approached it. No one crossed your way, you were quite late. The cool stone beneath your fingertips as you trailed your hand along the wall was grounding, steady, until suddenly, it wasn’t. A firm grip caught your wrist, gentle yet insistent, and before you could react, you were being pulled- not harshly, but with a certainty that sent a spark of electricity through your veins.

You barely had time to gasp before your back met the cool stone, and when you looked up, Theo was there, his body caging you in with effortless ease. His breath was warm against your cheek, his hands meeting the wall on either side of your head. An easy smirk danced around your lips and the glinting in his eyes stirred other, more sinful memories in you. Though it was a much different setting than back then, the hunger in them was the same he'd stared at you with when he'd eaten out as if you were his last meal. “Caught you,” he said, under his breath, looking so damn irresistible with the teasing look in his eyes. He seemed much more casual than usual, as well as in a much better mood, and you could understand why.

“I wasn't running,” you replied in an unconvincing effort to keep your voice steady. You swallowed when he leaned in even further and tilted his head, eyes boring into yours as if he knew exactly what was going on in your mind- how you longed for him, for every bit of him, from his blue eyes to the sharp edge of his voice.

His fingers traced up your arm lazily, leaving you struggling to suppress a shudder, and if the flicker of his eyes was any indication, he was perfectly aware of how he made you feel. “No?” he asked with a knowing smile. “Then why do you look so nervous?” Your breath hitched in your throat when his lips hovered over yours, stilling in silent anticipation. You knew he was making you squirm, was getting you all hot and bothered for him so he would have the upper hand. And you were ashamed to admit that it worked.

In an attempt to divert him and avoid suffocating on the heavy tension lingering in the minimal space between you, you said, “I was just on the way to breakfast,” but it came out like a question and you bit down on your tongue when he raised an amused brow.

The intensity of his gaze made you swallow and blink, but you refused to avert your eyes from his pools of blue, refused to give him the satisfaction. “Oh, were you know?” he asked, voice low and laced with sarcastic humour.

Sarcasm. His defining feature. Sometimes you felt like he walked through life, disregarding all worry and bother with a sarcastic smile on his face. But you knew he could be genuine. His gaze would always be understanding when you sought out consolation with him, his smile gentle when you would tell him about your day. Last night, when Campbell had cornered you at the party, there had not been a trace of humor in his cold demeanor. When he’d eaten you out on that desk, he had looked up at you with such sincerity.

You instinctively leaned into the touch of his hand when it came up to rest against your neck, thumb running over your throat with featherlight precision. “You keep walking the halls in that skirt of yours and someone’s going to snatch you up.”

Unconvincingly, you rolled your eyes at him and his protectiveness. Your skirt was perfectly fine. Maybe it was the one from last year. Maybe it rode just a little higher on your thigh. Maybe you’d wanted him to notice and strain himself all day to not let Mattheo catch him looking at you. Maybe all you’d dreamed about that night was the feeling of his hands working on your cunt, producing the most mind-blowing orgasm you’d ever felt.

“And let me guess,” you said, challengily, and ignored the pounding of your heart against your ribs, “you’re just the right person to keep that from happening?”

Theo dipped down even more, making your eyes flutter shut in the expectancy of a kiss. It came, but it was a mere gentle peck to the corner of your mouth. “No,” he disagreed smoothly, “I’m the only person who is allowed to.”

You had enough. Enough of the tingling teasing of his fleeting touches, enough of the light touch of his lips. Taking initiative, you stood on your tiptoes to meet his lips, but he pulled away, smirking down at your frown. Just a shame you’d discovered how to make him snap last night. Theo smiled as your hand came up to his neck, pulling him down with pleading eyes, and made not the slightest attempt to assist your struggles. So, you had to get out the full arsenals. “Theo,” you whispered, gaze firmly locked on his cerulean eyes. “Theo, baciami.” (Kiss me)

“Maledizione,” cursed Theo through gritted teeth and you knew you’d won. In one fluid motion, both his hands came up to cup your face and his lips clashed onto yours with unknown ferocity. They moved vehemently against yours, eliciting a high-pitched little gasp from you. It made him chuckle into your mouth as his tongue slipped between your lips, taking charge of the kiss.

Though passionate, the kiss was still controlled, no matter how wildly, he still consumed you with meticulous mastery. Every movement of his soft lips, every brush of his fingers, every wandering of his hands was expertly staged to get you riled up. Kisses with Theo were not satisfaction, they were carefully controlled build up. And once you gave into his push, he guided you more and more to a point where you almost moaned against his lips.

One of his hands had wandered down to your hip, then your thigh. Unexpectedly, he gripped the underside of your upper thigh and lifted it, squeezing the flesh between his long fingers. Departing from yours, his lips latched onto your neck, and you pushed wildy against his chest. He broke away, brows furrowed with a hint of irritation, still pressing you against the wall with his whole body and massaging the flesh of your thigh as he held it, lifted up to his waist. “Wh-”

“Mattheo will kill you!” you whispered, voice shaking slightly. Instinctively, you looked up and down the hall. Stupid, stupid, stupid. Anyone could walk by. Even if they were another student, they would spread the news around the whole castle and you wouldn’t be spared Mattheo's wrath. You weren’t sure whether he’d be angrier at his best friend for stealing his sister, or at his sister for stealing his best friend, but you did know you weren’t eager to find out.

