detective's partner {Jungkook ff}

-what if you really did-

 y/n POV

We are dating for almost a year now he texted me something earlier morning

"babe can I go to my friends house later?"
"sure no problem who is he btw can I be friends with him?"
"he? oh she's a girl my bestfriend since I was a kid her"
"oh nice what's her name"
"her name is Avalon Clenn Jones"
"can I see her pic"

he sends me her pic and just what I expected she's hot but I trust Jungkook so lets not go to conclusions but if something happens im done

"oh nice she looks nice"
"ikr many boys like her but she never accepted one"

*Ava calls Jungkook*

~dingdong dingdong someone's calling"~

I heard Jungkook's phone ring he answered immediately 

"hi Ava so when are you ready for game night?"
"sure is" Ava said

"oh you're going to pick her up"
"yes babe is there a problem?, Don't worry we have other friends that will come too"
"oh ok"

after we talk he said bye and so did I. I was worried and scared that something might happen but I trust Jungkook he never lies to me except when he eats my sandwich and say he didn't *laughs* 

after a few hours I decided to call and check on him

*ringringring* 

it took a few seconds before he answered I was wondering why he always answers quickly 

"yes babe, why?"
"wait why do you sound drunk?"
"come on its game ofc were going to drink"
"its ok just enjoy yourself just don't do anything bad ok!"
"I will not I promise"

it has been 5 hours since I called him I chatted him to see what he is doing

"babe are you still playing"
"yes babe and drinking a little bit"

I called him and when he answered I heard a bed bouncing and moving and I also heard some moans

"hi babe how're you doing are you alone"

and a random voice came in

"lets do it again" 

I heard a girl say that and I immediately hanged up

"guys what the hell?! I said to be quiet for a sec look what happen y/n is mad and she thinks im cheating damn it guys" *Jungkook says to his two friends whos having sEx*

He kept calling me again and again my phone kept on ringing again and again 

then I finally answered 

"how could you do this to me you said nothing will happen"
"no babe please let me talk its just a misunderstanding I would never do cheat on you"

I just hanged up on him 

 Jungkook's POV 

I barely slept cause of what happened I didn't go to her house yet because she still needs to cool down so I instead called her bestfriend Yuna to comfort her everything but I said to not tell that to y/n yet I wanted to be the one to tell the truth  

someone knocked on Ava's door 

*knock knock*

 "oh hi Yuna"
"Jungkook said you needed someone"
"oh that bitch"
"Why what happened?" she acted like she didn't know just like what Jungkook told her

y/n POV

we talked for a few hours but its already late at night so she already went home 
someone chatted me so I checked its Jungkook

"hey can we talk tomorrow?" Jungkook said
"why is there to talk about?"
"babe please just go to our fav cafe and ill explain everything lets meet exactly at 5:00pm"
