Mia sat on the floor beside her bed for a solid four minutes after the drilling upstairs turned into the unmistakable, increasingly frantic sound of a man calling a cat's name up and down a hallway, and she did not move to help him even once.

"Barnaby," Lucas's voice said, muffled through the wall, clipped and controlled in the way of someone determined not to sound as panicked as he clearly felt. A pause. Footsteps. "Barnaby."

There was something deeply, shamefully satisfying about listening to Doctor Six A.M. Drill Sergeant lose his composure over a cat, especially when the cat in question was currently doing his best loaf impression directly on top of Mia's favorite pillow, snoring with the confidence of an animal who had never once considered the possibility of consequences.

"You're famous," she told him. "He's saying your name like it's a magic word."

The cat did not open his eyes.

It took another two and a half minutes -- she counted, mostly because counting felt like a productive use of the time she was spending doing absolutely nothing to help -- before there was a knock on her door. Not a polite knock. A structured one, three even raps, the kind of knock that suggested the person on the other side had already calculated the optimal force and frequency for getting a response.

Mia got up, brushed cat hair off her leggings with theatrical slowness, and opened the door to find Lucas standing there in the same gray t-shirt from earlier, now slightly damp at the collar, his composure fraying visibly at the edges. There was a faint sheen of stress-sweat on his forehead that had nothing to do with the gym equipment he'd been installing an hour ago.

"Have you seen a cat," he said. Not a question, exactly. More of a demand phrased with just enough grammar to pass as polite. "Gray. Large. British Shorthair. He gets out sometimes when the balcony door isn't fully latched, and I need to find him before he--"

"Before he what," Mia said, leaning against the doorframe with the particular smugness of a woman holding all the leverage in a negotiation the other party didn't know was happening yet. "Before he judges your decor?"

Something in Lucas's face shifted -- relief, maybe, or the specific irritation of a man who has just realized the person in front of him knows exactly where his cat is and is choosing, deliberately, to enjoy the moment. "He's in your apartment."

"That's a very confident assumption."

"You're standing there covered in gray fur."

Mia looked down. He was right, infuriatingly. A fine dusting of silver hair clung to the front of her cardigan like she'd been rolling in it, which, she supposed, she basically had. "Okay, fine. He's in here. He came in through my window like he owned the place, and honestly, at this point, I think he might."

"Can I--" Lucas started forward, and Mia, without entirely meaning to, shifted her weight to block the doorway just slightly, not enough to be an actual obstacle, just enough to make a point.

"He's sleeping."

"I need to bring him home."

"He's sleeping on my pillow. Specifically. With his whole body weight. He looks extremely comfortable and extremely unwilling to relocate."

Lucas exhaled through his nose in a way that suggested he was recalculating his approach in real time, treating this the way he probably treated a nervous dog in an exam room -- assess, adjust, proceed carefully. "Mia." Her name in his mouth landed strangely, more familiar than it had any right to feel after one disastrous encounter and one bag of accidental cat hair. "I appreciate that he's comfortable. But he's not supposed to leave the apartment unsupervised, and I'd like him back."

"You say that like he's a library book."

"He's a twelve-pound animal with a preexisting heart murmur that I monitor closely, and he shouldn't be jumping across a six-inch gap between balconies four stories up." The clinical flatness of his voice cracked, just slightly, on heart murmur, and for the first time since she'd met him, Mia caught a flicker of something underneath the controlled surface -- actual worry, not performance.

"Look," Mia said, before stepping aside. "I'm not trying to be difficult. I just watched him fall asleep like it was the safest place in the world, and I don't especially want to be the one who wakes him up to hand him back to a man who was drilling through my wall three hours ago."

"I understand the position," Lucas said, with the careful, measured patience of someone talking a nervous client through a decision they'd already made in their head. "But he has a preexisting cardiac condition that requires monitoring, and an unfamiliar environment isn't ideal for that."

"He seems pretty familiar with my pillow already."

"That's exactly my point."

Mia considered this, considered him, considered the particular flavor of stubbornness radiating off a man who had clearly not expected his morning to include negotiating with a stranger over the location of his own pet. "Fine," she said finally. "But you're getting him yourself. I'm not the delivery service."

She stepped back and let him in.

The apartment looked, she realized belatedly, deeply unflattering under scrutiny -- scattered fox studies still on the floor from Barnaby's earlier arrival, a mug of cold coffee, three days of dishes stacked with the confidence of someone who believed in "getting to it eventually." Lucas's eyes swept the room once, fast, with the barely restrained twitch of a man cataloging every code violation he was too polite to mention out loud, before landing on the bed, where Barnaby lay sprawled in the exact center of the pillow like a small furred emperor holding court.

"There he is," Lucas said, and something in his voice softened in a way that had nothing to do with Mia at all. He crossed the room and crouched by the bed. "Hey, buddy."

Barnaby opened one eye, regarded his owner with the specific disdain of royalty being disturbed mid-nap, and did not move.

"Come on," Lucas said, reaching for him.

