large age gap between aera and the boys because... well, demand ;)

the door opens and bts walks in, gasping and cooing at the sight of the room they'll be shooting in today. one of the crew members did tell them today's special, and now looking at the set they're just growing more curious every second. they stand in the middle, still having their eyes wandering around the big room which is divided into compartments, some having toys, one with a television, a kitchen, a bathroom, and even a single bed.

"do we have to act like a baby today?" hoseok asks with a frown, pointing at the micky mouse bed while jungkook beside him is playing with a ball that he just picked up from the floor.

"everything looks so cute," taehyung cooes, "look at that! the small bathtub!"

"it's like we're giants in front of this," namjoon chuckles amusedly.

"reminds me of aera," jimin smiles at the stuff looking like everything around them has shrunk into a tiny size to enhance it's cuteness.

"what are we doing today?" yoongi asks.

the director smiles, gesturing the members to sit and passes a bowl full of papers of different colors, letting each member pick one. jimin being on the extreme corner, unfolds his paper first, showing it to the camera and the members, "jimin," taehyung reads and unfolds his paper, frowning when his paper reads jimin's name too, "i think something's wrong with these,"

"no, it's all right, please open the next one." pd nim says and yoongi nods, showing his paper to the camera which says jungkook's name.

jungkook presses his lips in confusion, opening his paper and finds his name, then he takes namjoon's paper and finds jimin's name again. jin and hoseok open their folded papers too and show the same name to the rest, "jungkook? i think these are the teams for today..."

"yes," pd nim nods, "jimin and jungkook will have separate teams whose members are now decided. please sit with your respective team,"

jimin, taehyung and namjoon sit from the right, while jungkook, jin, hoseok and yoongi sit from the left, waiting for further instructions. but instead of words, a sound of familiar squeaky shoes enter their ears, making their heads turn to the door where aera pushes the door open and enters in with a wide grin, waving at her oppas.

"aera?" jungkook gasps, breaking into a smile as he notices the way she's dressed– a white top and denim skirt that is apparently too short and has her matching blue underwear visible. "aw c'mere," he opens his arms and makes her sit on his lap, straightening the skirt  and kisses her cheek, "riri looks so pretty today. who got you ready?"

"noona," aera points at the back of the cameras, getting a few chuckles from the team.

"hi oppa," she turns then, waving at jimin and the rest of the boys, "i– riri comin' to playing wid you,"

"ah is that so?" hoseok smiles, patting her head, "what do you wanna play?"

"dere," aera points towards the toys, making the boys gasp and turn to crew members who nod.

"so aera's already here, and if you haven't guessed yet, today's concept is taking care of a baby: being a babysitter of a three-year-old."

"ahh," the members nod slowly, happy with the idea as they always love spending time with aera and playing with her.

"there are some rules you all need to follow. since we have got the teams already, we know it's a team game today. you all will stay in this room with aera for the whole day, and your job is to take care of her. means, you will have to do all of her work and chores, and you'll get some points for that. for some things like cooking, both the teams will prepare a meal for her, but the one she chooses to eat will win, and that team will be given some points. the more time aera spends with your team happily, the more points you'll get. if she cries or whines or gets upset about anything, that team will have some minus points. at the end of the day, we'll see which team has more points to decide the winner."

"ah okay, so that's the reason jimin and jungkook have been put in different teams," jin laughs. 

"it's gonna be so much fun today!" hoseok beams, holding aera's hand, "please spend more time with us okay?"

"no aera, please spend more time with us. i'll give you a chocolate," taehyung smiles, carrying her in his arms.

"also," the director adds, "every hug and kiss aera gives you willingly will add points to your team. you cannot force her."

"she kisses jungkook the most!" taehyung whines and jungkook smirks in victory.

"why are you even trying, we're the winner," jungkook flexes, leaning near his sister and points at his lips, making aera lean in quickly, kissing him and giggles happily. "see?"

"she'll get bored tae," jimin scoffs, "after some time, she'll smack that smirk off his face. just watch,"

"true," namjoon snickers, "anyway, let's start."

"alright, the routine is written on the white board, you have to follow that."

the boys turn to the side, following the directions and read along the schedule, "brushing the teeth, brunch, bath, nap, snacks, play time, learning, dinner, sleep," jimin nods, impressed with the detailing, "wow, okay, let's go. we've to win."

namjoon nudges his arm, nodding towards jungkook's team who's already on their way to talking to aera and taking her to the bathroom. jimin, taehyung and namjoon follow too, strategically crouching on the floor, near the toddler before the opponent team does. aera however, leaves them there, walking away to where a few toy cars are placed and sits down on the floor, playing without paying much mind to the elders.

