Your quill scraped across the parchment as you tried to arrange the potion measurements in a coherent order.

Mattheo slid into the chair next to you without saying a word. He leaned in just close enough for your shoulders to brush. “Your schedule’s wrong here,” he murmured, peering over your shoulder at the page.

Theodore groaned. "Every morning they sit closer. This is getting ridiculous."

Blaise snorted. "Yesterday she drank from his cup like it was hers. He didn’t even flinch."

Draco shook his head, pinching the bridge of his nose. "They’re the only two people in this castle who can’t see what’s right in front of them."

You continued scribbling until Mattheo nudged his breakfast towards you. "Here. You didn’t eat enough," he whispered.

"You're ridiculous," you muttered, but you took the toast anyway, breaking off a piece and biting into it without argument.

From the next table, Lorenzo muttered. "She takes his food now?"

Theo shrugged, his eyes still glued to his notes. "He offers every time. Like it’s his responsibility to keep her fed or something."

"Same answer as me," Mattheo said with a grin, looking at your notes. "Knew you’d get it right."

Blaise gave Draco a nudge under the table. "Flirting face. He’s doing it again."

Draco didn’t even glance up. "It’s the only face he’s got these days... and it’s reserved for her."

Theo muttered, exasperated, "We could set the library on fire and they wouldn’t notice."

Lorenzo smirked. "Tempting."

Mattheo’s hand brushed against yours as he passed you a scarf. "Wear it," he said softly. "You’re freezing."

You hesitated, feeling the warmth of the scarf in your fingers. After a moment, you looped it around your neck. The fabric smelt faintly of cinnamon and of something unmistakably Mattheo.

Theo whispered to Lorenzo, "She’s wearing his scarf."

Lorenzo grinned. "Bet he’s perfectly warm without it, too."

Blaise shook his head, muttering, "She could probably take the whole uniform and he’d just let her."

You barely noticed, still lost in your calculations. Then a sudden thud made you flinch. Draco’s book had slammed shut on the other side of the room. "Alright. Enough. Just date already," he said flatly.

"We’re not-" you began.

"Yeah, we’re just-" Mattheo started at the exact same moment.

Your eyes met for just a heartbeat and the world seemed to pause. Something unspoken flickered in his gaze, making your stomach do a little flip. You quickly dropped your gaze back to the parchment, pretending your pulse wasn’t racing.

The room erupted with laughter. Theo launched a crumpled scrap of paper at Mattheo, who caught it effortlessly and smirked. Blaise leaned back in his chair, grinning smugly.

Mattheo nudged your knee under the table. "Your turn to read, trouble."

Across the library, Theo shook his head, muttering to Lorenzo, "They’re actually ignoring us after that."

"Not ignoring," Lorenzo replied with a grin. "They’re in their own little universe."

Blaise added, smirking, "Fine. Let them think we’re imagining it... it makes it more fun to watch."
