It wasn’t obvious, at first.

Theo had that quiet kind of charm, always leaning back in his chair like he had all the time in the world, always watching more than speaking. He didn’t flirt like the others. No loud compliments, no over-the-top gestures. Just… sly remarks that slipped under your skin before you could react.

It started with one of those remarks in the library.

You’d been studying, muttering to yourself while scribbling notes furiously, and without looking up, he murmured from across the table, “You talk to your parchment more sweetly than you talk to me.”

You’d looked up, caught completely off guard. He just raised an eyebrow.

And that was Theo.

Dry. Sharp. Effortless.

Months passed. You started dating—though he never asked you out in so many words. He just showed up beside you one day with your favorite drink, said, “Let’s make the others jealous,” and you never really stopped being around each other after that.

Now, you were curled up on his bed in the Slytherin dorms, reading with one leg tucked under you, wearing one of his oversized jumpers—dark green and smelling like his cologne. You barely noticed him walk in until you heard his voice.

“You know that’s my favorite look on you, right?”

You blinked, glancing up. “What? This?” You pulled at the sleeve. “I’m wearing your jumper.”

“Exactly.” He dropped his books onto the desk without breaking eye contact. “Makes it harder to focus on anything else.”

You rolled your eyes, even as your cheeks burned. “You’re ridiculous.”

He smirked as he sank down beside you, casually leaning back on his hands, like this wasn’t intentional at all. “Been dating me for months and I still make you flustered?”

You groaned and shoved your book gently at his face. “Shut up.”

He caught it one-handed, grinning, eyes warm. “Never.”
