Your bestfriend
Mattheo Riddle and you have been inseparable since childhood. Long before Hogwarts, before sorting ceremonies and house rivalries, there was always the two of you. Everyone knew it too. The infamous Slytherin duo. Feared, envied, and impossible to separate. Being the son of the Dark Lord came with expectations Mattheo never spoke about. Whenever the topic came up, walls immediately went up. Jokes replaced answers. Smirks replaced honesty. Nobody pushed him—not even his closest friends: Theodore Nott, Draco Malfoy, Blaise Zabini, Pansy Parkinson, Astoria Greengrass, and Lorenzo Berkshire. Well, nobody except you. At Hogwarts, Mattheo had a reputation. Every girl seemed to fall at his feet, and he loved the attention. The arrogant grin, the effortless charm, the constant flirting—it all came naturally to him. Yet somehow, no matter how many eyes followed him through the halls, the only attention he truly cared about was yours.
Which, at Hogwarts, was never a good sign.
By lunchtime, nearly everyone seemed to know about it.
“Apparently she’s from Beauxbatons.”
“No, Durmstrang.”
“I heard she’s transferring into Slytherin.”
“I heard she’s beautiful.”
The Great Hall buzzed with speculation while students exchanged theories.
Mattheo Riddle couldn’t have cared less.
At least, that’s what he told himself.
He sat at the Slytherin table with Theodore, Draco, Blaise, Lorenzo, Pansy, and Astoria, absentmindedly spinning his wand between his fingers.
“You should ask her out,” Lorenzo suggested.
“Why would I do that?” Mattheo replied.
“Because that’s what everyone expects you to do.”
“I don’t care what everyone expects.”
Theodore nearly choked on his drink.
“That might be the biggest lie you’ve ever told.”
“Second biggest,” Blaise corrected.
Mattheo rolled his eyes.
Then the doors to the Great Hall opened.
Conversation immediately died down.
The new student had arrived.
Students stared.
Professors looked mildly amused.
And within seconds, whispers spread through the room.
Mattheo glanced up once.
Then looked away.
Completely uninterested.
“Well?” Lorenzo asked.
“What?”
“Thoughts?”
“None.”
“You’re impossible.”
Across the table, Pansy smirked.
“He’s lying.”
“About what?”
“He already looked.”
“Everyone looked.”
“Not the point.”
Before the conversation could continue, someone sat down beside you.
You looked up from your food.
Mattheo.
“What are you doing?”
“Sitting.”
“There are literally seven empty seats at your table.”
“And?”
“You’re annoying.”
“I’ve been told.”
The corner of his mouth twitched.
For the next several minutes, he remained there, occasionally stealing food from your plate and pretending not to notice your increasingly irritated expression.
Then the new student approached your table.
“Hi.”
“Hi?” you replied cautiously.
“You’re in my Charms class, right?”
“I think so.”
“Could I maybe sit here?”
The seat beside you was empty.
Before you could answer—
“No.”
The table fell silent.
You slowly turned toward Mattheo.
The new student blinked.
“Excuse me?”
“Taken.”
“Taken?”
“Yep.”
“By who?”
Mattheo casually took another bite of your food.
“Me.”
“You don’t sit here.”
“I do now.”
“Since when?”
“Since thirty seconds ago.”
Theodore, watching from across the Hall, buried his face in his hands.
Draco looked exhausted.
Pansy was trying not to laugh.
Meanwhile, Mattheo remained completely serious.
Eventually, the new student walked away, clearly deciding the conversation wasn’t worth the effort.
The second they were gone, you smacked Mattheo’s arm.
“What was that?”
“What was what?”
“That.”
“I don’t know what you’re talking about.”
“You told them the seat was taken.”
“It was.”
“Mattheo.”
“What?”
“You are unbelievable.”
“I’ve heard that too.”
You groaned and returned to your lunch.
Mattheo leaned back in his chair, looking entirely too pleased with himself.
Because while half of Hogwarts wanted his attention, the possibility of someone else taking yours had suddenly become a problem he wasn’t prepared to deal with.
And that irritated him far more than he would ever admit.*
