I knocked on the apartment door a few times until it opened, revealing nobody.

Where is Jimin?

Am I in the wrong apartment? Was he kidnapped - okay, I think I'm overreacting.

I looked down, only to see a little kid.

"Who's there?" Jimin's voice echoed from the kitchen.

"Ooh, a girl," The little boy grinned as I entered the apartment.

I crouched down and patted his head, "Hi, what's your name?"

"My name is Park.. Jae.. hyun!"

I chuckled at his actions.

"What's your name?" He asked back.

"I'm Lee Saerin," I smiled.

"Is he your nephew?" I walked towards the couch and whimpered when my foot landed on a lego brick.

I looked down and there were lego pieces. Jaehyun followed me and grinned. "Noona, let's play!"

I turned to Jimin and he looked at me with an understanding smile, "Noona is tired, Jaehyun."

He frowned and sat down on the carpet, playing as if he had no energy left.

"Actually.." I started and sat on the floor across him. "I used to play legos too!"

"Oh, right! Do you remember how we used to play this every summer back then?" Jimin butted in while taking a short glance at us since he was busy cooking.

"Yeah, we used to build lego houses on the sand!" I remembered the times Jimin and I met every summer since our parents were acquaintances.

"Really? Can you teach me?"
His eyes lit up while raising a block of lego.

"Sure!" I smiled and picked up a few blocks, building a little house.

Jimin turned off the stove and sat on the floor beside us, "Can I join?"

We wasted hours on playing lego, continuously laughing because of Jaehyun's gestures.

Jaehyun giggled as he finished his masterpiece - on Jimin's face.

"Hey! What did you draw?" Jimin playfully took the marker from the younger boy.

He chuckled in mischief without replying. I also laughed at Jimin's face.

"Wow, you look like - an ahjussi!" I said and Jimin jokingly glared at me.

He took out his phone and looked at himself using the front camera. "Waaaah!"

Jaehyun and I high-fived while cackling at him.

Jimin slowly walked towards us, a playful smirk plastered on his face.

He pinned my shoulders towards the floor and I closed my eyes, feeling the tip of the marker go around my face.

Now all I could hear was Jimin and Jaehyun giggling quietly.

After a few minutes, they were done with their mischief and I opened my eyes, only to see Jimin's face inches away from me.

We were both flustered as Jimin quickly sat up, and I did too.

There was slight awkwardness in the air until Jaehyun broke it.

He yawned, "I'm sleepy."

I tucked him in as Jimin watched, sitting on one side of the bed.

"We'll stay until you fall asleep," I muttered silently and smiled.

After a few minutes, Jaehyun just kept shifting around until he let out a sigh.

"I can't sleep."

"Uh.. what does your eomma do to make you sleep?" Jimin asked, caressing the child's head.

"She sings me to sleep," He whispered to Jimin.

"Can you two sleep with me?" He suddenly mumbled, and Jimin and I looked at each other awkwardly.

"Uhh.." Jimin hummed. "I think—"

"Jimin will sing you to sleep, while I'll stay here beside you," I layed next to him and he cutely smiled, engulfing me in a hug

I just love little kids, they make me forget about reality of grown ups.

Jimin layed sidewards on the bed and cleared his throat before singing.

Amugeotdo saenggakhaji ma
Neon amu maldo kkeonaejido ma
Geunyang naege useojwo ♪

Nan ajikdo mitgijiga anha

His voice was like serenity in chaos. Soft, soothing to my ears. I closed my eyes, listening to his smooth melody that calmed my soul.

I felt my entire body relax until I drifted into deep slumber.

Jimin's POV

In the middle of singing, I glanced at Saerin but she was already asleep.

I turned my attention to Jaehyun who was still innocently staring at me with his doe eyes, not a sense of sleepiness in his eyes.

"Can I tell you a secret?" I whispered.

He nodded and scooted closer to me, eagerness visible in his expression.

It's impossible to make this kid sleep.

"Promise me you won't tell anyone, even Saerin noona.."

Jaehyun giggled silently and nodded, "Promise," holding out his pinky finger which I linked mine with.

"Don't you think Saerin noona is beautiful?" I smiled.

"I think Saerin noona is really~ pretty, samchon..." He emphasized the 'really' and then paused and slyly smiled at me, "do you like saerin noona?"

"I don't like her Jaehyun," I sighed.

I pursed my lips, taking another quick glance at Saerin who was probably dreaming.

"I love Her."