"aera," jin calls, clicking his fingers and smiles, "come here, we gotta brush riri's teeth,"

"no bwushing riri teeth," aera shakes her head, showing her car to jin, "i' playing now,"

"you can play later sweetheart, come here for now." he tries again and aera shakes her head, crawling away and stands up, running to the opposite corner, making the eldest sigh.

"hey i know my baby will come to me," jimin smiles, holding out his hand but aera shakes her head again, sticking out her tongue and sits on the little pony which rocks with her movements, making her giggle.

"we have to brush riri's teeth so she can smile prettier," hoseok tries this time, nearing her slowly and holds her hand, "you want your smile to be pretty right?"

"pwetty like oppa,"

"yes, and we need to brush our teeth for that," he says, helping her get down and heads back to the bathroom with area, near the sink, "see we have different colors of toothbrushes for riri,"

"yes, which one do you want?" jin nods, joining hoseok with an impressed smile that he could bring the child over and trick her into brushing her teeth.

"bloo," aera picks up the blue one and smiles, "i' making my smile pwetty like 'obi oppa,"

"yes, hobi has such a pretty smile," the eldest says, putting some toothpaste on the tiny blue toothbrush and brings it closer to her mouth as aera's already showing her teeth to him, making the job much easier. jungkook and yoongi shake hands in victory, glancing at the camera with smirking faces as they gain points and their opponent team has scored nothing.

"koo, b'ush yo' teef," aera muffles out with the brush in her mouth as she bites on it gently, not letting jin brush her teeth.

"i did it before coming here," jungkook smiles, patting her head.

"don't bite the brush princess," jin says, slowly trying to pull it away which seems like a game to aera for she giggles and bites harder. he sighs, opening her mouth and makes her stand and lifts her up to help her reach the sink, "c'mon now rinse your mouth," he says, holding a cup filled with water and lets her take a sip.

aera nods once, doing as she's told and leans forward, spitting out the water in the sink then repeating the process two more times and shows her teeth to jin in the mirror, "riri havin' pwetty smile,"

"yes, good job," jin chuckles, "everyone clap for riri,"

the boys clap instantly, making aera cackle excitedly, clapping her hands too and hugs jin. the team members gasp in happiness, giving each other high-fives as they got more points and it's just the starting.

aera's left down to play for some time, while two members from each team are engaged in cooking and the rest are around the toddler, making sure she's not doing anything potentially hurtful and also trying to get some extra hugs and kisses.

"this is unfair," jimin mutters, chopping vegetables on the counter and looks at the camera, "the other team has got both jin and yoongi hyung, even jungkook and hobi can cook there. but in my team, it's only me."

"so that you can lose," jungkook snickers, sitting with aera and makes her face him, "hey baby,"

"hey baby," aera repeats, pushing her car towards jungkook and stands up, taking the remote control with some confusion evident on her face, letting him know that she's having trouble operating it. "koo, dis..."

"what? is it not working?" jungkook takes the controller, pressing the forward button and the car roars straight ahead, colliding with aera's feet, making her flinch at the sudden movement from the car which happened to be stationary till now. she climbs on jungkook's lap, holding the controller with his hands and presses another button, but nothing happens this time, making her pout.

"only one button at a time," jungkook tells her, removing her hand from accidentally pressing two buttons together, "now try it,"

aera presses the button jungkook pressed earlier and smiles as the car starts moving, "yes! i did it!" she cheers.

"now give me a ki–"

"aera, come here baby, it's time to eat." jimin calls, drawing the kid's attention from jungkook to towards him. she slips down from jungkook's lap, running to jimin with a sweet giggle rolling off her lips and hugs his legs, making him smirk in victory at the opponent team. "here's my little princess, will you give oppa a kiss?" he carries her in his arms, chuckling as the toddler kisses his cheek and then his lips.

"yess!" taehyung and namjoon cheer together.

"you cheated!" jungkook points at the elder brother, "she was going to kiss me!"

"but she didn't," jimin scoffs, "now get away, riri missed me,"

"mm-hmm, i mish you oppa," aera nods, sticking to jimin while jungkook groans lightly.

"hey, aera come we have better food for you," he tries again, holding out his arms as hoseok joins him too, "riri will eat with kookie and hobi oppa,"

"i want butter food," she hums, leaning towards hoseok and jungkook nods in satisfaction. "where' butter food for riri?"

"there, jinnie and yoongi oppa are cooking," hobi tells her and jungkook nods, giving her a strawberry to eat till the food gets served for her.

"aera, jiminie made mac-n-cheese for you," namjoon says, "and we have a lot of heathy veggies, so riri can become strong,"

"no," aera shakes her head, "i' no wike veggies. butter food,"

"better," jungkook snickers, "say better,"

"butter," aera tilts her head, "gi'mme butter food!"