Barnaby made a sound Mia had never heard a cat make before -- a low, indignant, almost human groan of protest -- and burrowed deeper into the pillow, one paw extending to hook possessively into the fabric of Mia's comforter.

"He doesn't want to go," Mia said, unable to keep the delight out of her voice.

"He's a cat. He doesn't have opinions about interior design."

"Clearly he does. Clearly he prefers my interior design."

Lucas tried again, sliding both hands underneath Barnaby's substantial midsection, and lifted -- or attempted to. The cat became, in that instant, remarkably and specifically boneless, an amorphous twenty-pound sack of gray fur that refused to hold any shape that could be carried with dignity. Lucas adjusted his grip. Barnaby oozed sideways. Lucas adjusted again. Barnaby made a sound like a dying accordion and flattened himself even further into the pillow, claws hooking gently but firmly into the comforter.

"He's doing this on purpose," Lucas said, with the wounded disbelief of a man who had never once in his professional life been out-strategized by a house pet.

"I think that's exactly what he's doing, yes."

"He likes structure. He likes routine. This is completely uncharacteristic."

"Maybe he likes my routine better." Mia crossed her arms, watching Lucas kneel on her bed in his gym shorts, wrestling gently with a cat who had apparently unionized against him. It was, objectively, one of the funniest things she had witnessed in recent memory, and she was doing absolutely nothing to hide how much she was enjoying it. "Try the toy. The laser thing. Don't vets always have a laser thing?"

"I don't carry a cat toy with me at all times, no."

"Rookie mistake."

Lucas shot her a look that suggested he did not appreciate being coached through cat retrieval by a woman in a WITCH PLEASE t-shirt, but he tried a different tactic anyway -- lower, gentler, both hands cupping Barnaby's front paws instead of his midsection, murmuring something too low for Mia to catch. For one brief, almost tender moment, it looked like it might work. Barnaby's ear flicked. His body loosened fractionally.

Then Mia, without thinking, reached over and scratched the exact spot behind Barnaby's ear that she'd found earlier, the one that had made him lean helplessly into her hand -- and the cat immediately abandoned all cooperation, twisting free of Lucas's grip entirely and resettling himself, smug and unbothered, directly in Mia's lap instead.

There was a beat of silence.

"You did that on purpose," Lucas said.

"I really didn't." Mia held up both hands, though the laugh she was fighting back undercut the innocence considerably. "He just likes me. It's not my fault I'm likable."

"He's supposed to be food-motivated and routine-driven. He's not supposed to have preferences."

"Have you met a cat before? They're famous for having preferences. It's basically their whole personality."

Lucas sat back on his heels, visibly recalibrating, the particular expression of a scientist encountering a data point that refused to fit the model. He looked, for just a second, less like a man in complete command of his surroundings and more like someone genuinely at a loss -- and something about that, the crack in the competence, made Mia's chest do an unwelcome, complicated thing she didn't have time to examine.

He tried once more, this time attempting the specific low, clicking noise Mia assumed was meant to be soothing, judging by the way his voice dropped half an octave and lost, briefly, its usual clipped precision. Barnaby's ear twitched toward the sound with mild interest, weighed the offer, and rejected it, resettling himself with the deliberate finality of a landlord declining a lowball bid.

"That was almost cute," Mia said. "The voice. Very unexpected from you."

"It's a standard technique for calming anxious animals."

"Sure. A standard technique. Nothing personal about it at all."

"Correct." But his ears had gone faintly pink at the tips, and Mia decided, privately, that this small, involuntary reveal was worth filing away for later, alongside the accordion-groan and the flashlight incident, in the growing catalogue of things about Lucas Vance that did not match her first, furious impression of him.

"Okay," he said finally. "New approach."

"Which is?"

"He stays. Temporarily." He said the word like it cost him something, like temporarily was a language he wasn't fluent in. "Until he calms down enough to be moved without an incident. I'll come back this evening."

"You're just going to leave your cat with the woman whose walls you drilled through at six a.m.?"

"You seem competent enough to keep a cat alive for six hours."

"That's the nicest thing you've said to me all day."

"The bar was extremely low."

Despite herself, Mia laughed -- a real one, short and surprised out of her -- and something shifted almost imperceptibly in the room, the temperature of the whole encounter tipping from adversarial into something looser, more like banter than combat. Lucas stood, brushing cat hair off his knees with the same brisk efficiency he probably applied to everything, and paused at the door.

"Feed him the food in the labeled container by six," he said. "Not human food. Nothing off your plate, regardless of how he asks."

"He's very persuasive."

"I'm aware. I live with him." A beat. "I'll text you my number. For the handoff."

"For the handoff," Mia repeated, deadpan. "Very romantic."

Lucas's expression did something complicated -- not quite a smile, but close enough to make Mia regret the joke slightly, mostly because she couldn't tell if he'd taken it as a joke at all. "Six o'clock," he said, and left, the door clicking shut with the same precise, unhurried finality as everything else about him.

Mia looked down at Barnaby, who had already resettled himself in her lap with the boneless satisfaction of a cat who had won something significant, though the exact nature of the victory remained unclear even to Mia.

"Well," she told him. "This is a whole thing now, isn't it."

