(authors note - THANK YALL FOR 100 VIEWS MUAH <3333)

Rengoku POV

I follow Giyuu to the rooftop and let him go first and I open the doors "Hello Giyuu~" Giyuu quickly turns his head to my voice I give a big grin to him "what'd I tell you when I gave you a warning" I pull a boxcutter from my pocket and run towards Giyuu he takes a stance and I grab him pushing him against the railing of the rooftop and he fights back grabbing my hand with the boxcutter we fight trying to push each other he punches me and I retract from him but I go to punch him but stab him in the stomach with the boxcutter his eyes widen and I push him over the ledge and look away when I look back to the railing I see his hand still holding on I look down to him "Your just making this more painful for yourself." I take the boxcutter and stab his hands a few times as his grip loosens and he finally lets go of the rail and I hear a loud splat with crunching below and right after a high pitch scream I quickly look down and notice y/n and run away "goddammit I thought they went home I hope they didn't see me"

y/n POV

You stay after school as you wanted to surprise Rengoku with ice cream you look around the school looking for him you go to the side of the school as you see a flash of a body dropping you realize it's Giyuu and you scream loud dropping your bag and you look up from where he fell and see a someone running away and catch a glimpse of red and yellow and you pull your phone out immediately and call the cops and soon they get there and question you of what happened and you tell them everything they tell you to go home and they would take care of it from there so you do and go to bed with an image od that in your head and end up having a nightmare. The next morning your very quiet and Rengoku is too and he finally asks "So did you get a good night's sleep?" you stay quiet for a second "no I didn't yesterday when I tried to find you after school I....I saw Giyuu fall from the rooftop" you look at Rengoku and his eyes widen and gives a sad look "Oh...I'm so sorry y/n" You look down "it's ok Rengoku" you both continue to walk to school in silence when you get to class you already hear all of the gossipings around the class that Giyuu had died and the police called it murder as you look confused you walk out of class to find an officer standing "hey uh what happened why are they calling it a murder.." the officer looks at you "I can't disclose that information" You give a desperate and sad look "Please he was my best friend since childhood please officer tell me!" He looks down and back up "we found stab wounds on the hand and stomach now go back to class" you slowly back away a bit shocked that someone here would kill Giyuu you think of the red and yellow hair and you think Rengoku but you think no..no it could never be Rengoku he would never..right? "are you ok y/n?" you jump looking to the sound and its Rengoku "ah...uh yea I am" Rengoku gives a smile "Alright that's good let's go back to class!" you both walk back to class together

Rengoku POV

I walk y/n back to class and I think about y/n acting a bit weird when I surprised them even now they looked so out of it don't tell me they knows something about what happened if they do I...I would have to- no let's not think about the worst here ok they probably didn't see me

(timeskiiiipppp)

Rengoku POV

What the hell is going on it's the end of the day and y/n has barely talked to me and it feels like they are ignoring me what's going on! This isn't normal at all I'm going to go insane if they don't talk to me I can't take this anymore I say my mind spiraling I watch y/n go to their locker and I grab their shoulder "y/n! why haven't you talked to me are you ok! they look up to me nervous "Please y/n just tell me what's wrong!"

"....did you kill Giyuu...."

(ooooo what will happen next!)
