Namjoon sighed in relief as he looked at the screen of his computer, a dimpled smile gracing his handsome features ,he had finally finished  mixing the music for a song he had been working on for the past few months. The song was an emotional sort of song about friendship he had written while thinking about the love between them and their new little brothers, the members of TXT. 

Namjoon decided that he would put Jin's voice on it first as a test and then he eventually pass the music to the maknae line ,as for the rap parts he had already decided which parts he wanted to give to J-hope and Suga ,and the parts he would be rapping. He could already visualize what the song was gonna turn out to be and he was feeling very proud of himself that day.

He saved his work and was about to turn off the P.C to retire for the rest of the day ,he heard a pair of small knocks.  The knocks were so low ,Namjoon had to strain to hear them. 

''Come in'' said Namjoon.

Whoever was knocking stopped knocking for a moment but then continued to knock and didn't come in. Confused because of that, Namjoon walked to the door and opened it. 

Standing in-front of the door was a little boy of about three years old  ,wearing a shirt far to large for him, his dark brown hair tossed and his big brown eyes filled with tears. 

"Hey little one... what's going on? Are you lost?" Namjoon didn't consider himself as the best person to handle situations like this , but he was obviously not a monster to let a crying child wander around alone. 

The little boy sniffed ,wiping his tears with his small hands ,and nodded.

"Help... help me ,I dunno where am.." said the little boy with a pout on his face, almost like he was about to cry again. 

 "Ok, little one... don't cry, come on. Be brave, you're here with me and I'm gonna help you, ok? But I need you to be brave, could you do that for me?" asked Namjoon , a smile on his face as he grabbed the boy and lifted him up ,carrying him with care. The baby boy immediately put his arms around Namjoon's neck ,nuzzled into his chest and laid his head on Namjoon's shoulder.

"Iam bvave" The little boy said, and Namjoon tried very hard not to melt because the boy was really cute and he always had had a soft spot for little babies

"Ok, baby, could you tell me your name, please? I'm Namjoon but you can call me Joonie ." He said while cooing at him softly so the baby could calm down.

"Soobin..." slurred the little boy.

"Oh, just like our Soobin from TXT " Namjoon thought out loud.

He found it very strange that this little boy was wandering around the building with just that large t-shirt and he clearly could see that this boy was naked under that shirt. 

''Maybe he belongs to someone in the staff or the makeup noona's '' thought Namjoon,'' But why would anyone bring their baby to work just wearing such a big shirt and nothing else''

"Yesh!" The baby boy squealed with excitement. "T... sh... T" He tried his best at saying the name of the band. "Me... Junie, Beommie , Hyunnie and Ning-Ning.. I am shupposed to look for help, Im da leader... I haf to.. I haf to... am bvave..." The boy mixed his words as he tried to speak or explain what he was doing and Namjoon was very confused while walking in to the corridor. 

"Ssh, ssh... calm down, baby , I'll get you to your mama soon." Namjoon hugged the little boy..

Hoseok came out of his studio and squealed when he saw Namjoon with a baby. 

'' OMG THIS SO CUTE ! WHERE DID YOU FIND THIS ,CUTIE'' squealed Hoseok, running to Namjoon ,cooing at the baby.  The baby flinched at the high pitch and hid his face in Namjoon's chest.

Hoseok realized this and looked at the baby apologetically. 

'' Iam sorry ,baby,I didn't mean to scare you'' said Hoseok in a lower tune of voice and began to pat the baby's back in a soothing manner,at which the baby peeked at him a little still hiding his face in Namjoon's chest. 

"Hoseok... this... this may sound crazy, but... this little boy says his name is Soobin" Namjoon said as calmed down the baby who was sobbing softly.

"Oh, just like our Soobin, the  baby TXT leader" the other boy smiled when he saw the baby peer at him more at hearing his name . Hoseok tried to make him smile a little by making weird faces and sounds.

"No... well, yes. But what I mean is that this kid said he is Soobin... that Soobin." Namjoon said with more concern on his face . 

