Regrets

(Y/N)'s POV
After the texts I sent I assumed he blocked me so I just shrugged it off and hurt Rantaro a bit I died a little inside watching him look at me in fear and hurting him I... I still love my brother but I only felt feeling around Kokichi and I just wanted to feel something I just sat on my bed till my legs wanted to move so I went downstairs when I saw Rantaro's face that made me upset it had cuts on it from earlier and his arms tiny slices when I saw what I had done I froze until he spoke
"Are you going to just stand there or stab me some more"
I stood there still
"Go on try to hurt me some more cause you didn't get what you want you little Psycho!"
He suddenly walked towards me and slapped me to the ground I just stayed still staring at him on the ground he hit me again
"What you're not going to try to kill me?"
"Huh"
"HUH?"
He hit me again 8 times until tears streamed down my face I still didn't feel anything don't get me wrong but my body just cried then I finally mustered the strength to speak
"I-I'm s-sorry. Please j-just hit m-me I-I deserve it!"
"Jeez stop stuttering it's annoying!"
And with that he hit me again I didn't care I just regret everything I did to him it was so brutal I wish I could just restart everything and kill myself but I'm too scared to kill myself I don't want to I just wish I could stop myself from being so aggressive he looked worried at me and called Kokichi over
"Oh my god! What happened?"
"She happened"
Kokichi walked over to me and kneeled down and hit me honestly this time I was really sad but I just cried I probably looked pathetic but I ultimately deserved it I reached up slightly and reached for Kokichi but he just slapped my hand down and snarled his nose
"I'm s-sorry for everything I've done to you"
"You're disgusting. Look at what you've done, you horrible child"
(Horrible kids would you look what you did. No one else thought of that? Just me?
Ok I'll leave ;w;)
"I know I've tortured you both and been super aggressive but I hope someday you'll forgive me."
"I will never forgive you, you should've never been born"
"Kokichi she's still my sister don't say that"
"Oh please she's a future murderer. And her first target is most likely you"
I got up and ran to my room to sit in the corner hugging my knees and crying (I do that a lot cause I'm emo haaah I'll stop making bad jokes now) I stayed in there for a while eventually I stopped and just kept hugging my knees for comfort then Rantaro came in after Kokichi left and sat next to me
"Hey. How are you doing?"
"Mm fine"
"You don't... seem fine. Is this a.... period thing?"
"Ugh NO!"
"Ok then what is it"
"I don't wanna talk honestly why do you still care about trash like me" (Komaeda is that you?)
"Because you're my sister and you're not trash"
Narrator POV
Suddenly you got that urge which wasn't good. You strangled him he passed out after a while but then. Then you did something you could NEVER take back. You dragged his body down to the living room, took a knife and sat over him. You hesitated for a second and then stabbed him in the chest. Repeated and repeated until there was a big hole in his chest. Blood all you could see was blood. You looked up then back down dropped the knife and got up. You gasped and covered your mouth with your hands and backed away then the door opened
"Hey Rantaro I forgot my-"
He stood there frozen in shock until he finally said something
"You monster! I'm calling the cops"
You decided this was it this was the time to end it all
"I"
"I don't care what you have to say you just murdered my boyfriend!"
"I'm going upstairs and when you see me again I won't be here I'm sorry Kokichi but this is it goodbye"
He didn't say anything he just ignored what you said and ran to Rantaro he picked up Rantaro's cold lifeless head and put it on his lap. Waterfalls were basically all over his face you wished you could take it back you went upstairs and told the rope and tied it into a noose hug it on your ceiling fan put a stool under it and stood on the stool put the rope on your neck and kicked the stool immediately you started choking and it hurt a lot but it eventually stopped and the world around you faded you were dead.

Kokichi's POV
"Why. Why did this have to happen. Why (Y/N). WHY!? It's just not fair he didn't deserve this no one did"
If he could say something he'd probably say something like you kinda left her hanging there
I carefully set Rantaro's Head back down gently kissed his forehead it was so cold and got up to confront (Y/N) as I went upstairs I figured she could be asleep. Waking her up in her own house sounds like something a boyfriend would do. I gently open the door "(Y/N)" I saw her dead body she was hanging on a noose I wanted to throw up (credit to ddlc) I just screamed and then I heard the sirens thank goodness the cops are here and my clothes are clean I ran downstairs and opened the door looking petrified
"Sir what happened"
"My boyfriend and his sister they ngh please. help. I"
"Sir calm down"
"Please just look for your self then go upstairs first room on the right"
They went inside I ran out crying they came out after investigating and started to question me
"Sir can you explain what happened"
"Yes well my boyfriend's sister (Y/N) met me and soon after started stalking me and then she was aggressive towards her brother and said I was hers she ended up in an asylum for trying to strangle him but she was released and she eventually tried to kill him but I stopped her and this morning she shut down and cried then I left but when I came back he was... dead ...and she was shaking her clothes were bloody and she had her hands over her mouth."
"Ok sir then what"
"Then she said something about ending it all apologized and said the next time I see her she won't be here when I went upstairs later she was hanging there"
"Ok thank you sir"

The end

Thanks so much for reading this it wasn't very good and I didn't want to finish it but I finally did I'm so sorry it was over dramatic and intense I promise I won't write something like this again I'm sorry for those who liked it but writing this was just to much for me so I won't write one like this but I may sometime when I'm less depressed and can handle this dark stuff but for now I'll write nicer fanfics thank you