Theo only laughed lightly at your grim prediction, and the sound was so entrancing that you forgot to be angry at him. Though they spared your neck, his lips traced your jaw with featherlight kisses. “Worth it.”

You felt your breath grow unsteady, not just because of his wandering hands. Hastily, you looked in both directions, up and down the corridor, listening for footsteps, however distant they may be. “It’s not,” you disagreed, biting down on your lip as his fingers slipped beneath your shirt and the calloused tips ran along your bare skin. “Theo, seriously. What if he hurts you? Remember what he did to Dylan Walker?”

Walker had taken you out on a date once, and for that alone, Mattheo had landed him in the hospital wing with second degree burns and a lung full of lake water. When you’d confronted him about it, he had refused to tell you why and Walker had never exchanged another word with you. “Vividly,” said Theo in a dry voice, not even bothering to glance up at you. “I was there.”

“Wha-,” you gasped in indignation, but a sharp pinch of your stomach between his fingers got the words stuck in your throat.

“He talked trash about you,” he explained in an indifferent voice, as if it didn’t matter at all.

You let out a frustrated huff of breath and dug your fingers harshly into his shoulders. “Doesn’t matter. Just because you beat up people and chop at your life expectancy together doesn't mean he won't do the same to you.” There was now actual panic in your voice as you nervously anticipated the steps, the people. Eyes widening, nudging friends, running off to tell the whole school, maybe even Mattheo himself.

But Theo seemed completely unfazed as he trailed kisses up your jaw. “Aren’t you just irresistible, all worried about your boyfriend, carina.”

The use of the word ‘boyfriend’ almost made your thoughts stutter and a tender bloom blossomed in the pit of your stomach. Right. He was your boyfriend. You couldn't suppress the small smile forming on your lips, and by the look he gave you, he knew exactly what he was doing. Theodore Nott was your boyfriend. Not anyone else’s.

All the girls you’d secretly envied when you saw them walk off with him to his dorm in the midst of a rowdy Slytherin party, his arm around their waists, knowing from the stories they told they had to be in for a good time. The following day, you’d visit him at his dorm to do coursework together and try to shut out the fact that on the very bed you sat on, he’d kissed and fucked a girl that wasn’t you. Your gaze would linger on the crumpled up sheets, picturing it, how he would be towards them. Would he be rough, or gentle? Would he be mean, or sweet? Where would his hands wander, where would his lips caress, what would they whisper into the space between the heated bodies?

And then, his voice would pull you out of your sinful thoughts, as he leaned against the headboard and studied your expression, teasing you for your lack of concentration. You wondered whether he had known how it would seize your heart, the way he smiled at you, the way he looked at you. The mere act of regarding you. It was embarrassing, pathetic even, but you felt no greater love and adoration for anyone.

Theo’s thoughts seemed to have wandered off to similar pölaces. As he guided your lips back onto his, he whispered words in between the kisses that made your cheeks burn. “I want everyone to know,” he whispered, and despite your reluctance, you sighed contently against his lips. “I want everyone to know you belong to me,” he said in a murmur, his front pressing against yours.

You nearly choked on your own spit when his thigh slotted neatly into the space between yours, and you were glad your embarrassing little mewl was swallowed up by his hungry lips. “I want them to know,” he repeated, as if it was a mantra, as he devoured your lips over and over again. “I want them to know who they will have to answer to if they ever mess with you again.”

“But who do you answer to?” you asked, voice barely audible in between the hungry ministrations of his lips.

But he understood, you knew he did, somehow he always did. Because he scoffed lightly and tilted your head to give himself better access to your lips. “Not your brother.”

It was hard to concentrate on his words when his hand squeezed your thigh so deliciously and his hips moved teasingly against yours, driving all thoughts about getting caught right out of the forefront of your mind, leaving only thoughts of him, him, him. “He may be my best mate, but he has no damn say in this,” Theo said firmly, voice barely above a whisper but rich with his baritone. “And he’ll have to accept that you are your own person, and you can make decisions for yourself that are right. Not because he approves of them but because you made them.”

All this was whispered hurriedly against your lips and you barely registered half of it, but still, a certain warmth spread in your chest- and not only in your chest. Theo’s lips departed from yours and he looked down at you, noticing your still worried expression as you returned his heavy gaze. Gentle fingers brushed over your face, over the frown, smoothing it out with a smile. Letting out a long sigh, you contemplated his words.

“Don’t worry,” he said softly, suddenly with such disarming tenderness that you swallowed.

“Alright,” you breathed out, voice still full of doubt. You weren’t at all convinced that Mattheo would accept the fact that you were your own person, and even less convinced that he would resolve the issue without violence. The last thing you wanted was for Theo to get hurt. But then again, they were best mates. Maybe Theo would finally be the one he would accept, he would deem worthy of you. How ridiculous that notion was. The more Mattheo kept you away from boys, the more desperate you got- hence Terry Campbell. But maybe he would see how misguided his previous overprotectiveness was if Theo talked him out of it. After all, Theo was a master of words.

“If you want to risk it,” you finally said, meeting Theo’s gaze steadily, “I won’t stop you. But not now. Not at breakfast. I’m actually hungry and I want to enjoy it without you getting your head torn off.”

