~Killua's POV~
I watched in horror as (Y/n) had stabbed Gon and then ran away. I heard screams but it wasn't (Y/n)s.
I ran to Gon's side as he was clutching his chest in pain.
"We need to get to the hospital" I said.
"No..." Gon said "I'm... n-not leav... ing without... (Y/n)"
"...I understand"
"...I'm not l-letting... (Y/n) out of my... sight again"
Gon started to cough up blood and I panicked. I looked around the room and saw a medical kit so I ran to it and picked it up.
"I'm not good at stuff like this but I'll try to sew you up"
I walked back over to Gon and started sewing.
~Time skip~
Looks like I did a good job.
"...Let's get (Y/n)" Gon said and I nodded.
~Gon's POV~
"Why did (Y/n) stab me? It probably wasn't her fault. Maybe she was brainwashed"
We left the room and I saw blood all over the walls and bodies laid on the ground.
Me and Killua followed the path and we eventually caught up with whatever was killing all these people.
It was (Y/n). It broke my heart to see the person I love killing.
I ran towards her and Killua was yelling something to me but I didn't bother to listen because all I cared about was getting (Y/n) back.
I hugged her from behind and cried into her back.
"(Y/n) what are you doing? Please stop... I love you so much" I said "I can't bare to see you like this"
(Y/n) felt light in my arms all of a sudden and she fell unconscious.
I went outside with (Y/n) in my arms beside Killua.
In the distance I saw a figure approach.
"...(Y/n)!" they said, running towards me. I recognized them, it was that guy from earlier, his name was... Armin? He had a concerned look on his face.
"Is she okay?!" He asked crying.
"I hope so. Who're you?" I asked
"Armin, what about you?"
"Gon"
"How do you know (Y/n)?"
"She's my girlfriend"
"O-Oh..."
"How do you know her?"
"She was my past girlfriend"
"...R-Right..."
(Y/n)'s face was pale. I just hope she's ok.
