cold slytherin with a soft spot for a certain hufflepuff
Intro
The rain had a habit of finding Hogwarts before anyone else.
It tapped softly against the stained-glass windows of the library as Mia Blackmore sat tucked away between towering bookshelves, pretending to read Advanced Herbology. Pretending, because she’d read the same paragraph six times and still couldn’t tell you a single word.
She was waiting.
“You know,” a familiar voice murmured from the shadows, “one of these days someone’s going to notice the golden Hufflepuff sneaking into the Restricted Section.”
Mia didn’t look up immediately. She smiled first.
Then she closed her book.
“They’ll notice the Slytherin standing there talking to her long before they notice me.”
Theodore Nott stepped into the dim candlelight, hands buried in the pockets of his robes. There was always something unreadable about him—a carefully crafted mask that fooled nearly everyone.
Not her.
She could tell when he hadn’t slept. When something was bothering him. When his smirks were genuine and when they were armour.
Right now, he looked exhausted.
“You missed dinner,” she said quietly.
“I wasn’t hungry.”
“Liar.”
A corner of his mouth lifted.
“There she is.”
Without another word, Mia reached into her bag and pulled out a wrapped treacle tart she’d stolen from the kitchens.
“I didn’t steal it,” she corrected before he could speak. “The house-elves practically insisted.”
Theo accepted it, shaking his head.
“I think you’re the only person in this castle who worries whether I’ve eaten.”
“I know.”
It wasn’t dramatic.
It wasn’t a declaration.
Just the truth.
The silence between them settled comfortably as rain continued to drum against the windows. Theo leaned against the shelf beside her, close enough that their shoulders almost touched—but not quite.
Not here.
Not where anyone could walk in.
Dating across houses wasn’t forbidden. Plenty of students did it.
Dating Theodore Nott was different.
To most of Hogwarts, Theo was the quiet Slytherin who kept to himself, whose father had a reputation no one liked to whisper about too loudly. People assumed the worst before he ever opened his mouth.
And Mia…
Mia Blackmore was sunshine wrapped in yellow robes. The Hufflepuff who knew every first-year’s name by October. The girl professors trusted without question.
No one would understand them.
Some of the Slytherins already thought Theo was “going soft.”
Half the Hufflepuffs insisted Mia deserved someone “better.”
So they met in hidden corners of the castle.
The library.
The Astronomy Tower after curfew.
The greenhouses at dawn.
Places where they could simply exist.
Theo finally took a bite of the tart.
“It’s cold.”
She gasped dramatically.
“I risked detention for that.”
“It was worth it.”
“You haven’t even finished it.”
“I’m talking about you.”
For perhaps the first time all week, Mia laughed.
A real laugh.
The kind that made Theo look at her as though she’d hung every star over the castle herself.
Neither of them noticed the footsteps echoing down the corridor outside.
Neither of them noticed the shadow pause beside the library door.
Or the pair of curious eyes that caught sight of a Hufflepuff and a Slytherin standing just a little too close together.
By breakfast tomorrow…
Hogwarts might have a new favourite rumour.
