AN: Okay, this is really exciting for me. I came up with this idea a month ago, and it really made me happy inside because it's pretty original (I haven't read fics before like this). So here's what's happening:

Dr. Jack Napier is a young, brand new psychiatrist who has just started working at Arkham Asylum. Then he meets the beautiful, charming, and INSANE villainous- Harley Quinn. She is fascinated but lethal and Jack is instantly captivated by her.

So basically, it is Mad Love FLIPPED. Harley is Joker and Joker/Jack is Harleen Quizel. Crazy huh? But I figured it would be very fun to write, so I'm doing it.

Disclaimer: I own nothing, everything is DC's property, sadly enough.

Enjoy!

Dr. Jack Napier had just graduated Gotham University at the top of his class, and was on the road to success. His scholarship had ensured that he had no debts to be paid for college, and he already had a job working at the one of the most infamous asylums in the country, arguably the world. Gotham was filled with its fair share of lunatics, and they were all held in captivity in the same place- Arkham Asylum.

Jack got out of his car clutching only a briefcase. At the entrance, an African-American woman smiled at him.

"Hello. Are you Jack Napier?"

"Yes, I am." He nodded politely. "And you are…?"

"Dr. Joan Leland. I'm going to be your mentor here at Arkham Asylum. Is it your first time here?"

She made it sound like it was a restaurant for Christ sakes. "Um, yes, we went on a field trip of sorts last year. It made a lasting impression on me." He grinned, attempting to look friendly. Jack wasn't the most social of people, but he really did try. He preferred to keep to himself. It was safer that way.

Joan beckoned him towards her, turning as he followed. "I think you're going to do fine. Just don't stir up trouble with the other doctors or guards, and everything will go well. Hopefully you won't want to quit after the first month or so." She teased, and he laughed. Joan seemed like a genuinely nice person, he decided, and genuinely nice people were always good to have around. He had been nervous, of course, because this was his first job and he still had a lot to prove.

Psychology was something that had fascinated him as a young boy, though he hadn't known exactly what the term had been for the subject that he mused over constantly. He wanted to help people, but unlike a lot of his classmates, he didn't just seek to fix physical wounds. He wanted to heal the mind. His parents often chided Jack when he would express sympathy towards 'evil' people who had obviously just gotten dealt a bad hand in life and chose to react in a way that didn't seem too unreasonable. So he'd studied hard, and gotten spectacular grades. Then he got into Gotham University and continued studying diligently and stayed away from partying and drinking and didn't run with a bad crowd. Of course, that was because he didn't run with a crowd at all. But that was fine with him.

"I'm ready." Jack Napier declared.

"Since you are a male doctor, you can come down here. Women generally aren't allowed because some of the men down here were previously sex offenders and well, a female doesn't do much good for them."

He nodded. "When will I be able to work with higher level patients?" He asked, a curious look on his face. He was eager to speak with the more insane of this bunch.

"I'm not sure. Probably soon, so don't worry."

Jack's head turned sharply when he heard it. There was a light, musical sound floating down the hall, slightly high-pitched. Without any regard for what Joan was saying, he began to tread slowly towards the source of the noise, which was at the end of the long rows of cells containing a variety of inmates, including a red-haired woman tending to a plant, and a short, balding man licking the glass, until he finally reached his destination.

When he caught sight of the inmate inside the cell, he had to make a conscious effort to keep his jaw from dropping. A young, beautiful woman stood inside. The first thing Jack noticed was her skin, a delicate ivory shade. Well, it was white, like a bleached bone. She had pale blonde hair cascading past her shoulders, and he realized it was tied back into two pigtails. She was very short, at least a foot below Jack's height, and he could tell she had a curvy body, despite the ill-fitting uniform that all patients wore. Her face was round, and youthful, and her bright red lips were full, curling into a small smile. He would have thought she seemed childish, if not for the intense, burning stare coming from her deep, baby blue eyes.

He was stunned when he realized he had given her a slight wave, which she now returned with a delighted look on her face. A second later, Joan was beside him, lips pursed as she gently grabbed his arm and pulled him away.

"That's Harley Quinn." She hissed when they were further away. Dazed, Jack looked at her.

"I know. Such a complex case…" He glanced back down the hallway with a hint of a wistful expression. "She would be one hell of a case!"

Joan's face was disbelieving. "Jack. I'm not sure if you're ready to handle that. I mean, she's the craziest of the bunch."

Jack shook his head and laughed. "Oh, I know, don't worry. But I like a challenge."

Dr. Leland laughed as well, shrugging her shoulders and throwing up her hands. "Who knows? You seem like you're going to be a great doctor. We need great doctors on cases like these." She started walking towards the elevator. "Come on, I'll show you the staff's break room!"

A few hours later, once Joan had taken him to where he would work then left him alone, Jack came back out of his office to stare at the title- Dr. Jack Napier, M.D. A smug look appeared on his face, and he puffed out his chest slightly, grinning.

"Way to go, Jack!" He congratulated himself as he went back inside. "Can't believe I'm finally here!" He continued walking towards his desk, but stopped abruptly as something caught his eye.

A piece of paper balanced precariously on the edge of his desk, and Jack's hand shot out to grab it. He looked down at the note, brow furrowing in confusion. The 'O' shape his mouth had made now slowly turned up into a smile.

4-782-11 Come down and see me sometime, cutie! xoxo –HQ

Jack's eyebrows raised as he realized the digits was Harley Quinn's cell number.

"What have I gotten myself into?" He asked with a chuckle.

AN: Did you like it? It was kind of odd, yes, but I just thought it'd be fun! Of course, just let me know(:

Thank youuu xoxo