"Namjoon, why would you think this child is that Soobin? Last time I checked Soobin was 19 and taller then all of us. He is just a child, he's lost and  scared. Kids make up stories all the time and by the way he seems like he's three years old why would he..."

"Hyungs!'' 

Jimin interrupted their conversation, abruptly, running towards them with a child on his arms too. The little baby seemed to enjoy that ,giggling as he gave a bright smile

''You won't believe this! There's Soobin, thanks God! relief spread across Jimin's beautiful face. Meanwhile Namjoon and Hoseok were in shock as they watched Jimin approach them with another child in his arms ,that was now  waving at them with a smiley face.

"Binnie, you got lost?" The boy asked and Soobin lifted his head and smiled at the sight of his friend.

"Junnie, I fand someone that is gon to help us!" Soobin said with a smile on his face.

"Jimin what's happening?!" Hoseok asked panicking while Namjoon looked lost as well. 

"There's no time to explain. Come with me, Taehyung is with the other kids" Jimin's expression changed into a one of worry. The trio with the babies ran as fast as they could down the large corridor, the hall of offices and meeting rooms and to the next hall where a training room was located which TXT used from time to time. Namjoon and Hoseok were right behind the smaller boy, Namjoon grabbing the baby safely in his arms.

They made it to the room where Taehyung was singing, clapping and dancing with three other children that were laughing and smiling with him as they danced together.                                     Taehyung had a children's song playing on his phone and was trying to distract the three crying boys that Jimin and he found,  when they went to the training room to watch TXT practice. Taehyung loved children, even in a fan signing whenever a fan brought  children, he would put them on his lap and play with them. So it wasn't strange seeing him playing with the children and enjoying it himself as well. 

" What is happening? I need an explanation , right now!" said Namjoon put down Soobin Jimin did the same with Yeonjun, looking with a fond smile as the kids reunited with each other again ,they hugged, happy that their leader made it to the room with them again just as he had promised.

Taehyung handed the children his mobile phone ,so they could watch a video on YouTube while they figured out what was happening and how it happened. The kids sat down around the phone and happily  watched Paw Patrol, more at ease now they were together.

"We don't know, honestly'' he said confused 

"We came here to watch them practice and we found them like this. All of them wearing those large t-shirts and crying because Soobin had left to find help. Yeonjun is the only one  who knows how to talk more properly and he was bent on trying to protect the other three babies. So he told us a little of what happened." Jimin explained .

Hoseok had called Jin now and told him to come to the training room due to an emergency.  

"Yoongi and Jin are coming right now, Jungkook said he was going to change his clothes and would come right after. I just told them to come quickly." Hoseok said.

"Is this a prank or something ?" Namjoon asked, but it was more rhetoric than a real question.

Namjoon pulled his mobile out and searched for BangPD's number.

"I don't know. Why would they try to prank us like this? This kids were alone and crying, they must be so good actors to cry like that." Jimin couldn't take off his gaze from the children, they were so small and soft, and their cute behavior made Jimin felt his heart melt.

"Oh, also, Jimin, remember what Yeonjun told us" Taehyung said.

Namjoon had called BangPD who had said he would contract the manger of TXT.

"Hey, what's going on? ..." asked Yoongi as he  entered the room and stopped right away when he saw the amount of kids that were playing with  Jimin and Taehyung. "What's with all the kids here?" He asked, clearly confused . Jin came a moment after him and smiled immediately when he heard the cute and soft laughs of the children watching the cartoon on Taehyng's phone.

"Awww, little babies, how cute..." Jin  cooed but stopped when he saw the looks of concern on the other members faces.. "What's happening?" He asked.

"I talked to BangPD, he said he doesn't know what are we talking about but he's coming with the manager of the... babies." said Namjoon. At first BangPD had thought it was just a joke but Namjoon had begged him to come ,so he had agreed.

"What babies? Who are this little baby boys, huh?" Seokjin asked, Yoongi watched the other members expecting and answer to.

"Well... We think they are TXT group, Yeonjun, Soobin, Beomgyu, Taehyun and Hueningkai." Jimin responded..

''Have you gone insane ?''
