Best friend to boyfriend?(short jungkook fanfic)

Backstage

I was sitting on a chair watching BTS getting ready for their concert .... Well at least some of them ,some were more like messing around .

All of a sudden I heard someone laughing and I went to find it who it was and jungkook with and girl
It seem that she also have a backstage pass

She look like a girl that can do an aegyo because she is so cute

"Oh hi Nami " said jungkook

" hi jungkook "I replied

"Oh sorry I need to introduce myself " said the girl

"Hi my name is sunhi and I'm jungkook girlfriend "

I was shock when I heard that and I was about to cry because I also have feelings for him

"Nice to meet you and take care of jungkook " was all I could say

And then I went to the bathroom and dry my tears away when my tears was gone I went back to bangtan dressing room

"Nami what's wrong it look like you've cry " asked V

" oh it does " I questioned

"I went to the bathroom and when I washed my hands I was moving it roughly so the soup got into my eye " I lied

"Your up in 10 minutes BTS so hurry"a woman said

They were already ready so they can do anything for 10 minutes

They were doing their personal thing and jungkook was still talking to his " girlfriend  somewhere

*jungkook POV*
I saw a girl who kinda looks lost so I went to her and it was my use to be crush sunhi

"Hello jungkook my boyfriend " sunhi said

"Do you miss me ?"sunhi asked

" of course not "I replied

"Well that sucks I really like you now " she said

Sunhi is a girl I had a crush on when I was younger I asked her out but she rejected me

She is a cute girl who can do aegyo pretty well

Now I don't have feelings for her anymore

All she want is popularity she came back to me because I'm now an idol

Hahah that stupid girl she thinks I don't know her secret

I hate to admit it but when I was younger I use to stalk her

"And now I take back what I said years ago you can be my boyfriend " she said

" like hell anyone would still want to be your boyfriend now I have feelings for someone else "I replied

She said " of course you do " and started laughing

*nami walks in *

"Oh Hi Nami " I said

" hi jungkook " she said

She was looking at confused

"sorry I forgot to introduce myself " said sunhi " hi I'm sunhi and I'm jungkook girlfriend

That stupid girl why did she say that

All she said was " nice to meet you and take care of jungkook " and it look like she was tearing up when she ran out I couldn't stop her because sunhi was holding my arm

"You stupid girl why would you do that " I yelled at her

" why would you say that to your girlfriend " she said it in a joking way
" dream on because your not my girlfriend " i said

"Let go of me u b*tch " I said kind of in a yell

And then I went to look for Nami

Sunhi POV

I won't let you go
This is perfect opportunity to gain popularity
Just you wait jungkook I will make you fall for me again and that girl won't stand in my way

End of all POV

I was just waiting like all the other BTS members is and then it was time to start their concert

Sunhi came up to me and asked
" what is the relationship between you and jungkook huh ?"

" just so you know he is mine and I'll do anything for it even kill you " she warned and walk away

Why does jungkook like a girl like this ? I questioned myself

*at the end of the concert *

When the concert is over they came back to their dressing room

Jungkook greet me with a warm smile and glance at sunhi

After that we decided to have a party because BTS did well on their concert

" will you be joining us " jungkook asked me with a warm smile

" I don't know " I replied
" oh please " he pleased

" okay fine " I said giving up by his aegyo

" can I tag along kookie " ask sunhi while doing a aegyo

" no " and such a person like you are not allowed to call me by that nickname " I replied

" oh please let me tag along " she pleased

" she is so cute why won't you just let her tag along "asked asked jimin
because he doesn't know their past and the other do

" you got no jams " said rapmon

"Anyway let's go home and party " said V waving  his arms around like just don't care