“Qualsiasi cosa per la mia principessa,” he said, smiling. (Anything for my princess)

Because it would look suspicious if Theo and you just so happened to arrive at the same time, you let him go first and waited for a few minutes before making your way to the Great Hall as well. It was relatively late when you arrived, many students were already on their way back up to their common room as it was a Saturday and they had no classes to attend.

When you walked into the hall, you spotted your friends as one of the last groups at the Slytherin table. Walking over to them, you were first spotted by Pansy, who lifted her head from Blaise’s shoulder to wave you over with an eager grin. Suspicion curled in your stomach when you saw the excitement in her expression, the eager smile could mean nothing good.

As you approached them, you avoided looking at Theo, who had perched himself on the bench in between Pansy and Draco. You went for the seat opposite him, Enzo and Mattheo making room for you in between them. Theo lounged far more casual than usual, smirking slightly as you sat down next to your brother, his eyes flickering over you shortly. “Took your time getting here, tesoro.”

Your eyes flickered over to Mattheo in alarm- in his presence, Theo usually made use of less romantic nicknames. But Mattheo didn’t seem to have picked up on it, seeing as he didn’t pause in his scribbling on a torn piece of parchment. Somewhat calmer, you picked a piece of toast from a plate, avoiding his piercing eyes to not give anything away. “Shut up, Theo. I need my rest,” you said as casually as possible. “Not all of us survive on caffeine, nicotine and no sleep at all.”

On the opposite side of the table, Theo rested his chin on his palm, propped up on the polished wood. His eyes were dark with amusement as he watched you spread butter on your toast. “Hm,” he made vaguely, voice dripping with insinuation, “Thought maybe you got held up.”

Stiffening mid marmalade application, you looked up from your toast to glared at him. But he had already averted his eyes, as if they had been resting on you by mere chance. Instead, you met Pansy’s gaze, who narrowed her eyes slightly, a suspicious look on her face. Pansy had known of your feelings for Theo for even longer as you yourself had, she had a certain instinct for romantic intricacies. One that now came to your inconvenience, as her attentive eyes, eager to pick up on any further signs, flickered between you and Theo. Then, she turned to you, a misleading smile spread across her features. “How was the party yesterday, darling?” she asked, wiggling her brows, “How was your date?”

Mattheo, who had barely been paying attention up until now, froze next to you, eyes snapping up from the parchment and to you with scrutinizing estimation. Trying your best to look indifferent at the memory of Campbell, one that you had already half suppressed, you shrugged, not meeting Theo’s eye. “It was pretty uneventful. He was a bit of a bore.”

Mattheo seemed agitated. He leaned back on the bench, fingers tapping on the wood restlessly, knee rocking under the table. “You missed the briefing,” he said to you, in a not so subtle attempt to change the topic of conversation. Out of the corner of your eye, you saw Pansy’s face fall. No doubt would she have asked about the details of the evening, but you weren’t that good at lying- especially not to her.

“The what?” you asked, before she could bring Campbell up again, and raised your brows at your brother. Mattheo grinned at your scepticism and draped an arm over your backrest. Years and years living with him had taught you when his smiles could mean no good, and your brows drew together in a frown as he leaned towards you with a smirk.

“The party briefing. We’re throwing one tonight. No, you don’t get a say. Yes, you’re going. No, you’re not bringing some random guy.”

Deadpanning, you took a bite out of your toast. “Didn’t ask for your permission, actually,” you said sharply when you’d swallowed.

With a mock gasp, your brother clutched his hand over his chest. “You wound my pride as your older brother.” You sighed a long sigh. It was pointless reminding Mattheo that he wasn’t even the oldest and him acting like he was most likely stemmed from some deep-rooted control issues- he would never hear it. You exchanged a short look with Theo, who seemed amused at your frustration and quirked his lips at you. It was hard not to smile back.

“Do we really need another party?” asked Draco, frowning, as he cut his toast into neat pieces for consumption. “Didn’t we just have one?”

Pansy, leaning against Blaise, took her eyes off you to roll them at him. “You say that every time.”

“And you always show up,” Mattheo grinned triumphantly, seemingly very content with himself ever since you’d shown so little enthusiasm regarding your date of last night. If only he knew…

“You've got scratches on your neck, Nott,” Pansy said suddenly, making your meandering thoughts snap back to the present. A present in which Theo had frozen mid-stretch. His shirt seemed to have ridden up when he’d strained his arms over his head and indeed, with horror, you noticed the marks your nails must’ve left on him. You felt heat rush up into your cheeks at the memory, but Theo seemed completely unfazed and smirked at her. “Do I?”

Enzo chuckled into his tea next to you, turning a page in his newspaper and glancing up at Theo shortly, a knowing smile on his face. “Rough morning, mate?” A lazy, unbothered smile spread across his face, and you were momentarily awestruck by the glinting in his blue eyes as they reflected the morning sun, forgetting all about Pansy’s watchful gaze. Looking from you to Theo, she narrowed her eyes once more as Theo idly spun his spoon between his fingers.

