Mattheo Riddle One Shots

Whats mine, is mine

Again not my original work but I heard about Maggie Smith's passing so I'm resharing this post of Mattheo x reader in honor of her passing. (It's sounds bad but I promise it's good) I also can't believe she's gone. I hope she is in a better place now.

Summary: "I'm not the jealous type, but what's mine is mine. End of story"

"What do you think you were doing!?" Boomed the loud voice of Professor McGonagall. "Fighting another student! And breaking his nose! Mr Riddle, it will be detention for a month for you!"

You looked to your boyfriend, a hard look on your face. As you were also mad at the Slytherin boy. Yet he didn't looked faze, maybe a little proud of himself more so. You didn't know why he had to attack the Gryffindor boy.

"And you" McGonagall swings around to you look at you, still mad but a little softer. "You will get detention for two weeks!"

"W-what?" You sputtered. "I-I did nothing, other then try to break them up!?"

"When I came upon the scene, it didn't look like you were breaking it up Miss (Y/L/N). Two weeks detention, another word from you and it will be more, understood?"

You bit your tongue and nodded your head, casting a glare to Mattheo. Who looked quite pleased with himself.

The Professor sighed. "Alright, back to your house you go"

You both got up from your seats in McGonagall's class room, and began to walk to the room's door. Before you even took two step's, the Professor asked for you to stop and wait a moment. She sent off Mattheo, who didn't like leaving you, but he reluctantly left the room. You turned back and moved to stand before McGonagall at her desk.

"Yes Professor?" You asked calmly.

She looked at you with a soft, pointed look. "I am not one to meddle in the lives of students, but are you sure Mr Riddle is the right suitor for you? He is hot headed and easy to anger, that to me is not a good thing".

You understood her concerns and felt touched the women cared, but she did not know Mattheo like you did. No one did. They only saw what he showed them; cocky, tough, smartass and anger issues. But what you have seen of your boyfriend was loyalty, kindness, sweet and passionate sides. Slytherin boy's protected and coveted what was theirs.

"All due respect Professor, you don't know Mattheo like I do" you replied with a confident voice. "He might be what you have said, but you don't know him like I do. There is more to him then just that. Am I free to leave now?"

Professor McGonagall gave you a surprised look before dismissing you. You weren't one to necessarily speak up like you did, and be rather rude to those in authority. But part of her admired your loyalty to Mattheo Riddle. And she hoped you were right about knowing him well.

You walked from the classroom with a sigh. This is not how you wanted your afternoon to go. You didn't want to have to step between your boyfriend, who had came across a Gryffindor classmate asking you for your notes from Snape's class, and another student. Alright, Slytherin and Gryffindor might not get along, but with Henry, you had a mutual respect for each other and your studies.

But Mattheo came upon you both, having a laugh, and looks to have thought Henry was flirting with you. One minute you're laughing, the next Mattheo had grabbed Henry and pulled him away. They exchanged words before Mattheo punched him. And began their fist fight. You moved to break them up, which was hopeless. Soon Professor McGonagall came across you three, as well as the crowd of on lookers. And, well you know what happened next.

"What did she want?" Asked Mattheo, as you came upon him leaning on a wall.

You kept your mouth shut, choosing to ignore your boyfriend and continue walking to the dungeons. A few more times did Mattheo try to talk to you, but you still kept your lips shut tight. Your anger slowly boiling below the surface. When you both descended the stairs to the dungeon did he try again.

"Come on love" he half sighed, half whined. "Talk to me!"

You stopped suddenly – which halted Mattheo – and turned around to shoot him a sharp look. "What can I say to take back the last hour, Theo? Nothing. So what's the point!?"

He flinched at your raised voice. "Come on love" – he stepped up and grabbed your hand, which you withdrew from him a few seconds later – "don't be like this".

"Like what?" You questioned while crossing your arms over your chest.

"L-like this" he moved his hands up and down, gesturing to your stern presence. "This stern figure, when you're not".

You scoffed. "I wouldn't have to be stern if you hadn't attacked Henry".

Mattheo rolled his eyes, "Henry. God his name is worse than his shit fighting skills".

You studied your boyfriend. And after taking in his annoyed tone, agitated roll of his eyes and the fact he'd beaten up your friend but not friend. You concluded one thing about your boyfriend.

"You were jealous" you proclaimed in amusement, having to hold back a chuckle.

Mattheo shot you a glare. "I'm not the jealous type, but what's mine is mine. End of story".

You smirked. "You answered that a little too quick, love" you laughed. And began to head for Slytherin house.

Mattheo sputtered out words, trying to defend himself before finally letting out a frustrated sound. "I was not jealous!" He called before storming after you and your cackling frame.
