There's a murder in the school! {A Markiplier x Reader fan fiction}

{Chapter 3} Poison

~Mark P.O.V~
I got a text as I was walking to school "Who could that be?" I mumbled as I took out my phone from my bag, I looked and it said 1 message from: Jack
~Text P.O.V~
Jack:You have a choice of weapons to pick in the music room
Mark: Ok
Jack: Also sometimes you might need to identify some people so take a picture and send it to me, then I can identify them, try and get a clear shot
Mark: I will try, but for now I need to get to class
Jack: Alright...
~(Y/n) P.O.V~
As the bell rang for lunch I knew I had to go to the rooftop, but I had to go to the bathroom so I walked out of class to the bathroom, Osana would probably be at the rooftop by now.
~Mark P.O.V~
I searched around in class 2-1 the teacher had also gone away for lunch and I noticed Osana forgot the bentos he had made for (Y/n) and himself, I had put on gloves and pick-pocketed the nurse while she was typing on her computer and opened her cabinet to the poison I don't even know why she had it but I took it, I knew which bento was for Osana and put in the poison and closed it. I quickly ran back to the nurse's office and put it in the cabinet I quickly shut it causing a loud "SLAM" and quickly ran to the boys bathroom, I took off the gloves and dumped them in the trash and gave out a heavy sigh "My first murder..." I silently said to myself, I washed my face off and walked out acting casual "Oh dear!" I heard the nurse say as he ran to the cabinet and I causally walked by, I quickly ran up the flights of stairs and finally made it to the rooftop, I snuck behind the wall to make sure I poisoned the right one "h-here B-Baka!" He said giving her the bento I had not poisoned "Thank god..." I muttered silently "Oh. This is what you invited me up here for?" She asked happily "y-yeah. But just eat it Baka!" He snapped "Thanks Osana!" She chirped they began to eat and a few bites later Osana began to cough...and cough...and cough he soon fell off the bench, inside I felt...joy? Happiness? But how?! I should feel bad and miserable and should've never done this! But inside deep down I felt happiness, joy and pure evil, but it all turned to a frown when (Y/n) screamed "OMG! OSANA! ARE YOU ALRIGHT!?" She shook his lifeless body, she quickly took out her phone from her bag and dialed a number "Hello? Yes my friend and I were just eating and he started coughing then he fell to the floor and he's not answering back to me!" She said tears threatening to fall, I couldn't watch anymore...it was like a living hell for me, so I left off to class and began to study.