“You’ve been in a suspiciously good mood all morning.” Blaise grinned at Theo, who didn’t seem unsettled by the attention at all- other than you. “Must’ve been a real good fuck,” Blaise laughed, making the corners of Theo’s lip twitch. Quickly, you looked away from him. If he looked at you with those damn eyes of his now, your reaction would for sure give you away.

But Theo merely raised an eyebrow at Blaise, readjusting his collar. “Why do you care so much about my sex life, Zabini? It’s disturbing.”

Even Draco now joined into the conversation, and you could only pray your silence would be interpreted as tiredness, rather than nerves and utter embarrassment. He leaned back and frowned slightly at Theo, who was pouring himself another cup of coffee. “It’s just weird when you smile, Nott.”

That seemed to finally take Mattheo’s mind off the party- though you’d rather have them all occupied with something else. He pointed his fork at Theo, suddenly interested. “Actually, yeah. What’s with you?”

Theo deadpanned, sipping his coffee and scanning them all over the rim. “Maybe I’m just happy.”

Next to you, Mattheo snorted disbelievingly. “You’re never happy.” The sarcastic look on Theo’s face made everyone, including you, laugh. Even Theo’s lips twitched humorously and once again, his eyes found yours for the split of a second, brow raising.

“Alright,” groaned Mattheo, matter of factly, once the laughter had subsided, and rose from his seat. “I have some orphans to cannibalize before noon.” his gaze landed on you, voice casual but suddenly firm. “No bullshit tonight, yeah? I don’t want to have to drag some idiot off of you.”

“How about you don’t do that?” you suggested dryly, knowing he would never even consider the possibility. He considered your business his business and justified it by spewing stuff about protecting you, shielding you from the world. But he had to know he would not be able to forever. And you, for your part, were perfectly content with pushing more boundaries, especially when it had felt so damn good yesterday.

As you had suspected, all you got from Mattheo was an unbothered grin. “Not up to you,” he said, simply.

Even Pansy rolled her eyes now. She had always been your advocate, the one who got you talking to boys at parties and smuggled you drinks, lended you her unholy book collection and gave you makeup tips. Now, she gave Mattheo a pointed glare. “You act like she’s a kid, but she’s an adult just like you, you big idiot,” she snapped.

Indignant, Mattheo crossed his arms over his chest. “No, I act like she has terrible taste in men.”

“He does have a point, darling,” Enzo chimed in from your other side, and you gave him a look, conveying just how unhelpful he was being.

“She’s going to end up with someone eventually,” Pansy pressed on, making Mattheo’s expression shift into one of irritation. “And you’ll have to face it.”

Mattheo scoffed, returning her glare. “Not if I have a say in it.”

“You don’t!” you reminded him, voice more heated than before. The stress of keeping a secret from him paired with the worry this conversation sparked off inside you.

The smile on Mattheo’s face was forced, his jaw clenched and his eyes hard and unyielding. “It’'ll be a cold day in hell before I let some idiot get near you." And unfortunately, you believed him.

The Slytherin common room was buzzing with restless, pent up energy of countless students of all houses. The air thick with cigarette smoke and the sickly-sweet smell of smuggled firewhiskey. The emerald glow of the fires cast wildly dancing shadows against the walls, where the portraits had left their frames to spent the night somewhere less in risk of being splashed with alcoholic substance. A large mass of people was swaying to the deafeningly loud music in the center of the room, and in the corners, intertwined bodies engaged in far riskier affairs.

Theo stood against the far wall, posture deceptively relaxed, grip tight round the bottle of some alcohol he was holding. When Blaise had pushed it into his hands an hour prior with a promising smirk, guaranteeing him it was “good stuff”, he had been too distracted to question it, but he didn’t recognize the taste. Normally, that would have been enough of a reason to discard the bottle- Slytherin parties were notorious for the impending risk of being poisoned- but tonight, he couldn’t bring himself to care, needed the deliciously burning trickle down his throat and distract him from this. From you.

His jaw clenched every time he caught sight of you- twirling absentmindedly to the music, smile shining beneath the lights as you let Pansy drag you all over the dance floor in search of Blaise. Unaware of the way his gaze followed you like a magnet, like a tether he couldn’t sever. Every now and again, his eyes flickered over to the opposite end of the room and he took another sip of the unknown drink. Your brother was as loud and reckless as ever, downing shots and laughing with Enzo about something while Draco stood stiffly beside him, eying the dancers critically.

He had been working them out all afternoon. The words, that now sat heavy on his tongue, burning hotter than the liquor. Theo exhaled slowly, set his bottle down with a muted clink, and pushed himself off the wall. The crowd of dancers shifted around him, bodies moving in a drunken haze, some girls clinging to him, but he barely registered it. He slipped through the chaos like a shadow until he came to a stop behind Mattheo and Enzo, still caught up in their conversation.

When they took notice of his presence, Mattheo turned to him with a crude grin. “Enjoying yourself?”

“Plenty,” said Theo dryly, hiding his twitching fingers in the pockets of his trousers. Mattheo seemed to take notice of his restlessness, an impressive feat, taking into account how many shots he’d already downed. His brows lifted in vague confusion. “Need something?” he asked, voice rough from smoke, head tilting as he noticed the tension in his best mate’s stance.

