(P.s: Inspired by the X-man series. Kookie is like the Wolverine here. With a few twist of course. )

Jungkook groaned in pain when his body was thrown on the cold ground as if he was nothing but a rag doll. He was half conscious to register what's going on but the sound of the metallic door violently closing made him flinch slightly.

"Fuck." a silent curse escaped his lips while he struggled to get him. The twenty one year old had his arms botched in purple and green marks from all the syringe they forced inside his skin and the experiment they ran on him. His skin was pale from the lack of sun since he is always kept inside the "Cell".

Due to the drug they kept using on him,  his abilities and the animal like adaptation of his body were slowed down, especially his ability to heal . Every time he'd try to extrudes his claws they'll cut through his skin but it won't heal immediately and will cause him pain that's why he stopped extruding them until it's his time to escape. He had to and hell he will. Those motherfucker will face the consequences of holding him captive sooner or later.

Right now he just needs some sleep and maybe he'll wake up in the middle of the night to exercise a little more.

"Mutant, your food." one of the "Workers" there said while pushing a tray from the small opening in the door but didn't get a curse like usual.
"Number 88 Mutant you're awake?!"
Still no reply.
"I am gonna make sure they'll give you a good electric shocking you bitch!"
Still no reply....did he escape?! No way in hell.
He rose his eyebrows in confusion while struggling to open the metallic door,  his eyes winded in horror at the sight.
Number 88, formerly known as Jeon Jungkook,   was laying in a pool of his own blood,  both wrist cut. He probably used his retractable claws to do so.
He approached the body...there was no heartbeat and his chest wasn't moving. The man quickly uncuffed the bloody wrist and tried to stop the blood.
Jungkook was their most important experiment. They can't afford to lose him.

"Emergency!! Seohan is speaking, number 88 is-!" before he could continue speaking through the device he had Jungkook's claws were already half way through his throat.
The Mutant threw Seohan aside then ran out of the cell,  he can already hear the sirens and alarm going on.

Earlier,  Jungkook extruded his claws despite the pain and made small cuts over his wrist, his healing ability was enough to keep him alive. Having an animal like adaptation was one of the reason he could play dead perfectly.
So with the blood from his wrists,  his half opened eyes and frozen body that guard believed his little play .

While running,  the Mutant saw a room he never noticed before. It was locked from the outside. He ccould hear small whimpers coming from it...is it possible that they have another Mutant here as well?

Using his claws,  he broke the lock and kicked the door opened. His doubts were real. There was another person on white bed , unconscious, with a white cover on top of him.
Jk carefully and slowly approached...it might be a trap for all he knows.

He doesn't have time at all since he can hear their footsteps approaching but he can't just leave another Mutant like him like that. Mutant don't deserve to be treated like a plague,  lab rats,  filthy demons..he really hated humans.

The man was naked under the cover,  but Jk noticed all those purple marks all over his fragile body.  His rosy plump lips were dry,  his hazel brown hair was drenched in sweat,  probably from exhaustion...God knows what those monsters tried on him.
He was whimpering in his sleep. Pain of course.

Without much thinking, Jk wrapped him in the cover and threw him over his shoulders then ran again.
He was going to escape alone but he wasn't planning on leaving another mutant like him behind to suffer.

Jk dogged a lot of mad bullets they shot toward them,  he jumped from place to place,  slit a lot of throats using his claws while pushing the guards aside. Finally after what felt like a ten years of running through mazes with a weight on his back. Jeon Jungkook escaped the facility that held him capture since five years.

Currently he was in the middle of the wood,  trying to start a small fire to warm himself and his fellow mutant whom was still unconscious.

"Fuckin shit!" Jk shouted throwing a tiny branch away,  accidentally throwing it at the other's head.
The man slowly started wake up. He didn't panic or flinch even after seeing where he was and Jungkook whom was definitely a stranger. But once he noticed his bare state with only a dirty cover on him he blushed and hid his face.
Jungkook smiled a little then took off his not so new shirt and gave it to him. At least Jk was wearing a pants and didn't really needs to hide his chest while his fellow was naked from head to small toe.

"So...you're a..mutant as well?"
He nodded after wearing the shirt which luckily reached till his mid thighs...better than nothing.

"I am Number 88- screw that. I am Jungkook. Jeon Jungkook. And..we escaped the facility. More like I escaped while carrying you on my shoulders...sorry if you have a headache..cause while running..I accidentally hit your head against..five to ten trees."

The male chuckled a little,  the sound was really adorable that Jk felt something in the pit of his stomach.
He then stood up and out of the blue hugged Jungkook.

"O-okay...so what's your name cuddly mutant?" Jungkook asked in awe of the man whom still hugging him. 

He's weird.

He backed away,  brought a finger to his lips then made and "X" with his hand.

"You can't talk?!"

He nodded.

"Oh...sorry...must be because of the needles they used to inject you with."

He nodded again and Jk clicked his tongue in annoyance.
Stupid humans.

But the man grabbed a branch and started writing on the sand beneath them.

"Kim Seokjin. Thank you for saving me."

"Let's find somewhere safe to sleep Seokjin. We still have a very long way to go."  Jungkook said while extending his hands and Jin gladly took it.

They walked,  more like half ran, with their fingers intertwined toward somewhere to hide till the morning.

Together.  They ran.

(Not?) The end :3
