Lia...an 18 year old college girl never once thought of anything else other than passing college, Getting her dream job and living her life without any interruptions...But love is known to surprise those who want nothing to do with it...She meets a shy boy,17 years old,just graduated from high school and just starting on the same college Lia's currently studying at. Through first glance,She felt a thump in her heart when she him...his soft gaze...his slightly messy but soft hair...his innocent shy smile and laugh... Everything about him drawed her closer to him and it would be a lie to say that he wasn't attracted to her too. One thing lead to another and the two got together,the most happy both have ever been...until a misunderstanding...a mistake happens...forcing one to kill... regretting it greatly after learning the truth and slowly slipping into a great demented mind to where they want nothing more than to be in the arms of their loved one...if only they had listened and believed...but that's the other thing about love...It also kills...

A few days after discovering the truth,a young female adult was running back home, panting heavily while quickly and desperately clawing to get the floor boards to open.

???: Shit shit shit!!! Come on!! Open!! Y-you can't be dead already!! N-not after I just learned T-the truth!! Y-you better still be alive!!!

(The floor boards finally gave out as she tore them off, reaching down and gently picking up a young teenage boy out...with multiple stab wounds on his body,the young adult gently set the body down with his head on her lap,not caring about the blood on her lap)

???: Come on (Y/n),you can't really be dead...I-i didn't really kill you...c-come on...wake up...

(No response was heard,she started to get scared)

???: O-okay okay...! I'm sorry...I'm sorry for not believing you... I-i'll do you any favor you want...now come on... open those sexy eyes of yours...hey...come on...stop playing...t-this isn't the time for your jokes...wake up...

(Again,no response,the young adult's heart began to hurt as their brain couldn't believe that their lover... their shy, innocent,loyal lover was dead...and it was all their fault...)

???:C-come on babe...y-you know I-I didn't mean it... P-please wake up...
(The person softly shook the body...no response was heard) P-please...I-I didn't mean it... I-I'm sorry...I-I should've believed you... n-not them... wake up...wake up... P-PLEASE WAKE UP!! I-I'LL NEVER DOUBT YOU AGAIN!! I-I'LL BELIEVE EVERY WORD YOU SAY!! I'LL DO ANYTHING YOU WANT I-I PROMISE!! JUST PLEASE!! PLEASE GET UP!! Y-YOU CAN'T DIE!! PLEASE!!!

(No response...the person slowly took ahold of their own hair,fear,regret,shame and sadness overwhelmed them...)

???:No... p-please don't do this...D-don't go...i-i didn't mean it... P-please don't go...o-open your eyes...stop playing...D-don't joke around...open them... p-please... i-i'll never believe in anything else u-unless you want me too... I-i'll keep you safe a-and loved...I won't let anything trick me into hurting you again i-i swear...j-just please...don't die... don't leave me here...

(Once again...no response...the person's eyes slowly turned dull as her mind shattered...she looked at her hands...their lover's blood coating them,they stared at their own hands in disgust...then a laughter was heard,soft at first...but it grew louder...it erupted into a full blown laugh of insanity...)

???:hehehehehe....hahahaha....HAHAHAHAHAHA!!!! HAHAHAHAHAHA!!!! I-IT WAS ALL THEIR FAULT!! THEY DID THIS!!! I WAS A FUCKING IDIOT FOR BELIEVING THE WORDS OF LIARS INSTEAD OF THE VOICE OF MY BABY... DON'T WORRY BABE...YOUR BELOVED WIFE'S LEARNED HER LESSON... EVERYONE'S JUST A LIAR... EVERYONE EXCEPT YOU...YOU NEVER LIED TO ME...NEVER ONCE DOUBTED ME... ALWAYS BEING THERE WHEN LIFE DECIDED TO FUCK WITH ME...HEHEHE... IT'LL BE OKAY...I-IF TALKING WITH THOSE FUCKERS MADE ME KILL YOU... THEN KILLING THEM WILL BRING YOU BACK...BACK IN MY ARMS AGAIN... WHERE I CAN KEEP YOU SAFE...LOVE YOU AND NEVER LET ANY FUCKING THING GET NEAR YOU... THAT SOUNDS GOOD, RIGHT BABY?

(The bloody corpse said nothing,but the now broken person merely giggled insanely as they walked to the corpse, knelt down, embracing it, giving the corpse a gentle kiss on the lips)

???:I promise... They'll pay for making me doubt and stop loving you...and this time... I'm keeping that promise...along with Bringing back ours...handsome~ Wait for me...just a little bit... I'll get you back again...and when I do... nothing...will ever get to me again...no lies...no doubts...no traitors... it'll be only us..just you...and me...

(The person softly picked up their dead lover as they took them to their shared room, memories of their time together in this very room filled the person's mind,further breaking them with sadness and the unbearable want of wanting to experience that again with their one True love)

???: Don't worry my darling... I'll be better...a better girlfriend...when you come back... we'll spend every second together... whatever you want, it's yours... I'll keep you safe from everything in this fucking world...it can hurt me all it wants...but I won't let it hurt you... nothing...will ever hurt you again...

(The person softly laid the body of their lover on their bed,not caring if blood would deep into the sheets,they softly laid next to them, wrapping their arms around the corpse's waist,pulling them closer with tears escaping their eyes...the moon softly shined down on them...an 18 year old bad girl...and a 17 year old dead boy...)

???:Baby... I'm going...to bring you back...I don't give a fuck how long it takes...I don't give a fuck how painful it'll be...and I especially don't give a fuck who gets in my way... I'll do whatever it takes...

You're mine (Y/n) (L/n)...And soon...the world will know what happens...when they make me hurt...the only one who loved me fully...I will bring you back...no matter what...
