Secrets (Mattheo Riddle x Reader)

The hall

The next day we had an extra class, taught by Ms McGonagall. It was held in the schools ballroom, which I was unaware even existed. All students there, were in Slytherin. The girls were on one side of the hall, and the boys on the opposite side, facing us.
"As you all know the triwizard tournament is coming up." She stated, and was interrupted by a few cheers and whistles from the crowd. "And with the tournament comes the traditional Yule ball." She continued. The excitement in the classroom immediately died down. "Therefore, you are all required to learn how to dance like proper ladies and gentlemen." She explained further. "Now, let's get straight to it shall we? Does anyone here have any ballroom dancing experience?" Around 4 hands rose from the group of students. Including me, and surprisingly, Mattheo. I furrowed my eyebrows at him and he nodded confidently.
"Mr Riddle! Will you please stand and join me in demonstrating the Nevilles waltz?" Ms McGonagall asked him, her hand reached out for him to take.
"Me?" He asked very unhappily.
"Well that is your name, is it not?" McGonagall asked.
A few chuckles spread throughout the classroom. Slowly, he stood, and followed her onto the dance floor. She stood in position, instructing Mattheo of what to do.
"Now put your hand on my waist." She said. And awkwardly, he did as she said. Someone in the classroom whistled. I could barely contain my laughter. I was trying my hardest not to cry. Once the two were in position, the music began. They two began to dance a graceful dance. Gliding across the room. As I watched I caught myself wishing I was up there dancing with him. I shook the thought. At one point in the dance, McGonagalls back was turned to me and I saw Mattheo's face over her shoulder. He looked at me, and I mouthed the word 'nice' to him followed by a wink. He tried to stop himself from laughing as well. The song came to an end, the two split.
"Now you will have a go yourselves. Please stand." McGonagall ordered. The girls stood, and eventually, so did the boys.
We found our partners. Mattheo immediately came my way put his hand out for mine, making me smile. We got onto the dance floor, I put my hand on his shoulder and the other in his. He put his hand on my waist, giving me butterflies. Once every one had split up into pairs, the song began. Some people tripped over themselves, some slowly got the hang of it, and some were already quite good. Those people being me and Mattheo.
"I saw you, looking all jealous." Mattheo told me, smirking.
"Well yeah. There's no way I can compete with that." I said looking over at McGonagall.
We shared a brief laugh.
We began to dance, he led very professionally.
"Wow Riddle, who knew you had such moves." I giggled.
"You don't know the half of it." he flirted with a smirk, before giving me a quick spin. I let out a laugh, and a smile spread across his face.
"Be my girlfriend." He said out of the blue. I looked into his eyes, the cutest smile on his face.
"That didn't sound like a question." I joked around. He rolled his eyes playfully before adding,
"Please?"
I let out a fake sigh and said, "Since you want me so bad..." 
We smiled at one another.  
"But what about the others? I mean it's awkward enough with the whole break up going on right now." I asked him.
"They don't have to know, this can be our secret." He whispered into my ear, making the butterflies much stronger.
The song came to an end, and we stood opposite each other once again.  We had to thank one another for the dance, then we returned tot he hall.
That day was the day that the other schools arrived for the upcoming Triwizard tournament. We were all seated at our house tables, Dumbledore stood to do his daily announcements.
This is when he introduced our guests.
"Please welcome,  the students of our brothers and sisters of Durmstrang Institute and Beauxbatons Academy of Magic." He exclaimed, his voice flying the room.
The hall's doors flung open, and in came buff-looking guys, with very interesting uniforms, and in their hands they held what I believe was a staff. Not too far behind them, were a group of elegant looking girls, in pretty, blue uniforms topped with matching hats. They  reminded me, a bit, of flight attendants. no offence to them.
All of my peers watched the visitors as they walked past, as if they had never seen anything like it in their lives. Murmurs spread through out the hall.
After the headmistress and head master of the other schools had introduced themselves, we continued with our lunch. What had now come to be an everyday thing, was the awkward silence in-between the friend group. Eventually I snapped.
"God, I hate this!" I said, catching all of my friends attention.
"Y/n." Draco hissed at me.
"This is so uncomfortable. What happened?" I laughed a little at the stupidity of what was causing this. No one said anything.
"Some one, please say something?" I pleaded. The others simply looked down at their plates I sighed.
"Fine. Have it your way, just know, you chose this awkwardness." I shrugged and continued to eat.

I was in my last class of the day, however I had already studied the topic that we were being taught. Making me bored out of my mind. I looked at my watch and saw that there was only about 5 minutes left I the session. I raised my hand and asked for a bathroom pass. Really, I didn't plan on coming back. While walking through the halls, taking my sweet time, I spotted a familiar face. Immediately I panicked and began to walk the opposite way, but it was too late. Theo was already jogging after me.
"Hey! Hey!" He called out, finally catching up with me. I ignored him and tried to walk away as fast as I could. He blocked my path.
"Hey, i'm talking to you." He half laughed.  I glared at him, disgusted with how normal he was acting. The night came flooding back to me. I felt like throwing up.
"Get the fuck away from me Nott." I said, walking past him.
"Woah! " He exclaimed, shocked. As if he didn't know why I was treating him like this.
"What's your problem?" He asked, aggravated.
"What's my problem?! MY PROBLEM?!" I laugh. "Don't act like nothing happened! Theo-"
"Wait! What do you mean?!" He asked genuinely.
I turned to take a quick scan of his face, seeing that he really had no clue what was going on I asked,
"Do you remember the twins party?" Through clenched teeth.
"No! I was on some strong shit Y/n! Last thing I remember is getting there."
"Unbelievable." I said, my tongue in my cheek. I turned to leave, and thankfully he didn't follow me.
I stormed to my dorm and slammed the door shut. I felt warm tears streaming down my face uncontrollably. My breaths were becoming shallow, I panicked. My heart pounded in my chest, and I began to tremble all over. I honestly felt like I was going to die. I leant back on a wall and slid down it. My hand over my chest I tried to slow my breathing, but it seemed impossible. The more I panicked the worse it got.
Casper came in through the window, and began to snuggle up next to me, but at this point I was feeling distant and dizzy.
I heard the sound of a door opening and closing.
"Y/n?" Mattheo's voice said, grabbing my attention. I looked at him slowly, he stared worriedly.
"Hey? Hey? What's wrong?" He rambled, squatting down next to me.
"I can't- I can't breathe." I told him.
"Oh... Uh, I'm here." He said calmly, understanding what was happening. He sat next to me.
"Hey, you know what helps when you feel like this? A game." He said, while gently brushing hair out of my face, and wiping away tears with his sleeve. "How about odd one out?" He continued.
I nodded, with a sniffle.
"Alright, I'll go first... Me, Draco, and... Casper." He said, while picking my cat and placing him on his lap.
"Casper. Because he's good looking." I said, followed by a laugh.  Somehow this was working
"HEY!" Mattheo chuckled, hand over heart. "You know what..." he said standing to leave, jokingly. Only making me laugh more. I grabbed his hand and made him sit back down. Not letting go. After a little bit, I felt better. I played with Mattheo's palm.
"Tell me what happened."He ordered.
I took a deep breath.
"I saw Theo." I said, Mattheo's face immediately dropped.
"Did he touch you?" He asked, already enraged.
"He doesn't remember anything, he's being as if it never happened."
Mattheo looked a little more relieved, but was still angry.
"Let's just forget about him." I said, and that's what we did.
