Promise: Jungkook FF

"Kook?" Jimin asked.

Both of you froze and started to get nervous.

"Y-yes, hyung?" Jungkook asked stuttering.

"Who are you talking to? Why did I heard about marriage and mafias?" Jimin asked.

"Umm... I was just... ummm... joking. It's not serious." Jungkook said.

"Then who is it? You didn't answer my first question." Jimin said.

"I-it's my friend." Jungkook.

"Friend? When did you had another friend? And talk about marriage? Jungkook, I clearly heard what you said." Jimin said as he glare at jungkook.

Jungkook kept silent, because he didn't know what to say.

"Wait... did you just move on so quickly and found another girl?!" Jimin shouted with anger.

"What?! No, hyung!" Jungkook said.

"Are you cheating on y/n this whole time? Is this the reason why she broke up with you?" Jimin asked.

"Hyung, whatever you say, y/n is the perfect woman for me. And I'll never cheat on her." Jungkook said.

"Prove it." Jimin said.

"We broke up because something huge came up. I can't tell you, because it's dangerous. And this is my fight, at least this time, I can solve my problems on my own. I never cheated on y/n, because I can't. If we didn't broke up, I will probably fly back to korea just to feel her in my arms again. Hyung, I miss her, I miss her hugs, kisses, her voice. And to see her again, I should do this alone, so please, KNOCK BEFORE YOU GO IN!" Jungkook said.

You laughed, but bot too loud.

"Okay... but I hope that you'll solve that problem fast. Because I can't let my ship sink." Jimin said with a smile before he left the room.

When he leaves, jungkook sighs.

"Good thing that hyung didn't heard it all." Jungkook said.

"Be careful next time! Aish... or next time, I will not answer your calls." You said.

"I'm sorry... I didn't know." Jungkook said.

"When is the 'FAKE' Wedding???" Jungkook said.

"Next week... on... y-your birthday." You said hesitating.

"That jerk! I probably think that he really planned it! If only I could kill him!" Jungkook shouted in anger.

"Easy! Someone might heard you!" You said.

"Sorry..." Jungkook said.

"Don't worry about it bunny... My gift for you is to put him in jail forever." You said.

"Make sure that it will come true... Because I want that gift so badly." Jungkook said.

"I will start training tomorrow, so I may not receive any calls, but I promise to call you when I can." You said.

"Okay, just don't forget to take care of yourself. Bye, bunny~ Our next and last performance is next, I need to prepare." Jungkook said.

"Bye~ I love you~" You said.

"I love you more, Y/n Anderson." He whispered through the phone.

You chuckled and both of you hung up. And you sigh.

"Jungkook relieves my stress... I didn't even noticed that I started smiling and laughing when I was angry in the first place." You said and smiled.

You start the engine and drove home. When you arrive, you change your clothes and fell asleep.

Next morning~

You woke up by the alarm. You got up and go straight to the bathroom to take a bath. When you finished taking a bath, someone called you. It was your friend, Ae-cha, so you answer it.

"Hello, Ae-cha~" You said.

"Hi y/n! Ready for the training today?" She asked.

"I was born ready." You said.

"That's my girl. I'll pick you up by 5." She said.

"Okay..." You said.

Then both of you hung up. You wear your gym clothes and while waiting, you text jungkook.

*In the text*

You : Good morning, bunny~

You : I'm on my way to my training... I know you're sleeping, but I just want to inform you so you're not going to be worried☺️

You heard the car outside, so you get your bag and walk out. When you got inside the car, you got a message.

*In the text*

Jungkook : Okay, bunny... be careful~

You smiled through the text. Then you go inside the car.

"Y/n... you know that jayson was smart too, right?" Ae-cha said.

"I know, but what do you mean?" You asked.

"One day ago, you told me about your plan, but did you know that he might be using your phone to track or spy on you?" She asked.

"Yup..." You said.

"Then why are you still using that phone?! You called me and told everything about your plan... USING THAT GODD*MN PHONE!" She shouted.

"Haven't you noticed it yet? That this is part of the plan. The plan that I told you was the fake one, you know that dad trained me before, and that's when I knew about that jerk. Even though I'm not a mafia, I know how they work." You said.

"Wah... daebak... you're full of surprises, y/n." She said amazed.

"I always use my brain..." You said.

"Aigoo... then am I still going to train you?" She asked.

"Of course, your part was the real one." You said laughing.

"You should've keep it as a secret! Stupid!" She said.

"Watch your words, young lady. The reason why I let him know about the training was because I want him to know that I'm weak. I won't start training if I'm already strong. So... he will thought that I can't fight him after my 1 week training." You said.

"But are you sure that he's tracking and spying on you? I mean, the plan was perfect." She said.

"No, it's not perfect. And yes, I'm sure. You knew about my anti-virus app? It's also tells me that someone is tracking or spying on me." You said.

"The app you made?! Wow... You're not just smart! You're a genius! Smarter than einstein!" She said.

"I'm not a genius... I didn't invent something... unique ." You said.

"Y/n... smart isn't about inventions." She said.

