1. The Coffee
The first time Trinity Santos flirted with you, she did it over a burnt cup of hospital coffee.
You were standing in the break room at 6:43 in the morning, half-awake, one hand wrapped around a mug, the other scrolling through patient notes on your tablet. The ED was already loud beyond the door. Monitors beeping, residents calling for labs, nurses moving with the sort of speed that made the whole place feel like a hive someone had shaken.
Trinity came in still tying her hair back, black scrubs wrinkled in that very specific I slept for three hours and woke up angry about it kind of way.
She stopped when she saw you.
“Wow,” she said.
You looked up immediately. “What?”
“Nothing.”
Your brow furrowed. “Is there something on my face?”
Trinity’s mouth twitched. “No.”
You lifted a hand to your cheek anyway, because people always said “nothing” when there was, in fact, something. “Are you sure?”
“Yeah.” She moved past you toward the coffee machine. “You just look good in the morning.”
You blinked at her.
Then you looked down at yourself.
Your scrub top was slightly untucked. Your badge was twisted backward. Your hair had been put up in the dark and had mostly surrendered. There was a pen tucked behind your ear that you didn’t remember putting there.
“I look exhausted,” you said.
“Both can be true.”
You stared at her for another second, waiting for the joke to finish forming.
It didn’t.
So you nodded seriously.
“Thanks. You look tired too.”
Trinity paused with her hand on the coffee pot.
Slowly, she turned her head toward you.
You offered her a polite smile.
Her lips parted like she was going to say something, then closed again. She poured her coffee with the expression of someone deciding whether or not to walk into traffic.
“You’re killing me,” she muttered.
You looked back down at your tablet. “I can switch the coffee out if it tastes bad.”
Trinity stared at the back of your head for a full three seconds.
Then she laughed.
Not loudly. Not enough for anyone else to notice.
Just this small, helpless thing that made her shoulders dip.
“No,” she said. “Coffee’s fine.”
You hummed, already reading again.
Behind you, Trinity leaned against the counter, watching you like you were a puzzle box with no visible seams.
“You’re really something,” she said.
“Thanks,” you answered automatically. “You too.”
She smiled into her mug.
You still had no idea.
2. The Scrub Cap
The second time, it was during a psych consult.
You’d been called down for a patient who was refusing treatment, paranoid and overstimulated from the chaos of the ED. Trinity was the resident assigned to the case, standing outside the room with her arms crossed, explaining the situation fast enough that most people would’ve missed half of it.
You didn’t.
You listened, nodded, asked two questions, and then went in.
Twenty minutes later, the patient was calmer, sitting on the bed with a blanket around her shoulders and a cup of water in her hands. Trinity watched you through the glass with something unreadable on her face.
When you came back out, she stepped aside to let you through.
“That was impressive,” she said.
You tapped something into the chart. “She needed less stimulation, not six people talking over each other.”
“Yeah, but you got her to trust you in, like, two minutes.”
“She was scared.”
Trinity tilted her head. “You always do that.”
“Do what?”
“Make it sound simple.”
“It was simple.”
“No, it wasn’t.” Trinity moved closer, voice lowering. “You’re just good.”
You glanced up.
There it was again. That look. Warm. Sharp. Like she’d found something she wanted to touch but knew better than to reach for in the hallway.
Your brain politely sorted it into professional compliment and moved on.
“Thank you,” you said. “You handled the clinical side well.”
Trinity blinked.
Then her eyes narrowed slightly, amused and offended all at once.
“You’re complimenting me back?”
“Yes?”
“Like this is peer review?”
You frowned. “Was I not supposed to?”
She huffed a laugh and leaned one shoulder against the wall. “Okay. Let me make this easier.”
You looked at her fully now.
Trinity reached up and tugged at the edge of your scrub cap. It had slipped slightly, probably from you running your hand over your hair too many times.
“There,” she said, smoothing it into place. Her fingers lingered just long enough to be noticeable to anyone with a functioning sense of romance.
You did not have one of those.
You immediately touched the cap yourself.
“Oh. Was it crooked?”
Trinity’s hand dropped.
Her face went blank.
Then she looked away, biting the inside of her cheek.
“Yeah,” she said. “Terribly crooked. Medical emergency.”
“Why didn’t you just say that?”
“I did, in my own way.”
You nodded. “Thanks for fixing it.”
Trinity inhaled slowly through her nose.
“Anytime.”
And because you were you, you added, “It’s good to know you’re observant.”
Trinity stared at you.
Then she whispered, “Unbelievable.”
You smiled faintly, assuming she meant the patient case.
3. The Ambulance Bay
The third time was in the ambulance bay.
It was raining hard enough to turn the pavement silver. You’d gone outside for air after a difficult consult, the kind that left something heavy sitting behind your ribs. You weren’t crying. You weren’t even close.
You just needed the world to be quieter for two minutes.
Trinity found you anyway.
She always did that, somehow.
The door opened behind you and she stepped out, immediately making a face at the weather.
“Gross.”
“You can go back inside.”
“And leave you out here looking tragic and beautiful?” she asked. “No thanks.”
You glanced at her. “I don’t look tragic.”
