"I'm so fucking sick of you."

"Get well soon, princess."

"Get fucked, Riddle."

Three sentences, three venomous insults that cut the room in half—heavy enough in their intensity to make you want to tear through dungeon walls, splintering stone and mortar with bare hands if it means sparing yourself another second in this blasted room, with him.

Detention at midnight—on a Friday, no fucking less—is unheard of. But leave it to your dickhead ex to make the impossible a reality. His fault, of course. Like always.

Snape had turned a blind eye for months. It was only a matter of time before something had to give. An hour unsupervised was as good as you'll get.

Sulking defeat, you sink back in your chair, rough wood digging into your spine as you eye Mattheo with a glare that could rival a bullet. He looks like hell, and it's infuriating how even in that state he manages to look so nonchalant, so maddeningly unbothered—like even exhaustion makes a home on him and he's comfortable with it. Bags under his eyes, scar cutting across the bridge of his nose, those dark curls falling messily over his forehead, white dress shirt wrinkled and open at the collar.

You roll your eyes, a gesture that feels like your only act of rebellion left.

And he notices. Of course he does.

"You haven't changed a bit," he spits, and you know it's an insult. You scowl as he swipes the blood off his chin with the sleeve of his shirt. "Always a bitch to me over something."

Bitch. The name strikes you, but you won't let him see it, won't let him know that it lands. You've bled too many times at his feet for him to draw blood again tonight.

"Am I not allowed to be pissed off that you dragged us into detention? We should be at the party, Mattheo. We should be anywhere but here." You hear the frustration rising in your voice, like it's boiling up from somewhere deep, somewhere you can't quite reach. It's hard not to let it slip, especially when he looks at you like that. "This is so fucking typical of you. You mess up, and somehow I'm the one who pays for it."

For a moment, there's silence, and it almost feels like a victory until you realize he's only biding his time, waiting to strike back.

"You really want to get back there? To that party?" He leans forward, elbows resting on his knees. You long for the chair to break from under him. "After what your new man was caught doing with Lovegood?"

You snort before you can stop yourself, the sound slipping out like a reflex. You hadn't expected that. And quite frankly, it's amusing—no, downright hilarious—that he's clearly been keeping tabs on you and "new man", and now here he is, trying to play it off like he doesn't care. Like it's nothing.

"I'll spare you the insults this once," you mutter, fingers loosening the tie around your neck with a tug. "Because, clearly, you're ignorant to the truth, even if you think you know every goddamn thing." You pause, ripping out your earrings. "He's not my man, so I don't give a shit what he does with who. He ended it last week. Good fuck, sure—but other than that..."

You trail off, making a mocking noise with your lips, a derisive puff of air, as if you could blow away the memory of him as easily as dust off an old book. A Ravenclaw. Brilliant in all the wrong ways—sharp mind, yes, but utterly thrill-less, like he saw you as just another page to flip through, a textbook he was annotating.
