Deoksim was in her room panting heavily because of the spicy dish she had for dinner.It was really hard for her.Her stomach was burning. She plopped herself on the bed and rolled here and there.

"Ahhhh!It's so hard!"she whisper yelled and and tried to eat the pillow to vent out her anger and the pain."Kim Taehyung,Kim Jungkook!I will never let this slide!Ahh!omma!!"

Just then she heard a knock on the door.She calmed herself down and tried to look cool.She went to open the door.

Jimin was infront of her room holding a cup of ice cream.He didn't look at her eyes.He cleared his throat.

"Here.Your desert.It will cool you down"he tried to use his cold voice not wanting show that he cared for her.

"Aww Chimin,you care for me huh?"She decided to tease him a bit.

He widened his eyes and scoffed.

"Ani!why would I?It's the desert. J-Jin hyung wanted me to give this to you.Nothing else"..."And It's Jimin not chimin you dummy"

Deoksim smirked.She determined not to do any prank on him.She took the ice cream cup.

"Thanks Chimin oppa!"She chimed cutely and closed the door before the male could utter any word.

Jimin widened his small eyes again.

"IT'S JIMIN!"He shouted and turned around to leave but a ghost smile plastered on his lips.

"A sister?is it a good idea?"he muttered to himself but instantly shook off his thoughts remembering his lost sister."No no.She can never take my sister's place"

It's midnight. Everyone was asleep. Oh that's what they thought. Deoksim got up from her bed and messed her hair.

An evil smirk was plastered on her face.

"Kim Seokjin,here I am coming"

Seokjin was sleeping peacefully when he heard a knock on his door.At first he ignored it thinking he might be dreaming but groaned when the impatient person didn't stop banging on his door.He stood up lazily and went to his door.

He opened the door only to scream his life out.

"Ahhhh!"

The person with a messy hair quickly removed her hair from her face and giggled.

"Oppa,It's me!"

Jin placed his palm on his chest trying to calm his breathing.

"Aish!You startled me!"...."what do you want?"he asked rubbing his chest.

"I want to go to the kitchen.To drink water.Do I get the permission to go?"she asked innocently.

Jin looked at her in disbelief.

"You woke me up just to ask that?!"

Deoksim nodded innocently.

"Yes.It's a rule YOU made for me"

Jin sighed and waved his hand.

"Okay.Just go already."

After 15 minutes.

Seokjin woke up again because of a knock. He groaned and went to open the door.

"What is it?"he asked the innocent looking girl infront of him.

"I'm hungry.Can I go to the kitchen?"

Jin sighed and nodded lazily.

After 30 minutes

"Jin oppa,I'm thirsty again"she whined like a baby.

"Go go"

After another 30 minutes

"Oppa,I want to eat ice cream"

"Oppa,I forgot to drink water"

"Oppa,I forgot to bring my phone which is in the kitchen"

"Oppa---"

"Hey stob it!"Jin screamed out of frustration."GO AND LIVE IN THE KITCHEN!IF NOT YOU CAN EAT THE WHOLE KITCHEN!LET ME SLEEP YOU BRAT!"

Deoksim pouted.

"Oppa but the rule--"

"There's no any rule like that!Leave me alone!"

Deoksim grinned in victory.

"Thanks oppa!"She chimed.She ran away shouting "SARANGHAE JIN OPPA!"

Jin scoffed hearing it.

"This brat really knows how to get in my nerves"

Deoksim jumped on to her bed and chuckled remembering Jin's red angry face.

"1st mission.Clear."She sighed.

Next day came.Deoksim didn't sit for the breakfast.She quickly got ready to leave for school. She remembered what she did last night and smiled evily.

When she was heading to downstairs, she saw Jungkook pouring milk in to a cup for himself.She definitely knew that he will be the 1st one to open the milk bottle.

Taehyung and Jimin were standing infront of him while talking about school stuff.

Jungkook took a gulp before spraying the milk all over Taehyung's face.

"What the hell--"Taehyung yelled in disgust.

"Hyung,this milk!It tastes too salty!"Jungkook cried and spit out saliva to remove the disgusting taste.

Jimin was surprised. But his mouth went agap realizing who did it.Other two also realized it.Jungkook clenched his jaw.

"Bye bye Felicia!"Deoksim's loud voice was heard.

They saw Deoksim running out of the mansion laughing so hard.

"Kim Deoksim!!!!"Jungkook and Taehyung shouted in unison.

Even before a second pass,they both started to chase her leaving Jimin dumbfounded.

"Yah!kids!Where are you running?!"Jin shouted coming out from the kitchen.

Jimin shook his head and ran after them.

"Yah!Jimin-ah!your breakfast?!"

The three maknaes were running in the streets to catch their mischievous step sister.

"Yah!stop right there!"Taehyung shouted trying to catch his breath.

"You little bratty cannibal!Stop right there!"Jungkook shouted from the top of his lungs.

People in the streets were  looking at them weirdly.

"Catch me if you can!"She screamed.

Taehyung and Jungkook were chasing her like their life depend on it.Without knowing they were heading to their school without their car.

"Fucking hell!"Taehyung cursed when he stepped on dog poop but didn't care to stop to clean his shoe.

"Kim Deoksim!you better save yourself today!Cuz hell is waiting for you!"Jungkook screamed while running.

"Guys!Let's stop!Let's catch a bus atleast!"Jimin whined trying to keep up with them.

They almost forgot that their brother Jimin was also running with them.

"No!she will escape!I'm going to bury her alive today!"Jungkook screamed. It wasn't the milk which made both Taehyung and Jungkook angry.It was their desperate wish to make her life a hell for coming to their life.They were taking every little mistake of hers to torture her.But little did they know,who is getting tortured right now.

After running for a while,they reached their school.

Jungkook, Taehyung and Jimin stopped and panted heavily.

"I'm going to--I'm going to kill her"Taehyung muttered trying to catch his breath.

Deoksim also stopped and looked back.

"Yah!You old hags!did you catch me?!"she shouted trying to provoke them.

She did an ugly victory dance to mock them and ran inside the school building.

"Bitch!you are a dead meat today"Jungkook muttered and tried to run after her.

But all three of them stopped hearing someone clearing their throat.they turned to around.

It was their discipline master.Mr.Lee Hyun joon.He is known as the grim reaper in the school.Build up body with massive muscles were no joke.

"Gentlemen,where are going in this fine morning?"he asked with a fake nice voice.

The three trembled badly on their spots.

"T-To our class"Taehyung stuttered looking down.

"Like this?"Mr.Lee pointed to themselves.

Jungkook's shirt wasn't even buttoned fully.Taehyung didn't even have his tie.To add more,they both didn't have their school bags.Only Jimin was perfectly fine.

Jimin suppressed his laughter and bit his lip.

Taehyung and Jungkook gasped remembering how they ran after Deoksim without even getting dressed up properly.

"Jimin,you can go to the class"Mr.Lee ordered.

Jimin nodded and left right after that.On his way,he looked back and waved the youngers teasingly and ran away.

"And you two!"Mr.Lee snapped making both siblings startled.

"Kneel down infront of principal's office!"