“No. You do.”
You considered that.
“Is that a bad thing?”
Trinity looked at you like you’d just handed her a scalpel blade-first.
“No,” she said slowly. “That was not the part I expected you to question.”
You tucked your hands into your scrub pockets. “I’m fine.”
“I didn’t ask.”
“You were about to.”
She smiled then, soft and lopsided. “Maybe I just wanted to stand next to you.”
That should have done it.
That should have clicked.
The rain. The quiet. The way Trinity had stepped close enough that your shoulders nearly touched. The way her voice gentled only when she spoke to you.
Instead, you glanced toward the parking lot.
“Are you avoiding someone?”
Trinity’s smile fell open into disbelief.
You kept going, because unfortunately, once you found a possible explanation, your brain liked to trot after it like a little hound.
“Because if you are, I can stand here longer. Make it seem like we’re discussing a patient.”
Trinity pressed her lips together.
Her eyes dropped to the ground.
For one strange second, you thought she might be upset.
Then she laughed so hard she had to cover her mouth.
You stared.
“What?”
She shook her head, rain catching in the loose pieces of hair near her face.
“Nothing. Nothing. You’re just…” She looked at you again, eyes bright. “You’re impossible.”
“I’m trying to be helpful.”
“That’s the problem.”
“I don’t understand.”
“I know.”
You frowned harder.
Trinity softened.
She reached out, carefully brushing a raindrop from the shoulder of your scrub top.
“Come back inside before you freeze.”
“I’m not cold.”
“You’re shivering.”
You looked down at your own arm.
You were, actually.
“Oh.”
Trinity’s smile returned, smaller this time.
“Yeah. Oh.”
She opened the door and held it for you.
You walked in first.
Behind you, Trinity murmured, “One day, I’m going to flirt with you so directly you’ll have no choice.”
You half-turned. “Did you say something?”
“Nope.”
4. The Dinner Invite
The fourth time, she brought food.
That was serious.
You were in your office with the lights dimmed, your shoes kicked off beneath the desk, and a stack of notes glaring at you from the screen. It was past the end of your shift. Technically, you could leave.
Realistically, the charting goblin had its claws in your ankle.
A knock sounded at the doorframe.
You looked up.
Trinity stood there holding two takeout bags.
“Are you busy?”
“Yes.”
She lifted the bags.
You paused.
“Less busy than I was.”
She grinned and came in like she’d won something.
You moved a pile of papers so she could put the food down. The smell hit first. Warm rice, grilled meat, garlic, something spicy enough to make your stomach wake up and file a formal request.
“You didn’t have to get me dinner,” you said.
“I know.”
You looked into one of the bags. “Did someone order too much?”
“No.”
“Did the restaurant mess up?”
“No.”
“Did a patient’s family bring this?”
Trinity stared at you.
“I bought you dinner.”
You looked up.
“Why?”
The question came out genuinely.
Trinity’s expression did something complicated. Amusement first. Then fondness. Then a little flicker of exasperation.
“Because I like feeding you.”
You absorbed that.
Slowly.
Carefully.
Still incorrectly.
“That’s very kind.”
Her eyes narrowed. “Kind.”
“Yes.”
“I brought you your favorite.”
“You know my favorite?”
“You get the same thing every time we order from there.”
“That’s pattern recognition.”
“That’s interest.”
You nodded. “Both can be true.”
Trinity dropped into the chair across from your desk and rubbed a hand over her face.
“I swear to God.”
“What?”
She looked at you through her fingers. “Do you think I bring dinner to everyone?”
You thought about it.
“You’re friends with Dennis.”
“That’s not what I asked.”
“And Mel.”
She lowered her hand. “You are dodging the point so hard it’s becoming athletic.”
“I’m not dodging. I’m answering.”
“You’re not answering the right question.”
“What’s the right question?”
Trinity leaned forward, elbows on her knees.
Her voice softened.
“Why do you think I know your favorite order?”
You opened your mouth.
Closed it.
The answer that came first was practical. Because you worked together. Because she noticed things. Because doctors noticed patterns. Because residents learned people’s habits when they were sleep-deprived and trapped in the same building for too many hours.
But Trinity wasn’t looking at you like this was about sesame chicken.
She was looking at you like she had been standing at a door for weeks, knocking with flowers, fireworks, a brass band, and a handwritten sign, and you had kept asking if the noise was maintenance.
Your face warmed.
“I don’t know,” you said quietly.
Trinity’s gaze flicked across your face.
For once, she didn’t make a joke.
“Think about it,” she said.
Then she pushed one container toward you and picked up her chopsticks like she hadn’t just rewired half the room.
You did think about it.
For the entire meal.
For the rest of your charting.
For the drive home.
For two days after.
+1. The Time You Did
The time you finally noticed, Trinity wasn’t even trying.
That was the ridiculous part.
It was late again. Of course it was. The ED had been brutal all day, one long unraveling thread of chest pain, psych holds, trauma alerts, and family members crying into vending machine coffee.
You found Trinity sitting alone in the nearly empty break room, head tipped back against the cabinet, eyes closed.
For once, she looked truly tired.
