*Flashback**

Namjoon exited the store with his favourite, hot chocolate in one hand while he was checking the recent mails on his phone when he heard some faint noises ,it sounded like a child crying. He looked around , it wasn't that crowded probably because it was late afternoon. Out of the cafe he spotted some chairs and tables for customers to sit and enjoy the beautiful view of sky high buildings around.

He felt the sounds coming from one of those tables. He scooted near the third table, peeping under the table he found a small boy crying hugging his knees burying his face in between.

He looked barely 4.

"Baby where are your parents?" He asked worriedly, slowly taking the place beside him. He spoke in the softest tone possible making sure to not scare the boy.

The boy slowly lifted up his head upon hearing His voice.

His fluffy white cheeks and cute nose were now red because of crying. Big brown eyes filled with tears ,small pouty pink lips. He swore he was the cutest baby he has ever met in his entire life.

He flinched a little when the boy suddenly jumped onto his laps wrapping his tiny hands around his broad chest. Placing his head on his chest he began to sob quietly. He could hear low muffling sounds .

His heart began racing , it felt so warm. He also wrapped his arms around him, picking both of them off the ground. Still carrying the boy in His Arms, He Seated on a chair nearby while the boy kept snuggled in his arms like a little koala.

He can't even describe the things he felt at the moment . Every time he is with kids it feels so good to him. His colourless life seems to brighten up. Their little giggles , cute talks, running around ,their cute little mischieves. Everything about them is so precious.

Slightly pulling him away from His chest He saw a few tears still rolling down his cheeks. Taking out His hanky he gently wiped both of his cheeks before placing soft kisses on both the sides.

"Why are you crying Buddy." He asked ,cupping his cheeks.

"Yun ijj hungry and unnie is lost." He replied in his baby voice taking glances at his hot chocolate that he had placed on the table earlier.

"Do you want this?" Joon asked, pointing at the full glass of chocolate that was still untouched by him. He nodded vigorously . Joon chuckled at his cuteness, giving him the cup.

Cupping the transparent glass in his tiny hands , he placed the straw on his lips as they automatically curved into a small pout. Admiring the cute baby on his lap he was lost. Carefully noticing his happy expressions after tasting the first sip.

It was after some time he came back to earth and began talking to him trying to imitate the Same baby voice as him, making the little boy giggle in happiness.

"You can finish it first, then we will find your noona okay?" He ruffled his soft black hairs that spread across his forehead.

He was enjoying his drink and talking about his mom at the same time. He was so small but his talks didn't fail to astonish Joon.

"My eomma works so hard. She loves me so much. I want to grow up and take care of my eomma because you know I don't have any Appa...." Namjoon could feel the sudden drop in his voice. He looked at him and a sudden smile appeared on his face. As if something ignited in his little brain.

" Can I call you appa? You are so nice and sweet." His voice held excitement and happiness .

The little boy didn't understand the depth of these words all his little mind could think of was he didn't have a father and for some reason he felt drawn enough to the stranger to call him Appa.

Appa. Only if he knew how much he craved to hear this particular word.

Namjoon stared at him blankly, uncertain of what he would reply as the boy stared at him with hopeful eyes.

"No Yun, I am just a stranger you can't call appa it anyone okay? It's a very special word , your mom wouldn't like you calling anyone appa." Namjoon explained.

"I know but you are so nice and handsome, I wish I have appa like you" he pouted

"Uhm I can't be your appa, but I can be your uncle! How about it?"

Before Yun could even say anything a girl came and abruptly picked him off his lap.

"My god! Yun how scared I was" The girl spoke in a terrified tone.

Now that he looks at her face, she was young, quite young to be his mom. Maybe she was his sister.

Then her eyes fell on him. She didn't look quite pleased with him .

Giving him a disgusted look she walked away.

"WTF ! Not even a thank you? Do I look like a thief to her?" He scoffed internally before glancing up to see the boy smiling at him . His cute smile managed to form an automatic smile on Joon's face too.

"Byee Choco Uncle!! " he shouted, making both Joon' and the girl's eyes widen. The girl turned again ,giving him another look rolling her eyes before walking away but he didn't even notice . He was busy trying to calm his racing heart which wanted to jump out right away.

"Choco Uncle?" Yun beamed from behind you, before running into Namjoon's arm. And to your surprise he too accepted him with the same excitement.

Choco Uncle? And then it hit you!
You remember Yun told you about that incident.

Mommi I met an uncle he was so sweet and nice,  he even gave me his drink. I was alone but he came to me. He was so nice.

You remember how happy he was telling you about the encounter he had with his chocolate uncle whom Jess thought to be a child thief.

"Yn actually I met Yun once-" Namjoon tried to explain with Yun still wounded in his arms.

"Yeah I know, Yun told me about the incident that day" You cut him off. "You know the best part? Jess Lily's sister took you as some child thief "

You saie Namjoon's eyes widened in shock. "DO I LOOK LIKE SOME THIEF?" He exclaimed.

It was funny to see his offended face.

"Actually she was scared she couldn't find Yun and when she saw you with Yun and also the drink she assumed you must have mixed something. She just watches too much criminal stuff" You laughed .

