Special Kind of Crazy

Present Day - Seoul Mental Institution for the Criminally Insane

warning: in this, taekook are NOT good people. At the start, Taehyung is good but later on he becomes much like Jungkook. and you might hate seokjin too, so sorry not sorry.
Also, please note that murder is not okay and this doesn't glorify it or make it seem like it's a good thing to do, it's simply a piece of fiction. there's a disgusting amount of nicknames as well.
another note, jungkook is a sadistic fuck but taehyung is masochistic, every sexual interaction is consensual between the two!

The Joker – Jeon Jeongguk/Jungkook
Harley Quinn/Quinzel – Kim Taehyung

Present day – Seoul Mental Institution for the Criminally Insane

Taehyung tapped his card against the scanner, heading inside the building and bit his lip anxiously, hearing distant screams and noises coming from the cells in Block D.

He went over to the main office, knocking on the door and waited for a response. "Come in!" Shouted the man from inside. He opened the door and saw Seokjin propped against his desk, holding a thick file in his hand, flicking through it mindlessly.

"You wanted to see me?" Taehyung asked, clearing his throat and adjusting his glasses. Seokjin smiled lightly, walking closer to him. "Indeed. I wanted to discuss a new patient that I'd like you to analyse. You may know him as The Joker, yes?"

Taehyung felt his eyes widen massively at the mention of the criminal's name, nodding instantly and peering down at the file gripped tightly in Seokjin's hands.

"O–Of course, Sir. I've seen him on the news."
 
"Great! Here's his file, but don't let him fool you with his tactics. He's done this to other doctors in the past. He makes them believe that they've changed him for the better and then he turns on them, showing his true colours." Seokjin said coolly, his voice like ice and his attitude changing instantly than it was before.

Taehyung gulped and nodded slowly in response, "I'll make sure he won't, sir."

Seokjin grabbed another document from his pile and stuffed it into the already overflowing file and passed it to Taehyung. "Good, I'll ask for an update in the next few weeks or so. He'll be brought to your office shortly."

Taehyung clutched onto the files and made his way out of the main office to head to his own, He sat down at his desk and opened the file to flick through it, feeling shivers shoot down his spine the more he read about the criminal.

The contents contained very little information about The Joker's real name or his background such as his childhood. It remained unknown and only mentioned his many crimes over the years.

After a while of sitting in silence whilst reading the file, he heard footsteps coming from the distance and saw as the doorknob twitched and revealed several officers holding onto a noticeably young man that had shackles around his wrists and feet, restricting him of movement.

Taehyung studied the man further, noticing his arm sleeve decorating his left arm, and a slight gash on his lower lip. "We'll be outside, Doctor. Let us know if something happens." One of the officers said, shoving the man over to the chair before the group left the office.

Taehyung bit his lip nervously, unsure of what to ask as they sat in silence for a few minutes until a scoff came from the man. "Are you like this with all of your patients? Just sit in silence?" The Joker said, a teasing grin appearing onto his face.

"Oh, right, sorry. Could I ask what your name is? So I know what to call you?" Taehyung asked, looking up from his file and at the male directly.

He noticed how his facial expression changed dramatically and the grin that was once there had disappeared off his face. "Pretty, pretty.. I don't think I should tell you." The latter titled his head to the side, his nose scrunching up.
