It was rainy outside, the weather was foggy and it felt like there would be a thunderstorm.

But no one in the BTS mansion really cared, for today they were all on leave and would be exercising together, the most trusted guards and BTS, the private gym underground.

Jungkook had never gone there, for it scared him, he used to see how all the weapons and stuff were taken there sometimes and even felt like he heard gunshots. To be true, there were two underground levels, but Jungkook didn't know that, he didn't need to actually.

The first underground level had a big gym, and a theatre area, the second and the last one was the place where BTS and a few guards trained and weapons, important folders and documents were kept. It was usually locked and only opened with any of the BTS's fingerprints.

So, right now, as Kook was eating pancakes, sitting on one of the kitchen stools in the kitchen, dressed in a loose grey t-shirt and sweatpants, with socks on his feet, and his hair lying over his front forehead was looking at Jin who was preparing protein shakes for the other boys. Jin declined the gym offer, saying he'd stay with his son, aka Kookie, and no one else said anything for they knew Kook can't be left alone, even if he is in a big space. The boy was supposed to be attracting trouble, can trip over the air just like Jimin, sometimes even slipped or made something fall. However, don't share this with anyone but Jin thought it was because of the time he'd spent with Namjoon and Jimin, he got their traits as his habit.

The silence didn't last long in the kitchen, for the others arrived, all changed into their workout outfits.

TAE- Hey my bunny!

Jungkook turned, with pancakes in his mouth, his cheeks puffed out, as he was chewing slowly, like a rabbit, and Tae kept a hand on his heart, winking at the boy, making the latter giggle, but you know what...

Jungkook choked.

He began to cough, as Jin turned around to listen to the noise. He sprinted towards Jungkook and began to pat his back and give him water while glaring at Taehyung who was about to step close to his bunny but couldn't, cause mind me, the glares WERE scary.

Soon enough, Jungkook stopped coughing, and Tae finally sat down, beside him, simply looking at the boy who was carefully eating small bites out of the carrot that Jin gave him.

Jungkook's gaze once again went to the elder who was staring at him, but this time he simply shared a piece of the carrot, to which Tae simply came close to the younger, and held his cheeks between his own large palms and ate the end of the carrot sticking out from Kookie's lips, making the latter turn into a live tomato.

JIMIN- Alright! Alright! Love birds! Control now, let's go Tae, here is your protein shake.

Tae stood up, and held the younger by his waist, taking him off the tall stool he was sitting on.

TAE- Take care, baby.

Jungkook nodded and showed his bunny smile, to which Tae pecked him on his forehead and proceeded to go out of the room.

When they were gone,

JIN- Alright, Kookie, what would you like to do today, hm?

JUNGKOOK- Can I draw, hyungie?

Jin smiled and nodded, motioning Jungkook to come to the living room with him.

Jin turned on the television for himself, while Jungkook waited for the maid who had gone to fetch his drawing supplies.

And soon enough, the younger was busy drawing small doodles, sitting on the carpet, in front of Jin who sat on the couch, with the Tata plushie on his lap, and a lollipop in his mouth.

That's when Jin got a call and looked at it to see his restaurant's manager calling him.

JIN- Kookie, bun stay here, I have to attend a call, okay? Don't move.

Jungkook nodded and showed a thumbs up and Jin went away for a bit, picking up the call.

JIN- Hello, yeah say what is it?

MANAGER- Sir, there has been an issue, I'm afraid you'll have to come to the restaurant.

JIN- Seriously, I took leave for a day and there's an issue. What do you guys even do, huh?

MANAGER- Sir, actually, the desserts that had to be prepared and delivered were returned by the customer saying they don't taste good, and now the customer is fighting that we aren't on time.

JIN- *sighing* Fine, I'll be there in 15 minutes or so, till then don't do anything which can get you in any more trouble.

MANAGER- Absolutely sir, thank you!

Jin cut the call and went back to the living room area, where he saw the younger was giggling at the cartoon show playing on the TV. He had slipped into little space.

Jin smiled slightly, but then,

JIN- Sheesh, I need to make Jungkook sit in the gym itself, can't leave him with the maids either.

