The Weight of a Letter(Yandere!Rottmnt Donnie x GN reader)

A Dirty Liar

Content warnings: None I think? Idk, school, possessive hints, slight paranoia

I moved through the motions of the day in a quiet buzz. Staying up all night talking to Mikey was fun, but ended up being a bit of a mistake. I could barely sit through each class. I fiddle with the rose I had received this morning along with another letter. It is beautiful, yes, but I'm starting to get unnerved. Today's letter feels... Off. I don't know how to describe it, but it doesn't seem like the others. The sense of admiration and love was still there, but so was a hint of obsession. Danger, even. I glance down at my bag by my feet, shifting in the chair. My letter was sitting just inside the zipper, begging to be read through again. I doubted I could. One of the lines kept sounding through my head, making its way into every thought.

I can't wait to make you mine for good.

I look down at the flower, frowning slightly. It wasn't too bad of a line, almost innocent on its own. But reading the letter, with the surrounding thoughts building it up to make it seem like I was falling into a trap? Call me paranoid, but I was starting to fear the letters that once brought me joy.

I suck in a deep breath when the teacher tells us to partner up, grumbling under my breath. I wish I could just stay home and hole up in Irma's guestroom, away from crowds and prying eyes. Even now I can feel my hair stand on end from someone's staring, but this time, I could pinpoint it.

My eyes meet a swampy brown hazel, the staring boy's eyes narrowed behind thick half lens glasses. He glanced down at my rose and scoffs, clearly finding it in distaste. I frown, pulling the delicate flower closer to my chest. Despite my recent mixed feelings towards the letters, I still found the flowers precious. They were mine, and they were still fairly sweet. Even if this random guy disagreed.

I watch him look around at the quickly partnering students, a scowl on his face. He seemed to hate group projects too. Good. I hope he suffers. I turn away from him to see if anyone near me is also without a partner. Maybe if I get this done quickly, I wouldn't have to worry about any homework. I hate physics.

I scan the classroom, growing agitated as I realize the glaring kid and I were the only ones left. I slump back in my chair, meeting his glare. If he wanted a partner, he would have to come to my desk. I was not getting up for him.

He stands by his desk, face set in what seemed a permanent scowl. I couldn't help but notice his teeth, the front two being slightly bigger than normal. His black, fading, side buzzed hair was scruffy, small sprigs standing every which way. His purple satin jacket made him stand out the most, his posture too hunched for me to get a proper read on his height. I pull up a knee, staring him down. I wasn't going to back down, not for him. I didn't even know why.

It takes the teacher to scold us before he finally trudges over, obnoxiously tugging a desk over to meet mine. I watch his hissy fit with interest, hiding a smug smile behind my hand. I had won our little war, even if it was by accident.

"You better not be stupid." He hisses, his voice smoother than expected. There was a slight slur to his words, whether it was from a lisp or his teeth, I wasn't sure. I lean back in my seat, crossing my arms. I really didn't like him. "I will not be stuck with a stupid partner."

"You're in luck," I say tightly. "I happen to be pretty good at calculating a ball's trajectory."

The boy rolls his eyes, pulling out a notebook and flipping to a clean page. My eye twitches as I watch him. Even when he wasn't being annoying, he still got on my nerves. I pop my elbow when reaching down for my backpack, unzipping the top to search for my notebook. The letter falls to the floor and I ignore it for a moment, more focused on grabbing my supplies. My new partner's eyes focus on the fallen note, his sneer growing.
