Freedom

After a few more days I was let out I was so happy until Kokichi came over to hang out with Rantaro I hated every time this happened I sat in the kitchen and watched from afar the counter and the cabinets made it hard for them to see me so I was ok but I got and urge it took over my body and I tried to stop it but I couldn't so as they watched a movie with the lights off and blue light from the tv reflecting on me I walked over and grabbed a rope and walked up behind Rantaro and strangled him Kokichi let out a shriek and ended up tackling me
"What are you doing!?"
"Hahahaha ahahahaha don't you get it? I'm psychotic. Every little part of me hates him. You're mine so stay away from him ok I promise I won't hurt him if you just stay away from him."
"Please stop" he begged but I didn't. He had to be mine. He must be mine.
"I can't, not when HE'S taking you away from me he's brainwashing you to dislike me I swear!"
"He's not brainwashing me just go away and leave him alone!"
So I went back to the kitchen to continue stalking him and when the time came Kokichi went home and Rantaro went upstairs I waited a while and left I followed him home and memorized his address and mailbox number the next day we went to school and as if nothing happened everything was normal at school Kokichi would pull a prank I'd take credit and later go home and watch them after he left I thought of something what if I threatened Rantaro and forced Kokichi to date me that way? So I knocked out Rantaro and tied his arms and legs to a chair and put a gag in his mouth and while he was knocked out I took some of his blood I didn't patch it up leaving him to bleed and put the blood in a small capsule like container then wrote a letter saying your precious Rantaro is here and he's alright but not for long if you care about him break up with him and so I went to Kokichi's neighborhood and put the letter and Rantaro's blood his mailbox and ran home then I saw Rantaro still bleeding and passed out I moved him to the basement and put a rag on his still-bleeding arm and soaked up the blood with that once it finished you put a bandage on it and left him there you heard muffled sounds coming from the basement so you went down "oh you're awake finally it took you long enough"
"Where am I what's going on?"
"Well I knocked you out and now this happened"
"You sick"
"Psycho creep sadist maybe. I don't care though"
You heard the front door burst open as if on cue
"Huh that must be Kokichi."
"What'd you tell him"
"That you're in danger when you're really not at all"
"Why"
"Because you have what's rightfully mine and I WANT IT BACK"
"He was never yours in the first place"
"Shut up. I'm going upstairs have fun squirming but it won't do anything"
And with that I went upstairs "(Y/N)! You Psycho where is he!"
"Basement"
Luckily the basement was underground so there was no escape as you went Down there with Kokichi and watched as he untied him and removed the gag, you went up and locked them in there from the outside soon enough you heard running and they started banging on the door
"HEY (Y/N) LET US OUT!"
"Not until you stop dating and admit you love me"
"Why?"
"Because Kokichi you're mine you don't have a choice! You never did from the start!"
You could hear him crying which made you angry so you got a rag of chloroform and opened the door you let rantaro run out and grabbed Kokichi by the collar of his shirt and put the rag over his mouth he squirmed a bit but then passed out you carried him like a princess and went to your room and locked the door and went downstairs
"WHERE'S KOKICHI WHAT DID YOU DO TO HIM"
"Nothing I told you I would never hurt him he's safe now that you're away from him!"

Kokichi's POV
Finally (Y/N) let us out of the basement but she grabbed me and I smelled something weird and everything went black when I woke up I was on a bed with (favorite color) sheets and (2nd favorite color) walls I could only assume it was (Y/N)'s room but I realized she locked me here. The door is locked from the inside so I could escape but
(Y/N) would probably catch me so I opened a window and jumped I went to my house and texted Rantaro
"Hey I'm back at home I'm ok"
"Good I'm calling the asylum first thing in the morning"
And then I got a text from an unknown number
"Why'd you escape? Things were much more fun with you here!"
"Because you're crazy"
"Oh well I guess I'll just kill Rantaro then"
"NO DON'T!"
"Then date me"
"Why? Why can't you just accept that I don't love you"
"Because you will"
"I will never ever love you"
"Then I guess rantaro will die"
"Stop threatening him"
"Why?"
"Because he has nothing to do with this"
"HE HAS EVERYTHING TO DO WITH THIS"
"If it matters that much then we'll break up just don't hurt him"
"Hahahahahaha"
"What"
"It doesn't matter if you're together or not you still love him either way"
"No... I won't"
"Yes you will so I'll still have to kill him"
"Why why why why why"
"Because you belong to me"
I stopped texting her and texted Rantaro
"Hey your crazy sister is texting me"
"What how'd she even"
"Idk but I'm going to sleep"
She still continued to text me so I ignored it and slept.
By morning I had 200 texts from her.
so
I blocked her