"okay fine," he sighs, "but you've to give us a kiss first,"

"no," she looks away.

"ah c'mon, y'know oppa loves riri right?"

"but no kissie, i' tired,"

"we don't get tired of kisses princess,"

"pwincess gettin– tired, i wan' butter food! gi'mme!"

"hey shh, no whining,"

aera smacks his face, wriggling in hoseok's arms until he puts her down, watching her heading back to jimin. jungkook hisses in pain, turning away with his hand on his right eye, grabbing attention from the crew members and his hyungs.

"are you okay?" hoseok being the closest one asks, pulling away the younger's hand gently and winces lightly, "she scratched the side of his eye,"

jimin sighs softly, glancing at aera who looks unbothered, playing with a spatula and a spoon. he then looks at the production team, nodding his head towards his brother subtly, gesturing the assistants and manager to check him and help him out if needed. the said people spring into action, bringing jungkook out of the camera frame for a while and check where he's hurt.

"oppa," he glances at aera as she's holding out the spatula for him, making him sigh.

he takes it from her hand and makes her sit on the counter, making her look at him, "why did you hit kookie?"

"mm?" aera pouts and mumbles, "i no' hit kookie,"

"i saw you did." jimin leans down near her, pointing towards the production team where one of the staff assistants is with jungkook, "he got hurt. you should never hit anyone, aera. i told you it's bad, didn't i?"

"oppa, no... i– uhm riri no' hitting koo, me a good baby,"

"good babies don't lie," he emphasises, "and i can see aera's lying, that means she's becoming a bad baby."

"nooooo!" aera whines, "i' good!"

"then tell me why did you hit kookie?"

"koo keep asking kissie, i wan' butter food– i' hungwy... koo saying– only wan' kissie,"

"okay, but you shouldn't hit him. don't do that again, alright?" jimin sighs, placing her on her feet and pats her head, "now go to kookie and say sorry,"

aera nods once, holding jimin's hand, taking little steps towards jungkook who nods at something the assistant girl says to him. looking in the mirror, he chuckles dismissively,  only to look down feeling a tug on his pants from the tiny hand of his little sister, looking scared and upset.

"koo i' sowwy," she mumbles, lifting up her arms, and jungkook crouches down near her, bringing his between his arms.

"it'a alright," he smiles softly.

"riri bad baby, i don' hurtin koo,"

"aw it's okay princess," he chuckles, "i'm fine, it's just a small scratch that's all. riri's not a bad baby,"

"riri wuv you," aera mumbles, hugging him tightly and pecks his lips.

"i love you more baby," he smiles widely, giving a thumbs up to camera and smirks at his hyungs, holding aera in his arms as he stands knowing she won't let go of him for a while now and that is enough for them to win.

after choosing the food jin and yoongi cooked over jimin's and actually not letting go of jungkook despite all kinds of efforts from jimin, taehyung and namjoon, it was almost time to wrap up. jungkook's team was the clear winner as aera's still on jungkook's lap, her eyes closing slowly after drinking her milk.

jungkook pats her back gently, feeling too proud of himself today for winning like this with his sister. once aera's fast asleep, he lays her on the bed, covering her with a blanket and stands up, walking to the front of the cameras, "so you see we won, that's how you take care of kids."

"we won!" his team whisper yells, hugging each other while the lost three sigh in defeat.

"it's all because of his over the top acting," taehyung mutters, "she was guilty for hurting him and he took advantage of that."

"i know right," jimin glares at the younger brother, "he's such a cheater,"

"we could've easily won today if jungkook played fair. he doesn't like to lose at all," namjoon whispers.

"a wise man once said, you can either have success or excuses, not both." jungkook states mockingly eyeing the lost team, laughing with his members.

"what's the penalty for today?" yoongi asks.

"the winning team along with aera, gets free dinner at the restaurant of their choice. and the  losing team will clean up this place."

"no..." taehyung gasps, exchanging shocked glances with jimin and namjoon, then turns to production team, "we're okay with cleaning up, but why are they getting free dinner?"

"because we won and you didn't," jungkook smirks, throwing his arm around taehyung's neck, "good luck v-hyung, and jiminie hyung, and rapmon hyung," he grins.

"i feel bad for you all," jin shakes his head, "but don't worry, i'll post pictures for you,"

"yep! me too!" hoseok snickers, "we'll head home now. happy cleaning y'all!"

"yeah bye," jungkook laughs, carrying aera from the bed and pats her back to let her know that she can still keep sleeping.

"thank you for today, it was so fun with aera. army got to see this unfiltered side of us when we're with her. and trust me, it's exactly like this at home," hoseok laughs.

"yeah, i enjoyed a lot and i'm sure aera did too." jungkook smiles, "run bts will continue, till then bye-bye. dallyeora!!"

"bangtan!"