Theo swallowed, throat tight, pulse a heavy drum in his ears- or was it the music? “Yeah,” he finally said, voice low and steady, masking the way his heart rattled against his chest like it wanted to break from its cage. He tipped his chin toward the stairs, toward the shadows of the quieter corner. “Need a word.”

Though he looked surprised, Mattheo gave a small nod and placed his drink on a couch table. He followed his best mate along the cold stone walls that seemed to swallow the loud thumping of the music. When they reached the stairs and immersed themselves in the shadows, the music seemed to grow slightly fainter, though still a prominent beat mirroring the one of Theo’s pulse. “I’ve got to talk to you about something,” he said, seriously, leaning against the wall and scanning Mattheo, gauging his mood, how quick he would be to snap.

Mattheo had had a great evening so far. He’d dunked one guy's head in the punch bowl, made out with both of the Patil twins and the firewhiskey from their new supplier was way better than the one they usually got from the hogshead. He sniggered at Theo’s grave expression. “What are you so serious for, Nott?” he drawled easily, already tipsy from the few rounds of firewhiskey. “Could we have one night where you don’t look like your nonna was just run over?”

Theo made no effort to conceal his scoff. Usually, he had his fun at these parties. Even if he didn’t present the most cheerful face, his needs would remain somewhat satisfied by the end of the night. He highly doubted that tonight would be the same. “It’s about your sister,” he said steadily, watching Mattheo’s grin change into a frown.

“Ah,” he said, sounding somewhat sobered up. “Heard you sorted out Campbell pretty bad this morning. What did he do?”

Vivid images of your wide, teary eyes flashed in Theo’s eyes, of the way that tramp Campbell had grabbed you, how pathetic he had looked this morning as a bloody, crumpled mess at his feet, begging for mercy. “No matter,” he said, remembering his promise to you. “It’s something else.”

“Merlin, Nott, you ‘re acting like she caught a deadly disease,” groaned Mattheo in exasperation, but Theo could see how his vague wording unnerved him. If there was one person Mattheo would burn down the world for, it was his sister. Theo understood the sentiment, but he didn’t like his practices. “Spit it out,” growled Mattheo, pushing himself off the wall to come closer. “Can’t be too bad, can it?”

“It can,” Theo said with pursed lips, knowing that the news he was about to share would bother Mattheo more than a natural disaster could- after all, he was one himself. Mattheo's face fell with the words, and his frown only deepend. “Why do I feel like I’m about to hate whatever comes next?”

It was the way Theo stood so still that caught your attention- a statue carved from tension, jaw locked, shoulders taught beneath his shirt. You almost missed it, lost in the relentless pull of the music and Pansy's hand tugging yours as you spun, but something inside you twisted, as if instinct was dragging your gaze to the far side of the room. and there they were. Theo and Mattheo, cornered in the shadows, their heads inclined towards each other. It was hard to read their body language through the sea of dancing people and flashing light, but you could make out the way Theo’s lips moved, wrapped around words that seemed to struggle their way past his lips.

In reaction to them, Mattheo leaned in, gaze dark and sharp, while Theo's fingers curled into fists at his sides, the muscles in his forearm twitching like live wire. The room around you seemed to blur at the edges, the pulse of the music fading into a distant hum. You couldn’t hear the words exchanged, but you didn’t need to to know that something was very, very wrong.

With a tug at her arm, you caught Pansy’s attention and inclined your head toward their tense figures. Pansy, who had lived through her fair share of dragging Mattheo away from fights, like all of his close friends, frowned, nudging you away from the thick knot of bodies that was the center of the room. Suddenly, your eyes caught the way Theo said something to Mattheo that made his jaw fall slack. Dread pooled in your stomach, your legs uncoordinated with the conflicting wishes to run or to get in between them. You decided upon the latter, slowly walking towards their corner as Mattheo’s hands curled into fists at his sides.

Mattheo laughed in Theo’s face, but it was devoid of any humour, no more than the promise of something darker, of impending doom. “You're joking,” he said, almost commanded.

Theo’s voice was steady, his gaze unwavering. “I’m not.”

But Mattheo seemed unwilling to accept the truth of his words. Shaking his head with a wild smile, he paced around the very limited space, knuckles turning white around the bottle he was holding. “No, no, no. You’re not.” But the hard look on Theo’s face made his face fall. The color seemed to vanish from his cheeks. Without a warning, his hands reached out and suddenly got a hold of the taller boy’s collar, the bottle meeting the ground with a soft thud that was drowned out by the music. Theo looked unfalteringly into Mattheo’s eyes that flickered between, desperately in search of a lie, a bad joke. But it didn’t come, and his group tightened on Theo’s shirt.

“Tell me you’ll end it,” he said, voice low and furious. “Right now.”

Theo didn’t flinch, though his eyes flickered to the side, where some partygoers had taken notice of the unfolding scene. Somewhere in the crowd, he made out your face, eyes widened in worry, as you approached them. “I won’t,” he said harshly to the other.

Mattheo’s face twisted into something sinister, a storm of fury darkening his features, cackling tension ready to break and unleash its fury. His knuckles whitened around Theo’s collar as he dragged him down until their foreheads almost touched. The dancing light of the common room danced around the sharp, clenched line of his jaw, the cold fury brimming in his eyes, and something else- betrayal. “What did you just say?” he breathed, voice dripping with quiet, lethal rage.

