"Joonie and I are going out," Kim Seokjin (or Jin) remarks, strutting for the front door of the giant house that BTS had moved into. He's wearing a bright pink coat over a nice white dress shirt and black pants. "So you better behave!"

"Awwww. For how long?" Jeon Jungkook (or Kookie) asks, downing a box of banana milk.

"Until the morning," Kim Namjoon (or RM) says. He bites his lip, the corners of his mouth twisting up, sheepishly.

Jin whacks RM in the shoulder, causing the self-proclaimed leader of the popular K-Pop group to rub his arm.

Park Jimin (or Jimin) looks at Kim Taehyung (or V), who shrugs.

"Yeah, what Joonie said," Jin says, smiling from ear to ear. "And SOPE is in charge. I expect you guys to all behave for them. That means you, Jimin-ssi!"

All three of the infamous Maknae line (Jimin, V and Kookie) all groan and roll their eyes.

"Sounds good to me!" Jung Hoseok (or J-Hope) exclaims, clapping his hands together. "We'll have fun!"

Min Yoongi (or Suga) jumps up from his spot on the couch. "You know what happened the last time this happened?"

"My hand remembers," Jimin says, smirking sassily. "Does your butt?"

Suga shoots him a glaring look. Jimin bursts out in laughter, stumbling in place at the memory.

"Don't worry any at all, Jin-ah-hyung, we'll be on our bestestestest behavior, sir!" He gives a salute and maintains a serious look on his face.

Jin pinches his nose. "That's reassuring, V."

V bursts and gives a signature box smile.

J-Hope walks forward as RM opens the front door to leave. "You leave everything to Yoongi and I. We got this!"

Kookie flaps a limp hand up and down at the wrist, sucking on the straw of the banana milk's box.

J-Hope guides the older two men out of the door, hurrying them up with a shooing motion. "Enjoy your date. We'll be fine. Have fun, go-go! J-Hope's got this! You can trust Hobi. Borahae and kisses."

"We'll be back in the morning," RM calls out as the door is slammed, trapping the two outside and J-Hope inside.

J-Hope leans against the door and looks at a horrified Suga.

"Why do I get the feeling that this is going to--" Suga begins to gumble.

"HELIUM TIME!!" Jimin shouts out, jumping onto the couch and scaring Suga enough to make him jump.

"Yesssssss," V says, rubbing his hands together.

"I got the balloon!" Kookie yells, running out of the room.

"This is going to be so much more fun than the butt-slap game!" J-Hope remarks, locking the door and walking over to Suga.

"You just have to torment me, don't you," Suga growls, putting his hands on his hips.

J-Hope puts a hand on his shoulder with a stern face. But he can't keep it, bursting out in laughter and a smile. "We're having fun! And what's wrong with inhaling helium from a balloon while SINGING KARAOKE!?"

J-Hope does a cute little dance of excitement as Kookie races back in with a bag of balloons. He has one in his hand that is blown up already.

Suga sticks his pinky finger into his ear. "Why do you have to scream that?"

"Because he's excited," Kookie says in a high-pitched voice, before he breaks down in Chipmunk-sounding giggles.

"Give me one of those!" Jimin screams from the couch he is jumping up and down on.

Jimin and V both take a balloon out of the bag and blow it up. Then they suck out the helium from it.

"Hey V," Jimin begins, trying not to laugh at his ridiculous voice.

"What, Jimin?" V says, looking at him, anxiously. He sucks in more air, his eyes wide and wild.

"It'd be really funny if Suga did this and acted like us?!" Jimin says in his high-pitched Chipmunk voice.

"Yeah!" V agrees.

Suga shakes his head, moaning. "This...is going to be a long night."

"Let Hobi have one," J-Hope exclaims, digging into the balloon bag. "Which karaoke song should we do first?"

Jimin sucks more helium from the balloon and bursts out with, "Crown!"

"Yes!" V agrees. "From our hoobaes!"

Kookie sets up the TV in the main room that they are in, laughing as his helium wears off. He begins to softly sing the chorus to himself as he scrolls through the songs on the karaoke machine to find the song from Tomorrow X Together.

The music begins and Kookie blows up another balloon quickly and inhales the helium to join the others. V joins Jimin, jumping on the couch. J-Hope grabs mics and passes them out to everyone.

Suga falls with a heavy sigh into a chair that is sitting by the wall. "Long...night..."

Jimin begins the song with an "Uh, yeah. Oh..." before J-Hope and V join in unison with Kookie to sing the first verse.

There's lots of laughter and screaming high-pitched voices that follow.

As the song hits the chorus, J-Hope turns and screams into Suga's face.

Suga glares at him, trying not to lose his temper.

The song ends with Jimin falling off the couch to the floor and playing it off as something he was supposed to do.

Suga runs for the door and tries to throw it open. It doesn't budge. He'd forgotten about it being locked by J-Hope! "LET ME OUT OF HERE! HELP!!"

"Oh, Yoongi-ssi," Jimin's voice giggles.

"Suga-hyung, come on, join us," Kookie laughs and stumbles over like he is drunk. He snatches Suga's hand and pulls him into the middle of the party against his will. "It's lots of fun!!!"

"WE SHOULD SEND RM AND JIN A VIDEO?!" V suggests, jumping with a flourish off of the couch and landing on the floor, almost on top of Jimin.

"OMG, YES!" Jimin shouts out.

"I'm going to put on Epiphany!" J-Hope exclaims as they all helium-up again. "Everyone's favorite and go-to song!"

The music and new song begins as V whips his phone out and begins to record a video of them to send to RM and Jin. They sing along in their Chipmunk vocals and smash an unhappy, grumpy Suga in the center of them.
