Honestly idk yet (from ao3)

A Therapist and a Physician walk into a bar

Yukina awoke with a start. Shit. She had slept through her stop. She decided to get off at this stop and find another route to her desired destination.
    "Next stop: Yokohama!" The voice in the intercom chimes a few minutes before the train pulls into the station. Yukina arrives at the familiar city where the legendary Armed Detective Agency resides. She had planned just to book the next ticket to her actual station but as she got up to the booth, she found that the route had been blocked. An explosion was set off on its designated road. Thankfully, no one was hurt. The news made her remember something: the Armed Detective Agency wasn't the only group in this city. Looking around, many other people wanting to commute on that route seemed much more annoyed than alarmed at the attack.
   Just how normal of an occurrence was this? She thought to herself. Yukina decided she shouldn't stay any longer, it would be better to find a bus or cab to another train station past the wreckage. Yes, that is what she will do.
Looking at the sky as she exited the station, she realized the sun was quickly setting against the horizon, painting the sky a warm palette of pink and orange. It would be an enjoyable view if it didn't signify that night was falling. If blowing up railways happened in broad daylight, Yukina didn't want to know what would happen under the cover of night. Wandering down the street, she ultimately decided to look for a bus stop since she wasn't too familiar with places to call cabs. On the way to the nearest one, (following her GPS) she found that her path was constantly making her take twists and turns that just made her get lost, and soon enough, the sky had turned an inky black.
"Stupid Google Maps!" Yukina cursed under her breath, realizing she ended up in a less-than-well-lit street. Rounding an alley corner, she heard what sounded like crashing, cut-off screams, and bodies thudding.
    Oh hell no. Was all the woman could think before she almost started bolting in the other direction. Her heart was racing, and her chest pounding almost in sync with her feet on the cracked pavement, almost tripping several times in her high heels. She almost didn't notice a flash of fiery red hair from her left peripheral vision. Almost. It had only been there a moment, but she was not one to miss such a detail.
Adrenaline dying down and drenched in a cold sweat, she skirted to a stop in front of a well-lit bar, half her mind remembering to compose herself before walking in, four-fifths of it still reeling from shock, and a small part still logically intact telling her she was entering a bar where no one would look twice at someones slightly disheveled appearance.
"What can I get for you?" The bartender asked as Yukina sat down at the counter seeing it was the most sanitary-looking option.
    "Amazake." The bartender nodded and poured her the sweet alcohol. Taking a sip of the heated drink, she contemplated the sheer chaos she went through today. Thinking back, wasn't Natsuko from this city? She recalled her admittedly favorite patient who she now understands why she needed therapy, just living in this city would leave one with a few scars. Yet she still couldn't understand why despite living and working in Yokohama, Natsuko decided to go to therapy in Tokyo, a place almost an hour away even by train.
    There are still therapy offices and options in this town, so it's not like she needed to go to Tokyo to assess it. Perhaps it was simply cheaper? No, if she didn't seem like the type to be short of money. Coul-
"Hey Boss! Get me a cup of sake!" Yukina was interrupted from her thoughts by the voice of a woman taking a seat to her left. Looking up, she saw a young woman with a dark bob cut and a metallic yellow, almost gold, butterfly hair clip, she was slowly taking sips from her glass.
"You know, it isn't polite to stare." The woman's magenta eyes met Yukina's, a shade both dangerous and mesmerizing.
"Oh, sorry." The therapist apologized awkwardly, though she was sure she hadn't been looking at the woman even nearly long enough for it to count as staring.
"Different places have different definitions of what counts as staring." The woman chimed as if reading the other's thoughts before taking a long sip of sake. Yukina decided to call her Butterfly.
"You clearly have a different definition, so where are you from?" The woman asked after about a second of silence.
"...Tokyo..." Yukina replies hesitantly.
"Pretty far from here, no wonder you looked so alarmed. This city isn't exactly the best for outsiders." The woman commented through sips of sake. 
"So why'd you come here? Tourist?"
"Missed my stop on the way home from work."
"Ah, what's your job?" Butterfly asked.
"Therapist," Yukina answered, "what's yours?"
"Physician."
"A therapist and a physician walk into a bar. Sounds like the beginning of a bad joke." Yukina chuckled while taking a sip of amazake, the sweet alcohol sliding down her tongue.
"By the way, what should I call you, therapist-san?"
"Hirai. You?" Yukina said quickly.
"Yosano." She grinned faintly, then turned away and took a small sip of her drink.

