Summary
Modern AU Prompt: Hospital Medical Drama / Romance
The first time Sadie laid eyes on him, she thought he looked like his place was on a battlefield. Not a Hospital ER. He was in the middle of doing chest compressions to an unconscious patient and barking orders like a drill sergeant.
“That there is Dr. Arthur Morgan,” their senior resident says to her and the rest of the intern group. “He'll be your Trauma attending. He’s in charge around here. I highly advise you don’t get in his way. Because it will not end well for you.”
And Sadie believed that. But she also had the nagging feeling that she will gravitate towards that “trouble” on legs whether she likes it or not.

Summary
Charles Châtenay, Arthur's old artist friend whom he helped back in Saint Denis in 1899, has invited him to an art exhibit in New York. As he recalls, that man's "art" was called too provocative by the commonfolk.
Back in the day Arthur found it entertaining when people were screaming for Châtenay's head to be on a pike, but now that he himself is tied to a woman—and Sadie Adler no less—maybe he better gauge his own reactions or else his girl will shoot a bullet into his ass.

Summary
Arthur usually gets haircuts from a barber. But ever since he got a partner, what’s the point of spending money if he already had an extra set of hands that can use a pair of scissors just as well as any barber can. Only problem is— that partner in question is literally Sadie Adler. His woman. His love. And apparently his body can’t help but “react” when she’s all up in his space.

Summary
Modern AU Prompt: Gym Regulars Meet Cute
Arthur is a regular gym buff who frequents at a well-equipped local gym called Iron Haven. He's known as "the mountain who squats mountains." Trains everyday. Lifts weights like nobody's business. He's huge and jacked, but never an asshole. Respected and lowkey adored by the regulars. Old ladies think he’s a sweetheart, bros think he’s a legend. Flaws? He is seriously lacking in the flirtation department. Secretly romantic but has never had the guts to actually ask anyone out. Lives alone, eats protein and loneliness for dinner.
Enter Sadie Adler. Sharp, sassy, independent. Has a biting wit and zero tolerance for BS, and is a total fitness nut too. When Arthur first saw her, he was already awe-struck. Didn't even know her name at first—just refers to her in his mind as “the feisty yoga girl” who smells like citrus and wrecks his soul every time she walks by in those yoga leggings.
