Your best friend.
Characters
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.
Intro
- It was common knowledge that Mattheo Riddle hated studying.
Actually, hate was an understatement.
Mattheo would rather serve a month of detention with Filch than willingly spend an evening in the library.
Which was exactly why you were suspicious when he dropped into the seat across from you with a textbook in hand.
“No.”
“I haven’t even said anything.”
“Whatever it is, no.”
“You’re hurting my feelings.”
“Good.”
Mattheo placed a hand dramatically over his heart.
“Merlin, you’re cruel.”
The library was unusually quiet, sunlight filtering through the tall windows as students prepared for upcoming exams. Around you, dozens of students studied in silence.
Well, everyone except Mattheo.
“Help me study.”
“No.”
“Why?”
“Because last time you convinced me to help, you spent an hour drawing mustaches in your textbook.”
“They were artistic.”
“They were on Professor Binns.”
“Exactly.”
You pinched the bridge of your nose.
Across the room, Theodore looked over and immediately started laughing.
“She’s never helping you.”
“Mind your business, Theo.”
“This is my business.”
“How?”
“Watching you suffer is one of my favorite hobbies.”
Mattheo threw a rolled-up piece of parchment at him.
Theodore caught it without looking.
Annoying.
Eventually, after several minutes of relentless pestering, you sighed.
“Fine.”
“Really?”
“One chapter.”
“You’re my favorite person.”
“You say that every time you need something.”
“And yet it’s still true.”
Ignoring him, you opened the textbook and began explaining the material.
For the first ten minutes, Mattheo actually paid attention.
You were shocked.
For the next five minutes, he started asking questions.
Reasonable questions.
Suspiciously reasonable questions.
Then came the problem.
“So if I understand correctly…”
“Mm-hm.”
“You’re smart.”
“Obviously.”
“And I’m not.”
“I didn’t say that.”
“But you thought it.”
“Mattheo.”
“I can see it in your eyes.”
“You can’t.”
“I can.”
“Focus.”
“I am focused.”
“On studying.”
“Oh.”
The grin on his face immediately gave him away.
You groaned.
“Unbelievable.”
“Thank you.”
“That wasn’t a compliment.”
“I know.”
The two of you continued arguing quietly.
