Jungkook was left in frozen and shock in his spot on how much Karina had changed after he transferred to another school years ago. Karina on the other hand came out of the building with her nunchuks hanging on her shoulders while holding on to them. Jimin took out an headset that as a mic attached to it to communicate Karina.

"Karina you got company". Jimin said to Karina through the mic.

"Roger". Karina replied as she touched her headpiece on her ear as she chew a gum.

A group of thugs came and spotted Karina standing there. The group of thugs are in fact men, they all whispered to each other with a evil chuckles as they walked towards her, Jungkook on the other hand met up with Yoongi, Amber, Taehyung & Irene with the girl who was frightened to death while crying silently under Irene's wing.

"Yah where's my sister?" Jungkook asked them.

"Over there". Amber replied as she pointed the location where Karina is.

"Is she crazy?!" Jungkook exclaimed as he was about to make a step forward but Yoongi stopped him.

"I wouldn't do that if I were you Jungkookie". Yoongi said in his cool tone.

"But..." Jungkook was about to protest.

"But nothing, let Karina handle it". said Irene.

"I'm staying here you guys can all go in". said Jungkook.

"Okay man but whatever you do... don't get in her way". Taehyung pats on Jungkook's shoulder.

"Okay so I have to watch from here while those men touch her?" Jungkook replied as he asked Taehyung.

"Yah she's not the type to let guys touch... you're seeing her as the sweet girl you once knew". Yoongi sighed.

"She still that sweet type of girl I've always known". Jungkook replied.

"Well that was the past". said Amber.

"She's really ruthless when she fights, trust me she shows no mercy". said Irene.

Meanwhile the thugs were all surrounding Karina.

"Hey there pretty thing". one of them greeted making Karina have a disgust face.

"Wanna play with us, promise we won't be rough". said another one as he lick his lip because of Karina's beauty.

"Over my dead body". Karina scoffed.

"Yah don't play hard to get we already let one get away". said one ugly man.

"Play hard to get?" Karina asked while sighing.

"Looks like little miss is not going to cooperate with us boss?" said a scruffy looking one.

"Yes well I want her all to myself, get her!" said the boss.

"You the boss girly". said one of thug.

"Girly?" Karina tighten her fists.

"Choose the hard way or the easy way?" another thug asked her making her even more angrier.

Karina remains quiet making the group of thugs become impatient.

"Looks like we're going to do this the hard way". said another thug man who looks like that has some teeth missing.

They group of thugs all smirked and walked closer to Karina... As one of them was about to grab her arm, Karina was quick enough to kick him on the chin, the others tried to grab earning bruises and cuts from Karina. Jungkook stood there speechless on how vicious fighter his step sister had become. Karina was now face to face with the main boss of the thugs who was clapping his hands at her impressive fight skills.

"My my my". the boss of the thugs chuckled evilly.

Karina held onto her nunchuks tightly as her eyes glared at the man in front of her. The older man suddenly charged towards her and Karina manage to nodge the main mob's fists whereas she was quick enough to swing her nunchuks that landed to the man's head. The older man got even angrier than before and took out his gun to shoot her but he failed because Karina grabbed the man's arm where the gun and simply twisted his arm making him cry out of pain. Jungkook didn't moved a muscle as he watched all horrified on how Karina fights he wanted to stop her but he remembers what Taehyung told him.

The man was on the floor already and tried to reach for the gun with the other arm which was in a good state but Karina picked up the gun and gave the older man a cold expressionless stare.

"Who are you?!" the man demanded.

"I'm the grim reaper". she smirked.

The man looked at her carefully and realized who she was and his weak defeated body started to shiver in fear and his thugs got up all bloody, bruised and were limping to get their boss and left the school leaving Karina. Jungkook then was able to move and went towards his sister.

"Have you lost your mind?!" he bursted.

"Huh? What are you on about?" Karina asked her brother in disgust.

Jungkook didn't reply back but he instead kept silent. Karina and Jungkook went back inside the school building where the others were with the frighten girl, Karina walked up to her.

"Are you okay?" Karina asked her.

"I don't how to thank you". the girl cried out.

Karina smiled at the girl and patted her head.

"Don't worry you're safe now". said Karina.

"I think someone should take her home". said Jin.

"Great idea". Yeri replied.

Everyone all turned their eyes towards Jungkook who was standing next to Karina.

"Why are you all staring at me for?" Jungkook asked all confused.

Jungkook's eyes widen when he realized why they were all looking at him, he then looked at the poor girl who was shivering in fear and deeply sighed.

"Fine T.T I'll do it". he replied all defeated.

"I'll come with you oppa". said Karina.

With that Jungkook, Karina and the girl went towards Jungkook's car, Karina got her school bag and sat next to the girl in the backseat and Jungkook then starts the car and drove off to the girl's house safely.
