Unable to leave you (Nagisa x reader)

Part 15

Back to your POV: "What are you talking about Koro Sensei?" I said as I come through the door way. "(y/n) you're okay" Nagisa said with a relief sound coming towards me trying to give me a hug. I quickly moved away from him and walked towards Isogai. "Nagisa....stop or else.... I'm going to leave you" I said coldly at Nagisa with out looking back. "W-w-what why?" Nagisa asked. I didn't answer him, I just stood up and walked to the doorway. "I...need some air" I said as I walked out.

"Why.......why.....why did he have to kill them..." I said as quietly as possible. Tears came down my cheek, I laid my forehead on my knees and started to cry.

Meanwhile while...
Nagisa POV: "N-no s-she didn't mean it, haha" I said trying to reassure myself. "Haha, she still likes me" I said as I started to walk towards Isogai. "This is your fault" I started to stab Isogai's corpes over and over again. "N-Nagisa stop Please" Yada said as she started to cry. I didn't listen to her. "You already killed Kayano why are you stabbing Isogai too? We also don't know what happened to Karma, Itona, and Terasaka" said Chiba. I stopped from stabbing Isogai. "They're all dead" I said. "W-what happened?" asked Okuda. "I killed them" I replied without looking at Okuda. "What?" Said Kimura. "I KILLED THEM OKAY?!?!?!" I shouted at everyone. "N-n-no..." Kanzaki Said as she started to cry. "What the hell man" Said Muramatsu.

Back to your POV: I got up and went back to the classroom. When I went in I saw Nagisa charge at me with with a knife.
