Author note: this is my first ever fanfic so its most likely going to suck and make absolutely no sense, enjoy
As you head into the classroom you see Nagisa staring at you. You question in your head why is he staring at you, since normally when you walk into the classroom he's always talking to Karma and Kayano. As you wonder, Karma suddenly walked over to you and kissed you on the lips. From that kiss you jolted and pushed him away while wiping your lips with your sleeve. "Karma...why did you kiss her" said Nagisa in a threatening tone. "Why can't I? After all she's not yours" Karma replied. As you look up you see Nagisa and Karma staring each other down with death glares. "Ok Karma, Nagisa go to your seats it's time for class" said Koro Sensei.
When lunch rolled in you see Nagisa looking at you. "Hey...Nagisa can I ask you a question?" you asked him while being really nervous. "Sure (y/n)" Nagisa replies. You gulped for a second unsure what is reply would be. "Um...why were you-" you couldn't finish your sentence because Karma started to lick your neck. "THATS IT KARMA, YOUR GOING TO DIE" yelled Nagisa. Karma stopped, but instead of looking at Nagisa he just left his eyes on my neck. "Oh? And how are you going to do that?" Karma said as he started to smirk. "By using THIS!" Nagisa yelled leaping at Karma quickly pulling out a real knife.
