Trouble with hating a Riddle (Mattheo Riddle fanfic)

The new girl

Bree's POV
I wake up in Mattheo's arms. I life my head off his chest and stare at him. Holy shit he looks hot right now with the sun on his hair and him sleeping peacefully.

"Like what you see, Love?" He asks, I jump a little. His eyes are still closed.

"Sorry, I didn't know you were awake." I reply, I try to get up. He pulls me back down on his chest.

"Mmhm. Your not going anywhere." He says, finally opening his eyes. Did his eyes get prettier? Wait, what time is it? Did we miss class?

"It's Saturday, Bree. We have no classes." He says like he was reading my mind. I sigh, laying my head back down on his chest. He starts to play with my hair.

That was a week ago.

Mattheo's been distant, but I've been brushing it off. It probably about his father or school work, but I can't help to wonder if it's about the sex. Until now.

I was walking to the common room when I heard voices and laughing, I turned the corner to see a girl and Mattheo talking. He didn't notice me, but the girl did. (The girl is new, her names Arya)

Arya's POV

I turn to see Matheos girlfriend. And I stop laughing, Riddle notices and looks to where I was glancing.

"Shit." He mumbles and starts to walk over to her, she was already running away, probably in tears, if she thinks he's cheating on her. I grab his wrist, he faces me and I shake my head.

"You know this is what you gotta do to keep her safe, Riddle. Unless you want your father..." I started, Mattheo cut in on my sentence.

"Yeah. I get it, Arya." He grumbles, " Can't we just wait a little bit?"

"Your gonna keep asking that and you know it." I say, letting go of his wrist. "fine. You got today. That's it, I don't want anymore of my family sucked into your fathers sick games." He nods and runs after his girlfriend who's going to hate him tomorrow.

You probably need an explanation. You see, I meet Mattheo Riddle when we were six because I got in trouble with stealing something, I was homeless so Riddle's dad took me in. I found my family again when I was 10, my older brother went with the Dark Lord and was now a death eater. I am one now too because of my brother. The Dark Lord has a plan, knowing that Mattheo is getting weak with Bree. He orders me and Mattheo to 'cheat' on Bree so that she gets heartbroken and Riddle regains his strength. I, personally, don't think Mattheo is weak but what the Dark Lord oders, I do. Just so my little sister isn't sucked into all of this.

I know this is gonna break Riddles heart but it has to be done.
