[Intro: Felix]
"Hey, you wanna come in?"
[Verse 1: Yuna, Hyunjin]
Move over, and here I come
Last time was just a warm-up, umm
This time, it's for real party (Oh)
Stay out of this if you can't handle it (Hol' up), yeah
Gosh, you must feel tight
Let it all go and enjoy yourself to the full, everyone
Turn off the light and light up your eyes all night
Stop hiding your excitement and let it all out (Oh)
[Pre-Chorus: Seungmin, Bang Chan]
I'll walk out that door to see everything I wanted
I can hear the music playing on the other side of the door
I shout my lungs out, I don't have time to hesitate
[Chorus: Felix, Hyunjin]
Hey
Come inside now
Hey
[Post-Chorus: Lee Know, Hyunjin]
Authorized personnel only here back door
Authorized personnel only here back door
Authorized personnel only here back door
If you want to be authorized
[Verse 2: Changbin, Han]
Ayy, I guess this is it, it's time to think ready to go
This body suffered enough from having a bad owner
I'll make it up to you, so follow follow me back door
It's okay since it's not SECOM
The sound that I'm hearing is a fanfare
Let's play all night long, what I need is more caffeine
Come if you want, the passcode is Open Sesame
[Pre-Chorus: Seungmin, I.N]
Everything looks different, and at this moment
Everything turns out to be perfect
I'm watching my fantasy unfold before my eyes
I shout my lungs out, I don't have time to hesitate
[Chorus: Han, Felix]
Hey
Come inside now
Hey
[Post-Chorus: Changbin, Hyunjin, Felix]
Authorized personnel only here back door
Authorized personnel only here back door
Authorized personnel only here back door
If you want to be authorized (Knock, knock)
[Bridge: Bang Chan, I.N, Seungmin]
Lights out
Yeah it is getting more glamorous as time passes
Yeah, we gon' do it right now, do it right now, baby
Come to your senses from now on
Look at this world and keep it in your eyes
Your heart pounds, rum, pum, pum, pum
[Chorus: Felix, All]
Make 'em say, "Wow, wow, wow," yeah
Bring 'em all, all, all, ayy
Sing along, along, along, hey
Three, two, one
[Post-Chorus: Lee Know, Changbin, Han]
Authorized personnel only here back door
Authorized personnel only here back door
Authorized personnel only here back door
If you want to be authorized (Knock, knock)
[Refrain: Bang Chan, I.N, Lee Know, Yuna]
The bell rings and we go crazy
Today, we do our thang again
The bell rings and we go crazy
Tonight, I bark again, ayy
The bell rings and we go crazy
Today, we do our thang again
The bell rings and we go crazy
[Outro: Felix]
Hot, hot (Yeah), hot, hot, ah
Hot, hot (Oh), hot, hot
"Hey, you wanna come in?"
Hey, you wanna come in?