Barnaby began, with great ceremony, to groom one enormous paw, entirely unbothered by the six hours of unsupervised custody he'd just arranged for himself.

By four o'clock, Mia had abandoned any pretense of working on the fox illustration and had instead spent an embarrassing amount of time researching British Shorthair care online, just in case, because the last thing she needed was to be responsible for something happening to Lucas Vance's cat with the heart murmur while he was at work saving other people's pets. She learned that British Shorthairs were prone to obesity, which, glancing at Barnaby currently sprawled across her entire windowsill like a furred draft excluder, tracked. She learned they were known for being calm and easygoing, which did not track at all, given the accordion-groan incident from that morning. She learned they typically bonded strongly with one person.

She looked at Barnaby. Barnaby looked back at her with the flat, unblinking confidence of an animal who had already decided who that one person was going to be, regardless of what the internet said about typical bonding patterns.

She texted Priya an update around two, mostly out of boredom, partly because narrating the day out loud to someone else felt like the only way to make sense of how strange it had turned.

MIA: update: I am now the proud temporary guardian of my hot, insufferable neighbor's cat

PRIYA: "temporary"

MIA: SIX HOURS, priya. six hours and then he comes back for him

PRIYA: and you're doing what with those six hours

MIA: googling cat facts. what else would I be doing

PRIYA: I can think of several other activities but go off

MIA: absolutely not what this is

PRIYA: you brought up his forearms unprompted yesterday. i'm just saying the data trend is not neutral

Mia had, in fact, not brought up his forearms unprompted -- Priya had asked, very specifically, whether the neighbor was "built like someone who owned a stopwatch," and Mia had answered honestly, which did not, in her opinion, count as unprompted commentary. She closed the chat before Priya could point out that this distinction was, itself, extremely telling, and went back to reading about the specific dietary needs of an overweight British Shorthair, mostly to avoid thinking about anything else.

At five-forty, her phone buzzed with a text from an unknown number.

LUCAS: This is Lucas. Confirming 6pm for pickup. I'll knock.

MIA: very formal. do you also send confirmation texts before dates

LUCAS: I don't see the relevance of that question to cat logistics.

MIA: no relevance at all. purely curious about your texting habits, doctor.

There was a pause long enough that Mia assumed the conversation was over, and then:

LUCAS: I do not currently have occasion to text confirmations before dates.

MIA: currently

LUCAS: I have a patient in five minutes. I'll see you at six.

Mia stared at the screen for slightly longer than the message warranted, turning currently over in her head like a stone she couldn't quite skip properly across water, before setting the phone face-down and telling herself, with the particular firmness of someone who did not believe themselves, that it meant absolutely nothing at all.

At six o'clock exactly -- because of course it was exactly six, not 6:01, not 5:58 -- there was a knock at her door. Three even raps.

Mia opened it to find Lucas still in his clinic scrubs, a faint smear of what she chose not to investigate too closely on one sleeve, looking, for the first time since she'd met him twelve hours earlier, genuinely tired rather than simply composed.

"Long day?" she asked, before she could stop herself.

"A dog came in with a swallowed sock. It resolved fine." He said it the way he probably said everything at work -- flat, efficient, a fact delivered and filed. "I appreciate you keeping him."

"He was good company. Mostly he slept."

"That tracks. He sleeps sixteen hours a day on average."

"Sounds nice, honestly."

Something flickered across Lucas's face -- not quite a smile, but the shadow of one, tired and unguarded in a way his usual careful expression rarely allowed. "Some days I envy him."

Barnaby, curled once again in the center of her pillow, did not so much as lift his head at the sound of his own owner's voice, and Mia found herself watching Lucas watch his cat with an expression she hadn't expected from him -- not frustration, exactly, but something softer, more resigned, the look of a man who loved something stubborn and difficult and had long since stopped expecting it to make his life easier.

"Give me a second," she said, and crossed the room to gather Barnaby up, warm and heavy and smelling faintly of her own detergent now, which felt, obscurely, like a small victory she hadn't been trying to win. He came without protest this time, draping himself over her arms with the boneless trust of an animal fully secure in his own welcome, and something in her chest tightened, unexpectedly, at the thought of handing him back.

"Thank you," Lucas said again, taking the cat from her with careful, practiced hands, the transition smooth despite everything that had gone wrong that morning. "Truly. I know this wasn't the introduction you'd have chosen for a new neighbor."

"No," Mia agreed. "I'd have gone with literally anything else. A fruit basket, maybe. A normal knock at a normal hour."

"I'll aim for that next time."

"There's going to be a next time?"

Lucas paused in her doorway, Barnaby settling against his shoulder with a contented rumble, and looked at her for a beat longer than the question strictly required. "He likes it here," he said finally, like it was a fact he was still adjusting to, filed under a category his usual systems hadn't accounted for. "I have a feeling there will be."

He left before she could formulate a response to that, and Mia stood in her doorway long after his footsteps had faded down the hall, feeling, against every instinct honed by a lifetime of avoiding exactly this kind of complication, unreasonably pleased by the prospect of a next time.