He groaned and went closer to Kook who was busy popping his lollipop in and out of his mouth.

Jin opened the door of the gym and was met by a cold gust of air, as the air conditioning was quite strong there.

Everyone almost stopped doing what they were, the guards especially, and bowed to him to which he smiled slightly and moved inside, only to be followed by a wondering Jungkook, who had a lollipop in his hand, was looking around in amazed, and the other hand is held by the elder. A maid followed both of them, with a thin blanket on her arm, and a tray that held a big bottle of banana milk and a few crispies to one side.

Jin walked to the end of the gym,

There they were, in the gym surrounded by glass doors separating them from the guards in the outer workout area,

Jin held the boy closer and took a step ahead as he was scanned top to bottom and the glass door slid open with a small 'ting', announcing his arrival making the others stop what they were doing.

Jimin was working on the lat pulldown machine, Suga near the leg press one, Namjoon was at the pullup bars, Hoseok at the treadmill, and Taehyung in the far corner, doing incline dumbbell curls. *search the terms if you want*

Taehyung was shirtless, his biceps flexing as he worked with the heavy weights.

(...)

Apparently, he was facing the other side and so he hadn't seen Jin or Jungkook, but the younger one saw him, definitely, and immediately shouted in excitement,

JUNGKOOK- DWADDAA!

Taehyung dropped the weights and stood up, wiping his sweat with a towel, and smiled looking at Jungkook who was trying to come to him but being restrained by Jin who didn't want the boy to stumble over or fall down over anything.

Taehyung walked towards Jungkook, making the younger one smile wider when he saw the elder's tattoos on display, oh how bad he loved all the inking his dadda had.

TAE- *smiling* How come you're here hyung?

Jin finally left Jungkook, who jumped on Tae, as the latter held him and sniffed his neck.

JIN- Unfortunately, there's been a small issue at the restaurant and I need to go, so I thought of bringing Kook here since I didn't want to leave him alone.

Taehyung nodded.

NAMJOON- I hope it isn't something serious, Jinnie?

JIN- Nah, it's a small issue, I just scared my manager a bit, you know that way they work efficiently.

Namjoon laughed,

JIMIN- Don't worry Hyung, you can go without any worry, Kookie will be safe, and call any of us if you need help, OH GOD, YOU WHIPPED ASS STOPP IT!

For Tae was simply staring at the boy in his arms, who was looking everywhere but at Tae for the boy was completely blushy.

Tae sheepishly smiled, and Jin sighed.

JIN- Here, the air conditioners are on, and yet you're sweating. I don't want my baby--

TAE- My baby, Hyung!

Jin smacked the boy who pouted, and Jungkook giggled.

JIN- The blanket! And here's something for Kookie to eat, I'm keeping these here, and mind me, take care of him, even if you have to stop exercising. *seriously*

The others fastly nodded, and Suga simply shook his head and continued what he was doing.

Jin went out after petting Koo's forehead.

Welp, right now the situation was like this, Jungkook was covered with the thin blanket and sitting on the rubber mat of the gym, watching his dadda do pushups in front of him, while the younger sipped on his banana milk and popped one or two crispies in his mouth in between.

That's when Suga came and sat beside Jungkook who looked at him with head titled, straw still in the mouth.

Suga was slightly panting for the exercises he did, and so Jungkook offered him the water bottle kept beside him.

SUGA- Thank you, kiddo.

Jungkook smiled.

Suga somehow kept looking at the boy, then petted him on his head, ruffling his hair, and stood up, moving towards Jimin who was panting on the ground.

Jungkook frowned but then kept smiling, as he didn't mind being babied by their hyungs.

After around an hour, BTS was done, and Jungkook was fast asleep, on the rubber carpet itself, wrapped like a burrito in the blanket. Only his head was visible. As they were walking out after wiping their sweats, Taehyung was the last one, as he had already told the others that he'd take Jungkook with him.

And so, he picked the boy up, still covered with blanket and walked out, up to his room where he made him lay down, covered him properly, kept plushies and pillows around him so that he doesn't fall, and moved to freshen up, not before pecking softly the boy on his pouty lips.