But Theo didn’t flinch, his jaw set, eyes steady. “I won’t,” he repeated, voice like iron. Mattheo’s fingers flexed, and it was all it took for his restraint to snap.

The first punch landed like a gunshot. Theo’s head snapped to the side, a sharp crack echoing through the corner of the room as Mattheo’s fist connected with his cheekbone. The force of it staggered him, but he didn’t fall- just wiped the blood from his split lip and squared his shoulders like he’d been waiting for this. Mattheo lunged, grabbing him by the shirt again and shoving him into the storm wall with enough force to rattle the torches. “You absolute piece of shit!” he spat, words laced with venom. “You fucking knew she was off limits!” His voice had risen to a loud snarl, sharp enough to cut through the party noises.

Theo shoved back, and the people broke apart when Mattheo and he faced each other, panting. Slipping from their haze, many of the party-goers turned in search of the origin of the shouting, and a crowd formed around them. And still, Theo didn’t back down. Didn’t say a word. He just stood there, blood smeared across his jaw, staring back at Mattheo like he’d let him tear him apart before he even thought of walking away from you.

But before Mattheo could deliver another punch, a familiar voice made the both of them whip around. “Mattheo, stop!” you shouted, out of breath, and stumbled in between them, into the no man’s land between their heaving bodies. When you looked at Mattheo, you saw the betrayal deeply etched into his features. They were twisted with hate and anger, every nerve tense, like a predator ready to pounce. When you turned to Theo, his heart clenched with a sharp pain far surpassing the one pulsing in his busted lip. Your eyes were full of worry and fear, clinging to the smear of blood on his chin.

But you turned to Mattheo sharply, likely sensing that he was just about ready to do everything- anything. His dark eyes were locked on Theo, he barely acknowledged you, his voice laced with disgust. “You had every girl in the castle, and you chose her?”

“I didn't choose,” replied Theo, suppressing the urge to pull your shaky figure into him, wrap his arms around you. “It just happened.”

“Yeah?” asked Mattheo, chest heaving with barely contained fury. “Well, it’s about to un-happen.”

“This isn’t just some fling, Mattheo,” you tried, taking a hesitant step towards your brother. But not even your pleading eyes could calm the storm raging inside him.

A bitter laugh left his throat, mocking you. “Right. Because you’re so special, huh? Always desperate to be wanted by someone.”

You knew he didn't mean it. That fury and shock twisted his words into something ugly and hurtful, meant to attack your weak points, meant to hurt. To disarm. And it was disarming. His words were like poison, seeping into your flesh, curling up in your stomach and echoing in your mind. Defensively, you squared your shoulders, but tears stung in your eyes.

For a moment, Mattheo almost seemed to falter, until Theo brushed past you in one fluid motion, gripped the collar of his shirt and slammed him against the nearest wall. “What the hell is wrong with you?” he asked sharply, shaking him by his shirt. Instead of an answer, Mattheo shook him off and threw a punch that Theo dodged. The next, however, met him square across the face as Mattheo lunged at him, absolutely livid.

The crowd gasped and screamed as they fell to the ground in a huddle of arms and legs, spitting insults at each other. When Theo rolled him over and got the upper hand for a second, he brought his fist down upon mattheo’s face and the following crack resounded against the stone walls. Spitting out blood, Mattheo shoved him off and tackled him with new fury.

Suddenly, you felt a strong tug at your arm, and before you knew it, Pansy had pulled you a few feet distance from the fight.

Meanwhile, both Mattheo and Theo got onto their feet again and Mattheo, face and shirt bloody, stumbled back a step, steadying himself against the wall. Theo stood upright, but his lip was dripping with blood and his shirt was ripped slightly. Mattheo’s eyes wandered from you to Theo, still ablaze with rage. but instead of attacking him again, he spat at Theo’s feet, turned on his heel and approached the exit, the crowd bursting apart where he walked.

When the entrance sealed itself behind him, stunned silence filled the room, thick as the previous heavy beat of the music. But someone had stopped the record player. The room seemed weirdly small without the thundering bass. Still rooted to the spot, Theo ran a bloody hand over his busted lip. Then, he slowly turned. When you looked into his eyes, you released a shaky breath. Slowly putting the pieces together, a round of whispers overtook the bystanders. And in one singular motion, all heads turned to your heaving figure.

The sad remains of some of the stargazing instruments lay scattered across the floor, unfortunate witnesses to Mattheo's wrath. Ripped parchment fluttered like the wings of trapped birds in the wind and the black board exhibited a large gash where he’d punched it in a fit of overflowing rage. They all were signs of the destrcutive storm that had rushed through, left nothing untouched. Now, it leaned against the stone railing, the remains of several cigarettes at his feet. But no smoke curled in the air above. Mattheo had smoked his lungs out until the pack was empty, and now, his leg rocked unsteadily, his fingers twitched and he glowered into the dark of the night.

He didn’t bother looking up when he heard Theo’s footsteps scuff against the stone floor, the creak of the door. His eyes remained fixed on the horizon like the stars might calm the fury blistering under his skin. But as the other neared the railing with slow but sure steps, he tracked every movement: the stiff set of Theo’s shoulders, the way he flexed his fingers like he was still shaking off the urge to hit something. His jaw was tight, a faint bruise blooming along his cheekbone, but he stood tall, steady, like he wasn’t the least bit sorry for what he’d done. It pissed him off, almost as much as the fact that he was in the wrong.