[Yosano]

The head (and only) physician of the Armed Detective Agency decided after a long day of work to head to a nearby bar. The place was well-lit but quiet, in a rough part of town where the over and underworlds meet in a booze-filled sanctuary, welcoming sinners and monsters alike for the low price of a few bottles, cups, and shots. Perfect for the Angle of Death. Heading up to the bar counter, she sits down in her usual spot next to an alarmed-looking woman around her age sitting where her older brother would if they had gone drinking together, but hey, this was a public space with no assigned seats. Figuring this woman wasn't from around town, Yosano decided to strike up a conversation, learning of her occupation and business in Yokohama.
"A therapist and a physician walk into a bar. Sounds like the beginning of a bad joke." The two doctors laughed halfheartedly at the comment, with the therapist taking a sip of what looked like amazake.
"By the way, what should I call you, Therapist-san?"
"Hirai, and you?"
"Yosano." The Physician answered in a friendly tone, finding the woman next to her quite pleasant, for now. Their conversation carried on, along with the emptying and refilling of their cups; moving past that of small talk and more to a little game played back at the agency. She took a sip of her sake, the sounds of the outside world too quiet to note, but not not soft enough to forget.
"...and what about that man?" Yosano asked the therapist, pointing at a man who walked into the bar, ordered a bottle of rum, and proceeded to get hammered.
"hmm...he looks well off, by the way he walks he's someone with a position in power, maybe a boss...or police officer.. or heck, a father. He's too drunk to only be here to unwind so it's likely he's here due to something he feels the need to drink off." Hirai deduces correctly. Much to the physician's shock and delight. She couldn't help but feel comforted around the near stranger, perhaps because she reminded her of her brothers a lot.
"That's three in a row." Yosano complements after that deduction. "Ever considered being a detective?"
"...No that's... I've heard it's pretty dangerous. Plus I don't wanna be..." Hirai sighs, lowering her head onto the counter, perhaps either tired, drunk, or both. Yosano watched the other's long bangs fall over her closed eyes and almost gasped at the uncanny resemblance she had to her older brother and best friend.
"um... I thought it was impolite to stare." Yosano blinks at the emerald-colored eye, (now that she thinks about it, also almost identical to that of the agency's eldest and most genius detective) looking tiredly up at her.
"Oh, sorry." The physician apologizes awkwardly. "Um... it's pretty late and since you don't seem too familiar with this place, why don't I get you to the station? You know, in a way so you won't be mugged and/or kidnapped?" She said the last part jokingly, but anyone would know that those would be more than likely to happen, especially to someone who didn't know the place.
"Yeah...that...that seems like a good idea." Hirai stands up groggily and soon, the two doctors are out of the bar and down the street. A few shady figures lurked in the alleyway, spotting the two young women, almost giddy at their good luck, only to be glad at their good luck once more for not immediately jumping at the opportunity when they realized one of them was Doctor Yosano of the detective agency, famous for her skill in healing...and carrying around sharp objects that include but are not limited to: knives, scalpels, saws, and machetes. All perfect tools for stabbing would-be predators.
As the pair got onto a taxi, Yosano contemplated just taking her companion to the station and hoping she sobered up by then but realized that would be unwise, noting that the woman was already exhausted and almost asleep. Dozing on the train would only be an unfortunate annoyance in any other city but quite dangerous in this one. Instead, the physician took a sleeping Hirai to the ADA company dorms, deciding she'd explain in the morning, and help the doctor get back home.
