Their choreographer handed them the mics and placed the caps on their spot.

"3! 2! 1! Leggo!" HOSEOK said and quickly positioned himself.

(What) Now we'll take it
(What) You'd better be nervous
(What) The ultimate king at the end
(What) We are bulletproof
We are bulletproof
Bulletproof

The members didn't say anything while Song-deuk was very much happy with the way the choreo came out.

The name is Jung Kook, the nationwide scale
I pulled all-nighters at practice rooms
Instead of school, dancing and singing
While you guys partied
I gave up sleep for my dreams
I stay up all night every day, holding my pen
After the sun rises, I close my eyes
The double standard and all the opposition
Amid all that, I broke the limit of myself
Meanwhile, some are luckily picked up by an agency
And being forced to rap as they can't sing
Such a waste to call you a rapper

The extreme coordination during Jungkook's verse gave people a jaw dropping moment.

Everywhere I go, everything I do
I'll show you as much as I've honed
All the people who looked down on me are now
(Oh, oh, oh, oh, oh, oh) Hey, shout it out

Taehyung's ocean deep voice gave them chills running down the spine.

Oh, if you've done enough like me, throw a stone at me
We go hard, we have no fear
(Click click, bang bang) We just sing it like
(Click click, bang bang) We just sing it like
Oh, if you've done enough like me, throw a stone at me
We go hard, we have no fear
(Click click, bang bang) We just sing it like
(Click click, bang bang) We just sing it like

"This is the kind of teamwork I want in you all," PD nim said.

(What) Now we'll take it
(What) You'd better be nervous
(What) The ultimate king at the end
(What) We are bulletproof
We are bulletproof
Bulletproof

"They can't help getting out of formations at a time but they do that too in sync," Song-deuk said lowly chuckling.

Look at my profile, I've got nothing yet
Still a trainee and a rapper man, yeah, I do know that's nuttin'
I was worried once but now no need to
You're still amateurs, I'm a major, hope you'll be rotten like that forever
Like Rap Monster says, just like a monster I devour any kind of beat
Deserve to have my name? Guys, come on here
Look at the preview, the change of small fry idol
Haha, the pride of hip-hop guys said it's impossible
But take a look, there's a period in it, I'm possible
Now you satisfied, boy?

"If we managed to perform like this on our debut stage then everyone is gonna love us!!" jimin said.
"Indeed" hoseok.

Everywhere I go, everything I do
I'll show you as much as I've honed
All the people who looked down on me are now
(Oh, oh, oh, oh, oh, oh) Hey, shout it out

"Hyung's vocals have improved so much!" tae.
"You are making me jealous of myself" jin
"Shush, just watch and learn" Song-deuk.

Oh, if you've done enough like me, throw a stone at me
We go hard, we have no fear
(Click click, bang bang) We just sing it like
(Click click, bang bang) We just sing it like
Oh, if you've done enough like me, throw a stone at me
We go hard, we have no fear
(Click click, bang bang) We just sing it like
(Click click, bang bang) We just sing it like

"It is coming, oh my god I am getting so nervous" hoseok.
"Me too" said jimin and kook in unison.

(What) Now we'll take it
(What) You'd better be nervous
(What) The ultimate king at the end
(What) We are bulletproof
We are bulletproof

"They exchanged the mics in front of us and we didn't even notice it" taehyung.

Bulletproof
Bulletproof

Hoseok's moves were crisp and sharp, then Jimin did the flip with grace making them gasp. Jungkook and Jimin's cap part looked so real as of the cap was actually thrown, and the cap looked as if it was stuck on Jungkook's hands, it won't fall off.

The mics were back in everyone's hand within a blink of an eye and there they were standing at an exactly equal distance after the song ended.

The song ended, the members were heavily breathing. JIMIN tumbled down but remained there only. Their CEO motioned the younger ones to pass the water to BTS.

TAEHYUNG was gonna grab it but HOSEOK stopped him, "We may not be in our time... but that's doesn't mean to... forget the rules" he said heavily breathing.

TAEHYUNG being the baby he is started showing his puppy eyes. "Nope they won't work on me... we can't afford you being a member of the vocal line and having a sore throat," HOSEOK stated sternly.

"Exactly fourteen minutes...felt" NAMJOON checked the digital click above them.

"Yah who cares... Song hyung won't know... I'll drink water if I want." YOONGI.

"NO, YOU WON'T... IF ONE ISN'T HAVING IT NO ONE WILL!" SEOKJIN.

"Let them take a break," Si-hyuk nim motioned bts to stay put and quiet.