"I know... but genius is not the right word for me, ya know." You said.

"Wah... many people wanted to be called genius, but you, you don't even care about it, you even hate it!" She said.

You something on the wing mirror of the car, you've noticed that a black car has been following the two of you.

"Ae-cha, can you drive faster? I mean, just turn up the speed for like a minute." You said.

She followed you and the black car also fasten its speed. You sigh.

"What is it, y/n?" She asked worried.

"A car is following us. Let's change seats. I'll drive." You said.

"But y/n! We need to stop first! It's dangerous!" She shouted.

"I'll turn off the car lights and hold the wheel. While it's dark, we will change seats, got it?" You said ignoring her.

"No! I don't want to risk my life!" She shouted.

"Ae-cha! Listen to me! Those people who's following us are dangerous! So if you want to save your life, do what I say!" You shouted.

She paused and nodded. You turn of the lights and hold the wheel. She started to go to the passenger seat and you go to the driver's seat. Then you turn on the lights again. The mens who was following you where confused about the light, but when it turned on again, they thought it was just an accident. Ae-cha was nervous and scared, you can feel it. She was breathing heavily.

"Ae-cha... listen... I'll drive faster, so don't be scared. I'm here, I can protect you. Close your eyes and use my airpods to listen to some relaxing music. Ignore what's happening and focus to the music. I'll remove one airpod when we're safe. Understood?" You said.

She nodded and put the airpods on. You chose the music for her and she was closing her eyes. You took a deep breath and started to drive faster. The black car was still following you. You saw a U-turn and quickly turn the car. The man who was driving in the black car got surprised and didn't followed you because of the speed. You remembered about the phone, you open the window and throw it in a vacant lot. You smirked and drove faster until you saw a street that you can hide, since there was 3 different streets and you chose the left one. You can't see the black car.

"I guess they can't track me." You said.

You remove the airpod on her ear. Then she quickly hug you.

"Thank you, y/n... I thought that I was going to die." She said.

"Listen... you're not safe... so I'll leave... don't contact me, don't go near me, and report to police about what happened. Just say that you didn't know who was following us. Please... follow what I said, this for your own good." You said.

"Y/n... I can report what happened, but I can protect myself. As your best friend, I should be there for you." She said.

"Ae-cha... I don't want any of my friends and family to be in danger because of me. And you just got in danger right now. So please... just... stay away from me for a few days. This won't last long." You said.

"No! I know I got scared earlier. But I won't be scared next time! Y/n, you said it! You didn't want others to be in danger, so do I! My friend was enduring to much pain and problems, her life was in danger. So I should be helping her right?!" She shouted.

Your tears started to fall.

"Ae-cha! Stop being stubborn for at least once! I understand that you can't leave me... but it's just for a few days. Jayson was a dangerous man... if he want to kill right now, he will. And I don't want that to happen." You said while crying.

"What about your plan? Didn't I need to help you?" She asked and also crying.

"Yes, but... I'll think a much more better plan. That I can do on my own." You said.

"No... please y/n... what if something happened to you? What if... he will kill you?" She asked.

"No, he won't... because he's obsessed with me." You said.

"What?" She asked.

"Jayson got obsessed with me even if we hadn't met. And he can't hurt me... yet. So I'll give you jungkook's number to tell him about what I told you. Please... do everything you can to make him believe you." You said.

"What if... he still didn't believe me?" She asked.

You get her phone. And started to voice record. Then you finished recording and fell into tears. Ae-cha comforts you.

"Please give this to jungkook... and guard him, because I know that jayson has plan." You said.

She nodded and hug you for one last time, and you leave. Her heart aches while she was staring at you running away. She planned to go to jungkook and get an backstage pass to meet him. She wanted to make sure that he will listen to it.

Meanwhile, jungkook has been calling your phone and contacting you, but you're not answering. He thought that you were still in training, so he ignore it. Few hours later, the concert starts. He can't stop thinking about you. He was so worried.

"She must be finished by now... but why she's not answering?" He said to himself.

Then the concert was finished. BTS was saying goodbye to their fans, while jungkook hasn't talk even a word yet. His hyungs noticed it and asked in front of the armys.

"Kook? Are you okay? We're getting worried, because you look so down since morning." Jin asked.

"Ah... umm... yes... I'm fine... I was just stressed and tired." Jungkook said.

"Jungkook, we've known you for 6 years now. and we know that there's something wrong. Tell us... us and the armys are here to comfort you." Namjoon said.

"Is it about the break up?" Hoseok asked.

"N-no... so let's not waste the time with the armys." He said and smiled.

They know that it was fake. Ae-cha noticed jungkook the whole time... she was sad for the both of you, because it is hard to start a relationship like this. The two of you just started, yet, fate was already testing the both of you. It's time to meet them, when she met them, she was just acting normal. But she didn't even took any pictures or did any skinsh.i.p.s with the boys, because she's focused to what she was planned to do. Then it was time to leave, the fans who was with her leaves, but she was still sitting there.

"Miss? It's time to leave. We still need to prepare to go home." Namjoon said.