"Choco Uncle, what are you doing here? Is this your house?"   Yun chirped in his arms.

"Yes Yun, we are living in his house. I told you right that due to my work I can't live with you?"

Yun's expressions immediately changed, the soft smile on his lips was immediately replaced by a scared one.

"I..I am sorry sir! I will not call you that name again." Yun said, immediately getting down Namjoon's arms.

Namjoon frowned upon hearing the word sir.

"Sir? Buddy, why would you call me that? I am your Choco Uncle right?" He softly asked, crouching down to his level.

"No no I can't call you dat now. You mommy's Boss" Yun pouted, shaking his head vigorously.

Then you realised why he said that. Normally you never take Yun to your jobs other than the one at library because you are  alone there and he doesn't make any noises. But one day Jess had to go somewhere and no one else was at home so you had to take Yun with you to the cafe you worked at.

You didn't work alone there, you had a few colleagues and a manager. Although your colleagues were very sweet and kind, they were happy to meet Yun finally but your manager was salty about bringing Yun.

He was a very rude and an irritating man. When Yun called him Hyung he got offended for some reason and yelled at him.

"I  am the boss here! I ain't your hyung you piece of shit. Don't you dare call me that. Call me Boss like your mom does"

God knows I don't know how people can be so insensitive to kids. Even if that job paid quite an amount, it was your last day there. You couldn't stand in a place where they insulted your son.

"First thing, I am not your mom's boss buddy, she is a friend to me who is doing a huge favour to me okay? And second even if I was her boss it wouldn't matter. You can call me what you did earlier but wait... Don't call me uncle now that I think of it, doesn't it sound too old? You can call me hyung."

Yun's face beamed with happiness.

"Omg! You are shoo niceee" he giggled before jumping back into his arms.

Namjoon looked at you and gave an assured look which you returned with a soft smile.

Your heart was content knowing now Namjoon didn't mind Yun's stay here.

Knowing he is in safe company, you left Yun downstairs with Namjoon to take a bath and get dressed. But before that you didn't forget to have the apple Namjoon was trying to cut. Yesterday was a disaster for you . In everything that was going you completely neglected yourself. You didn't have any food ; you drained your eyes crying and not to forget the amount of stress you had.

It was really unhealthy for you during this stage, last night this thought did strike your mind. Namjoon has been such a great friend, it was your responsibility to take care of yourself and keep the baby healthy. In your problems you can't let the baby suffer.

His health is completely dependent on you so this morning you swore to take care of Yun as well as yourself.

While heading down you could hear giggles of your Son, the beautiful melody that your ears had been Missing for months.

"No no hyung like this. You are doing it wrong!!" Yun facepalmed before taking something which looked like a piece of puzzle from Namjoon's hand.

Once Fully in the living room; you saw there was a half done puzzle laid on the table and some pieces kept around. That wasn't all, there were some bags containing groceries . Looks like ajumma is back .

"Mommiiee" Yun waved, calling you to see the masterpiece under progress.

"See choco hyung bought me this'' he pointed at the box of puzzle that was laying on the floor "and...." He ran to the table where grocery bags were kept "this.. thiss and all this' ' he giggled showing you multiple packets of snacks, chocolates and a few colouring books.

"Namjoon? When did you buy those?" You exclaimed looking at the bags of items you hadn't noticed yet.

"Ajhumma had to bring some groceries so I asked her to bring these too , since Yun will be here he should have something to play with I thought or else he will get bored " He shrugged still focused on the puzzle.

"But Namjoon it's so much you didn't have to" You argued

"But I wanted to okay?" He gave you a look before joining Yun back on the puzzle.

Before you could argue the bell rang, gaining your attention.

"Noonaa!!" Yun beamed once Lily walked in with a bag containing Yun's clothes and essentials.

"Aww my babyy..how are uh?" She cooed, giving him a few pecks.

"Good! See hyung bought me so many gifts" He chimed showing everything that was laid on the table.

Lily smiled to herself before giving you a "I told you" look.

So this morning you were kinda freaking about Namjoon's reaction so you called Lily, you even had to ask her to bring Yun's essentials. You weren't sure how things would go so asked her to come personally and not to send a driver because in case things didn't go well and Namjoon didn't like Yun's presence you could send him back with Lily but she was sure and that won't happen.

"Come baby let me give you a bath okay? After today your mom would only  be the fortunate one" Lily pouted.

You took them both upstairs to your room, after showing Lily the bathroom and other stuff such as towels etc you joined Namjoon downstairs.

"Yn.." Namjoon called out rather nervously. You just hummed, arranging all the chocolates and snacks in the kitchen.

"I understand why you thought that I would not like Yun's presence, I can't blame you for thinking that way after my attitude the initial days  but trust me I am really happy to have Yun around. I can't express how fond I am of children and Yun is such a precious child, in so little time I already feel so attached to him. You don't have to think about anything and I am happy to have Yun here for as long as necessary. Please don't hesitate about this in future. "

You nodded. "Thank you Namjoon, this really means so much to me"

*Doorbell*

"I will get it."

"Tae--?"

You hadn't even finished your word when you felt yourself being held in a bone crushing hug.

"Yn..." He whispered.
