Rengoku looks a bit out of it when he says "What are you talking about of course I didn't kill him why would I-I have no motive to" You think a bit and say "Well...could it have been you were jealous he would flirt with me...and when he came to lunch with that big bruise on his cheek that was you wasn't!?" Rengoku looked as if he is spiraling not knowing what to say next "wha- what..." he holds his face in his hands you back up a bit when you hear him giggling a bit as your heartbeat gets faster he smiles and removes his hands he looks psychotic "R-rengoku" he pulls something from his pocket "tisk tisk I knew this was going to happen I just didn't think so soon such a shame....will you be mine" he grins "what no you're a psycho you killed someone!" He looks disappointed "aw I didn't want it to be like this oh well" he swings the knife towards you and you back away as your eyes fill with tears your cheek slit a bit feeling blood dribble down and you run away down the hallway of the school its a bit dark "y/n get back here you can run as much as you want but you won't get away!" You continue down the dark halls and you slide on one of the floors and you slowly crawl into one of the classrooms and hide in the corner and you try not to cry out loud and you hear "y/n y/n come outttt~" you hear a door slam open and you flinch "aww not in here" you grip your knees hoping he would just give up but you hear more doors open and you can hear his footsteps get closer and closer to the classroom your hiding in and you whimper a bit he looks into the room your in and opens it "ahh y/n there you are" you scream and you crawl a bit away from him and cry out "p-please...Rengoku I beg you to let me go...I won't tell anybody" your back hits the wall and you try to get up towards the door Rengoku slowly walks too you "I love you y/n" Rengoku grabs you by the shirt and you whimper and cry as he kisses you and puts his hand onyour cheek "if I can't have you no one can~" He stabs you in the stomach and takes the knife back out and drops you on the ground and he rubs your cheek as he looks you in your eyes as you start to bleed out your life flashes before you and you think of all the times you and rengoku spent together and your family your friends as you can feel yourself start to slip away and your whole body goes numb and your heartbeat gets slower and Rengoku watches your soul slip away from your eyes until finally your heart stops

Rengoku POV

I stand up from their body and look down at them "I'll miss you y/n don't worry we'll be together soon" I smile and take the knife and point it towards myself and close my eyes and I stab my throat my eyes open I take the knife out and I bleed out hearing me choking and gurgling on own my blood and I drop to my knees I slip away from my body and fall onto y/n's body