She stands up and get her phone. They thought that she wanted a picture, but she asked something.

"Can you all leave? I need to talk to jungkook privately." She said.

"Miss... we can't do that." Yoongi said.

"Please... I'm begging you... it's about y/n." She said.

"How we be so sure that you're telling the truth?" Jungkook asked.

"My name is ae-cha... I'm y/n's friend. And she just want to tell you something, jungkook. I'm not planning to do anything bad." She said.

"We will order the staffs to leave. But we need to there for jungkook." Jimin said.

"It's okay..." She said.

The staffs leaves and she took a deep breath.

"So what is it?" Taehyung asked with a cold tone.

"Y/n was in danger... a black car was following us earlier this morning." She said.

"What?" Taehyung said.

"You were her friend that she was talking about?" Jungkook asked.

"Yes, she told you that she was going to training with me today. But someone followed us, y/n noticed them and we changed seats so she can drive. We get escaped. But I think there was something happening, because she wants me and other people to stay away from her." She said.

"We don't believe you..." Jin said with an angry tone.

"But I'm telling the truth..." She said.

"Jungkook! Did you know all about this?!" Namjoon shouted at jungkook.

"Hyung..." Jungkook said.

"Kook! Answer us! Is there something that we didn't know?! Why did the two of you talked to each other this morning?!" Yoongi shouted.

"Boys, don't get angry at jungkook. Yes, y/n and him was hiding something. But instead of shouting at him, comfort him, because he might be in pain." Ae-cha said.

Jungkook told them everything and the boys were shocked to know the truth.

"... but I didn't know anything about what happened today... I was calling her, but she was not answering." Jungkook said.

"Because she thrown her phone away." Ae-cha said.

"What?" The boys asked.

"I guess this voice record can explain everything." Ae-cha said.

She open her phone and tap on the voice record.

"Bunny... this is y/n... please believe to ae-cha, she's my friend. She's telling the truth, so... don't contact me or find me. Please..." You paused and sobs.

"I don't want you to be in danger. Jayson is a crazy man... I don't him to kill you. He knew that we didn't broke up, because he was controlling my phone. I changed the plan... and this time, no one will help me. I can do it on my own. Please endure the pain for a few days... for me. I promise that I'll come back and see you. You can tell the boys, but ONLY the boys. Don't tell it to the public, because jayson might kill me if that happens. Wait for me... I love you so much, jeon jungkook." You said.

They finished listening to it and started crying, especially jungkook.

"I love you more, y/n anderson." Jungkook said and sobs.

"Y/n said that I should guard you. Because jayson might be planning something to you. I know how to fight, so she trusted me." Ae-cha said.

But they ignore her and continued crying. Jungkook can't accept that you'll be away.

"I can't even protect her... what kind of boyfriend am I?" Jungkook said to himself while crying.

"What if something happened to her? I'm not there to save her." Jungkook said.

"Jungkook... y/n is a strong girl... don't think things like that." Namjoon said.

Their manager heard everything. And it also hurts him to see the boys hurt. He prevented the staffs to hear anything inside until they were done. Ae-cha came out and the staffs saw her tears in her cheeks.

"Why did that fans came out crying? " One staff asked.

Their manager came in and saw the boys. He was shocked to see their eyes swollen from crying and tears in their cheeks. He didn't saw the boys cried this much.

"I heard what happened... so what are you going to do? Cry all day? Be lazy and sad during performance? Boys... you can't just stay like this! I admit... I don't know what kind of girl y/n is... but did you know that all of you looks so weak right now? You have each other and she's alone. You can fight together and she's alone. But you're weak and she's strong? You already said it... y/n is strong... then at least act and try to be strong for her! You're hurt that she's away? That you can't see her? Did you think of what she also feel? If she saw you like this, she will be disappointed. Can you do anything for her?" The manager said and a tear coming out of his eyes.

"Then let me ask you back, manager-nim... Is there something we can do for her? To help her?" Jungkook asked.

"Yes... to be strong and prepare for her to come back." Their manager said and go out of the room.

The boys were just quiet and stares to the floor.

"Manager-nim is right... we should be strong for y/n..." Yoongi said.

"Let's cheer up! Let's not act like she's dead, because y/n is still alive! Don't be stupid!" Yoongi added.

The boys look at him, he was placing his hand in the center, waiting for them to stand and place their hands on the top of it. Namjoon and Jin stands up and came to yoongi with a smile. The both place their hands on the top of it. Then little by little the others join in, except for jungkook. They look at him.

"Kook?" Jimin asked.

He look at them... and he shows a small smile and came to them.

"Alright... we're bangtan... we're strong... let's stay positive for y/n. Anything to say?" Namjoon asked.

"We should believe to y/n... and follow her, I know that she's doing this for us. So let us do our best to our performances for her." Jin said.

"For y/n?" Namjoon said.

"For y/n!" They all shout and let go.

They all end up smiling, comforting and hugging each other. If their manager didn't came... if he didn't care about them... they will be not like this. Not strong. Not positive. And not bangtan.