His eyes wandered down to his best mates hands once more, gaze flickering over the knuckles Theo hadn’t bothered to heal. “You look like shit,” Mattheo muttered, voice low and sharp, though the words carried less venom than they should have.

Theo rested his forearms against the railing next to him, though keeping a certain distance. His hands wrung, more blood seeping from his bashed in knuckles. Then, with a long sigh, one of them disappeared into his pocket and he glanced over at Mattheo, sizing him up. “Smoke?”

Mattheo gritted his teeth in frustration, hands curling into fists as he stared onto the lake. “Fuck yeah. I’ve run out.”

A rustling of clothing, a crackle of carton and then, Theo handed Mattheo a cigarette. The latter took it without comment, lighting it with a flick of his fingers and taking a slow drag. Smoke billowed out of his mouth as Theo next to him balanced another smoke between his bleeding lips and clicked a lighter to ignite it. He, too, took a languid drag of it, watching the smoke curl up into curious shapes before dissipating into the cool night air. As the calming effect made him able to stop the bouncing of his leg, Mattheo let out a scoff and blew smoke from his nose. “You really are a fucking bastard.”

For a few seconds, only the faint whisper of the wind around the castle walls filled the air. Then- “I can only promise you that I’ll be whatever she needs me to be,” Theo replied, carefully choosing his words.

A disbelieving, ironic chuckle stumbled past Mattheo’s lip, hanging in the tense air between them like the puff of smoke that accompanied it. “Well, aren’t you all righteous all of the sudden?”

Theo didn’t answer, but the lack of a response sounded as loud as a yell could have. Agitated, Mattheo tightened his grip on the cigarette, making sparks of embers gush from it and shine brightly until they were swallowed up by the dark. A frustrated growl left his lips. “Why did you have to fuck this up for me?”

“Fuck what up?” asked Theo, a sudden and unmistakable sharpness in his voice that made Mattheo turn his head to him. His brow was raised as he breathed out a string of smoke and eyed the other critically. “Your carefully crafted plan to validate yourself by keeping her close? Whether she's protected or not doesn't change who you are. But I don't think you really care about protection, do you? You only want to be her highest priority, because you’re no one else’s.”

Theo’s voice had grown more heated and he had inched closer. With a frustrated frown, Mattheo averted his eyes from him, angrier than ever at the fact that he knew there was truth to his words. But theo didn’t let up as he leaned in, forced Mattheo to hear the words. “You cling to her like it's her job to soothe your self-loathing. But she's not your mother, she's not your therapist, she's not your tool. I know you love her, so do I, but that means separating your protectiveness from your self-protection.”

There was another short silence, a silence thick with tension, brimming with their heated tempers. Finally, Mattheo scowled frustratedly and took another, long drag of his cigarette. His leg had started bouncing again. “You really are an asshole, Nott.” He waited for an answer, but Theo seemed to have said all he intended.

Agitated, Mattheo ran a hand through his dark curls, voice dropping to a harsh whisper. “Fuck, maybe you’re right. You know… in my whole damn life, the only people who ever accepted me- ever really accepted me- were you and her. You two saw the whole, stinking pile of shit that I am and you chose to stay. And now, you’re going behind my back.” He refused to meet Theo’s measuring stare, knowing he was too disconcerted to put up any sort of facade- especially around him. He’d never really fooled Theo, and it showed when he raised his voice.

“You’re scared,” he said calmly, throwing him a firm look when he scoffed, “Don’t be stupid, you can’t deny it. Just listen to yourself, mate. But being with me doesn’t mean she’ll leave you.”

A frustrated groan left Mattheo’s throat, his eyes fixed to the glint of moonlight, reflected on the steady waves of the lake. They rippled softly with each breeze. “Feels like you’re both turning your backs on me, just like the whole fucking world did,” he said, voice raw, fingers tightening around the railing until his knuckles stood out white.

“They turned on her too,” Theo argued sensibly, voice calmer and somehow softer as the topic turned to you. Mattheo noticed it with great dissatisfaction. “You only see your pain, Mattheo, but you didn’t soothe hers when you made her unapproachable to everyone but us.” Everything inside Mattheo denied the truth his words carried. After all he’d sworn himself he’d do for you, it hit him like another punch. But he was forced to admit that there was some sense in his words.

He’d always thought he alone could protect you properly- and Merlin, it stung that he might be wrong. Who was he kidding, he was wrong. “Shut the fuck up,” he gritted through clenched teeth.

Theo simply stomped out his cigarette, tone turning matter-of-fact. “I have nothing more to say. And you don't, either.”

Mattheo released a frustrated breath of air, scowling at the smoldering cigarette between his fingers. “How did it happen anyway?” he finally asked.

Theo dragged a hand through his curls. He leaned against the cold stone railing, jaw tight, voice low but steady. “It only started last night. At Slughorn's stupid party,” he admitted, glancing at Mattheo through the haze of smoke.