Not cute-tired. Not Trinity-tired, with sarcasm sharpened and ready.
Just tired.
You stepped inside quietly.
“Hey.”
Her eyes opened.
The second she saw you, her face changed.
Not dramatically. Not enough for anyone else to catch.
But you did.
Her shoulders eased. Her mouth softened. Something guarded in her expression loosened, like her body had recognized you before she decided whether to allow it.
“Oh,” she said, voice rough. “Hey.”
Your stomach flipped.
Small.
Dangerous.
Warm.
You stood there with one hand still on the door.
And suddenly, all of it came back.
You look good in the morning.
You’re just good.
Maybe I just wanted to stand next to you.
I like feeding you.
Think about it.
You had thought about it.
Apparently your brain had needed to receive the evidence, organize it, mislabel it, archive it, retrieve it, then finally set it on fire.
Trinity rubbed at one eye. “You okay?”
You walked farther into the room.
“I think you’ve been flirting with me.”
Trinity went very still.
Then she sat up.
Slowly.
“Sorry?”
“You’ve been flirting with me,” you said again, more certain this time.
Her expression cracked.
A smile crept in at one corner of her mouth.
“Have I?”
You gave her a look. “Don’t do that.”
“Do what?”
“Pretend you haven’t.”
Trinity leaned back in her chair, now far too pleased for someone who had been half-dead thirty seconds ago.
“I don’t know. This is a pretty serious accusation.”
“You told me I looked good in the morning.”
“You did.”
“I looked like I’d been dragged through a supply closet.”
“Still worked for me.”
Your face heated.
Trinity noticed.
Of course she noticed.
Her smile softened into something less smug and more careful.
“You finally caught up,” she said.
“I’m sorry it took me so long.”
“Don’t be.” She shrugged, but the movement wasn’t casual enough to fool you. “It was kind of cute.”
“I thought you were just being nice.”
“I am nice.”
You stared at her.
She sighed. “Fine. Nice adjacent.”
You laughed before you could stop yourself.
Trinity’s face changed again.
That was when you really knew.
Not because she flirted. Not because she teased. Not because she brought you dinner or stood too close in the rain or looked at you like you were the only steady thing in a collapsing hospital.
Because when you laughed, Trinity looked relieved.
Like she’d been waiting to hear that sound all day.
Maybe longer.
You stepped closer.
Her eyes followed you.
“Are you flirting with me right now?” you asked.
“No,” she said.
You raised an eyebrow.
Trinity smiled.
“Now I’m waiting.”
“For what?”
“For you to decide what you want to do about it.”
The room went quiet.
Beyond the door, the ED kept roaring. Phones ringing. Wheels squeaking. Someone calling for an attending. Life continuing in all its fluorescent chaos.
But inside the break room, everything narrowed down to Trinity Santos sitting in front of you, watching you with that impossible mix of patience and nerve.
You took another step.
Then another.
Her smile faded, but only because her lips parted slightly.
You stopped in front of her.
“I want you to flirt with me again,” you said.
Trinity’s eyes darkened with amusement.
“Yeah?”
You nodded.
“But more directly this time.”
She tilted her head back to look up at you.
“Okay,” she said softly. “I want to kiss you.”
Your breath caught.
There it was.
No room for misinterpretation.
No clinical loophole.
No colleague-shaped excuse to hide behind.
Just Trinity.
Just wanting.
Just you, finally understanding.
You swallowed.
“I noticed that one.”
Her smile returned.
“Good.”
Then she stood, slow enough for you to move away if you wanted.
You didn’t.
Her hand touched your waist first, careful and warm through the fabric of your scrubs. Your fingers curled lightly into the front of her scrub top, exactly where you’d wanted them for longer than you had allowed yourself to admit.
Trinity leaned in.
Paused.
Still giving you a way out.
You closed the distance yourself.
The kiss was soft at first. Almost questioning. Then Trinity made this small sound against your mouth, half relief and half finally, and you forgot every clever thing you had ever almost said.
When you pulled back, she stayed close, forehead nearly touching yours.
“You know,” she murmured, “for a psychiatrist, you are impressively bad at reading romantic cues.”
You breathed out a laugh. “In my defense, you’re very sarcastic and I’m very autistic.”
Trinity paused.
Then her expression softened so quickly it almost stole the air from the room.
“Okay,” she said, thumb brushing once over your waist. “Fair defense.”
“In my other defense, you’re very pretty and that makes your sarcasm harder to decode.”
Her grin came back slowly.
“There it is.”
“What?”
“You flirting back.”
Your face warmed. “Was that flirting?”
“Baby,” Trinity said, delighted now, “that was practically a love letter.”
You rolled your eyes, but you were smiling.
“In my defense,” she added, “I bought you dinner.”
“I understand that now.”
“Do you?”
“Yes.”
“Because I can do it again. For clarity.”
You smiled.
Trinity’s thumb swept once over your waist.
This time, you noticed.
This time, you leaned closer.
“Dinner sounds good,” you said. “But I think I need more evidence.”
Trinity’s grin turned slow.
Dangerous.
Delighted.
“Oh, I can provide evidence.”
And when she kissed you again, there was nothing subtle about it.
