Angrily slamming the front door open, you entered your house.

Muttering colourful language, you swung your backpack across the house.

"Cupcake, I've told you not to throw things like- What happened?" your grandfather asked worriedly while getting up from the couch.

The corner of your forehead bleeding, your eyes red with anger.

"Nothing, chubs" you simply said while softening your eyes.

Only then you noticed the man sitting on the couch. You were so angry earlier, that you didn't even notice the black cars parked outside, and the man wearing a black tuxedo with turtleneck in your house even when you entered the house.

"I know you" you said. He seemed somewhat familiar.

"Of course you do" your grandfather snapped. "He's Jeon Jungkook" he said and your eyes slightly widened.

'He is-'

Your thoughts were cut off by Jungkook's words.

"Hi chipmunk" Jungkook said with a small smile.

"Kookie bunny" you said with mouth parted, not able to believe that it was really him.

"He saw you in the alleyway last night and found you familiar. So he approached me and see now, reunion!" your grandfather cheered.

You and Jungkook were childhood friends. He was three years older than you.

You studied in the same school as him, until your parents died when you were ten years old.

And then, you had to transfer to a new school as you moved in to your single grandfather's house.

Back then, you always knew that Jungkook was the heir of a powerful mafia family.

"Wait. Chubs, how do you know him-" your words were cut off by your grandfather.

"Haven't I told you that I used to supply paperclips to a mafia? It was Jungkook's grandfather" he said and you sighed.

"Wasn't that a joke?" you asked and your grandfather shook his head as a no.

"Aish! You're hurt. Come here now" your grandfather said and you pulled you by your wrist, making you sit beside Jungkook.

He walked to his room to get the first aid kit.

The room was silent for a few seconds until Jungkook broke it.

"Did you keep your promise?" he low-key asked and you nodded as a yes.

"Did you keep your promise too?" you asked back and he nodded proudly.

And what that promise was?

When you were five years old and Jungkook was an eight year old, it was a promise that you both would lose your first kiss to each other after growing up.

So, you both have not yet lost your first kiss yet.

"Are you a virgin?" you asked with no reason and Jungkook pouted while looking at you.

"I have not even lost my first kiss yet. Of course I'm a virgin" he said and your mouth performed an 'o'.

"Same pinch" you said while lightly pinching the back of his hand.

Jungkook smiled feeling your fingers on his hand.

Your grandfather returned back to the living room with the first aid kit.

Slowly, he started treating the wound on your forehead after wiping off the blood with a cotton ball.

His face holding a pout as it showcased his wrinkles.

"Please don't make that face" you said blankly and he huffed.

"Who was it?" your grandfather asked.

"Some guy that grocery store owner down the street sent" you simply said.

"Does that guy want a piece of me?" your grandfather asked, his face like the typical angry grandfathers, a bit funny.

"Haraboji, I've to make a call. I'll be back" Jungkook said and your grandfather nodded.

Yours wound got treated and a few minutes later, Jungkook came back to the living room and sat on his former position, beside you.

"I don't want a band-aid" you said with a not so impressed face while looking at the pokemon band-aid your grandfather was holding.

"Yah, don't be stubborn like a donkey" your grandfather snapped and your mouth parted in disbelief before you rolled your eyes.

Just then, Jungkook got a call.

"Oh, pookie" he said and looked at you. "I've to go now" he said.

"Ah, it's okay Jungkook-ah" your grandfather assured. "You can come back anytime you want" he said and Jungkook gave him his bunny smile.

"I'll accompany you outside" your grandfather added and Jungkook nodded.

Getting up, your grandfather started walking away.

Holding your chin softly, Jungkook kissed your left cheek.

"Bye" he said and smiled cutely as he got up.

"Bye" you said with eyes that were still widened slightly.

Chuckling, Jungkook placed another kiss on the tip of your nose before leaving.

Jungkook's pov

On reaching my house, I walked right away to the basement.

The two figures were tied up to the chair.

The owner of the grocery store, and the guy who was already in a pretty bad condition since Y/n beat him up.

My eyes turned dark while looking at them.

Grabbing a knife from one of the men, I walked towards the two.

In a swift movement, I cut the skin open on the guy's cheek and he screamed in pain.

Moving closer, I grabbed up his chin harshly, making him face me.

"No one dares to hurt my girl" I growled in a deep voice while my eyes darkened even more as i continued watching both of them who tried to hurt my Y/n, getting tortured mercilessly for hours.

Author's pov

Two days later~

As you were about to reach your house, you saw familiar black cars getting parked in the driveway.

You were in front of your house as Jungkook got out of the car.

"Hi pookie" he said with a smile. "Sorry I couldn't meet you for the last two days. I had some work and a mission completed just now" he said with a pout and you chuckled.

"It's okay, Kookie" you said while walking to the front door.

Unlocking the door, you entered along with Jungkook and saw your grandfather lying on the carpeted living room floor.

He does this often. Your grandfather says that it's more comfortable.

"Chubs, why are you sleeping on the floor again?" you asked while removing your backpack and placing it on the couch.

"Chubs" you called again, but your grandfather didn't respond.

Confused, you walked forward and knelt down beside him.

"Chubby cheeks" you said while shaking his shoulders but he didn't respond.

"Yah, what happened?" you said and shook his shoulders with more force this time, but he didn't even budge.

At the hospital~

"I'm sorry" the doctor said and your throat tightened.

It felt like the world around you was getting shattered into small pieces.

Your face turned blank as your eyes turned slightly misty.

Biting on your lower lip, you turned around and started to walk away.

"Ventricular fibrillation" the doctor said to Jungkook. "It causes death within a few minutes if left untreated" the doctor added.

A nurse entered walked towards the doctor and handed him the clipboard.

"Mr.Jeon, we need a relative to sign these papers. Are you related to him?" the doctor asked and Jungkook nodded.

"I'm his granddaughter's fiancé" Jungkook said.

"That will do" the doctor said and handed over the clipboard and Jungkook signed the hospital papers.

With the same cold look, Jungkook handed over the clipboard back to the doctor and ran for you in the direction you went earlier, worried for you.