“I thought she went with Campbell?” asked Mattheo, quickly, and Theo narrowed his eyes at him. “I was getting there.” Averting his eyes to his hands, his expression darkened at the memory of the night. “Campbell cornered her. He had his filthy hands on her, saying things I won’t repeat. I got there just in time.” His voice sharpened, every word laced with venom. “Ripped him off her. This morning I made sure he wouldn’t forget why he shouldn’t try again.” Theo rubbed his thumb over his knuckles that were becoming scabby against the cool air. “She was shaken, mate. And you weren’t there. But I was. And I couldn’t- couldn’t leave her after that.”

Mattheo didn’t speak. The only sound was the distant crackle of the dying embers in his cigarette, the quiet rustle of wind tugging at their robes. He stood rigid, fingers curled into fists at his sides, jaw clenched so tightly a muscle ticked beneath his skin. Theo stayed still, letting the weight of his words linger, his chest rising and falling in slow, measured breaths. He didn’t look away, didn’t flinch under Mattheo’s glare- just waited. And when Mattheo finally exhaled, the sound was sharp, almost guttural, like he was trying to breathe out the ache that had settled in his bones. “What did you do to Campbell?” he finally asked in a business-like manner, though his glare was withering.

“Broke his nose. His jaw. Split his brow. Might've kicked a couple ribs in,” Theo said, deadpanning.

Mattheo paused, nodding slowly. “Good.”

“I don’t just care about her,” Theo pressed, seizing the moment as Mattheo looked somewhat appeased. “I protect her. I have and I will.”

Mattheo scoffed, but when he glanced back at Theo, his glare had turned into a frown, fury replaced by irritation. “You broke my nose, by the way,” he said gruffly, pointing to his blood-smeared face.

“You split my lip first,” countered Theo with a smirk, rubbing over his knuckles.

The reply earned a dark chuckle from Mattheo. “Fair trade for wrecking Campbell’s face, I guess.” With a sigh, he turned to lean against the railing with his side, his front turned towards Theo. With a flick of his wrists, he flicked ash into the night and studied Theo’s expression. “I get it, you know. Why she… why you.”

Theo glanced over, catching Mattheo looking almost pained at the admission. “Do you?”

Another groan left Mattheo’s lips as he flicked the burnt-out smoke off into the dark grounds of the castle, following the glowing embers with his eyes until they had merged with the dark. “I hate it,” he said lowly, “But yeah. i get it.” His eyes seemed to darken. “If she’s gonna be with someone, I’d rather it be the guy who fought me for her without flinching.”

The agitation was visible with the way his knee bounced, his fingers twitched and he averted his face from Theo’s piercing gaze. When he spoke again, his voice was barely above a whisper. “Take care of her, man. Please.”

When Theo opened his mouth to speak and reassure him, however, he cut him off quickly, voice wavering slightly with the struggle to hide how affected he was. “You won’t have sex of course.” His face twisted with disgust at the idea. “Not until she’s at least twenty-five. Thirty. Never, actually,” he clarified, nodding to himself and giving Theo a very firm glare, pointing at him. “Don’t you lay hands on my little sister!”

“She’s not your little sister, mate,” said Theo, completely unfazed. “And it may already be too late for that.”

“You fucker!”

Theo descended the stone steps from the Owlery, hands stuffed into his pockets, the early morning chill clinging to his skin. A few students he passed nudged their friends and broke out into whispers, but he ignored them. It had only been a few hours, but the news of his and Mattheo’s showdown at the Slytherin party had already made its rounds. Not that he would have minded. The more people knew you were his, the better. It was as if his whole terrifying reputation had been crafted only to protect you now.

As Theo stepped into the nearly empty Great Hall, he spotted you sitting alone with Mattheo at the Slytherin table. The sight seemed to unravel something inside him. You were curled into the bench, hands wrapped around a mug, face lit with cautious disbelief. Mattheo sat back, arms slung over the back of the chair, looking exhausted but...relaxed. Like the weight of the world had shifted off his shoulders, even if he wasn’t quite sure where to put it yet.

Theo hesitated only for a second, then he walked over, passing all other house tables and walking up the Slytherin one. When you noticed him, your eyes widened, your lips parting as if you couldn’t quite believe he was still breathing, still standing. “So Mattheo wasn’t lying,” you said, breathlessly, looking up at him. “You actually survived.”

Theo’s lips twitched into a crooked grin as he dropped onto the bench beside you, thigh brushing against yours like it belonged there. "Told you I could be convincing," he muttered, voice low enough that Mattheo rolled his eyes but didn't argue.

Glancing shortly at Mattheo, you leaned over to place a quick peck on his lips- unaware how hungry it made him for more. With a sheepish smile, you parted from him, and he had to seriously restrain himself in order to not grab your face and clash his lips onto yours, making your breath hitch so deliciously in your throat.

Mattheo tossed a piece of toast onto his plate glaring at Theo like he still might throttle him for sport, but his voice lacked venom. “I told her if you break her heart, I'll break your legs,” he said, like he was commenting on the weather.

Theo just smirked, stretching his arm across the back of the bench, fingers ghosting over your shoulder. “Fair trade,” he murmured, turning to you with a glint in his eye. “Guess you’re stuck with me now, huh?”

And the way you smiled back- hesitant, relieved, a little in awe- made every bruise worth it.
