Chapter 1: Dante

Chapter Text

After midnight, Hell’s Kitchen stops pretending to be respectable.

Steam rises from the pavement in slow white breaths. Taxis drag neon across wet asphalt. Laughter escapes open doorways with the brittle edge of people delaying whatever waits for them at home. The city does not sleep so much as pace.

The Black Thorn welcomes anyone with cash and the good sense not to ask unnecessary questions, but certain types always find their way there. Detectives between cases. Informants nursing whiskey they cannot afford. Lawyers pretending they are off the clock. People buying information, and people selling it. Discretion comes included with the bill.

Detective Erwin Smith sits alone at the bar in a white shirt with the sleeves rolled up at the forearms, his tie loosened just enough to suggest the day has ended without implying relaxation. His jacket hangs over the back of his chair. His thumb traces the rim of his bourbon glass without lifting it.

Off duty is supposed to mean distance. Fewer voices. Less paperwork. A temporary ceasefire between a detective and the endless procession of other people’s bad decisions. For Erwin, it usually means taking the same thoughts somewhere quieter and examining them until sleep becomes theoretical.

Tonight, he has rules.

Sit still.

Drink something that does not taste like punishment.

Leave before solitude starts feeling theatrical and he becomes the kind of man who talks to strangers just to prove the world still answers back.

He has seen that version of himself before. He does not especially like him.

The Black Thorn suits him because it asks very little. Nobody pays attention unless they have a reason. Conversations happen in measured tones, private enough to suggest discretion but never quiet enough to feel intimate. It is the kind of place where silence passes for company.

The door opens somewhere behind him, letting in a brief draft of wet city air.

Erwin notices the newcomer before he has any sensible reason to. It is not because the man is loud. He is not. He enters without performance, without hesitation, without that common drunken uncertainty most people have when stepping into a crowded room after midnight. He simply appears in the doorway, pauses long enough to read the space, and then moves.

He’s shorter than most of the men inside, though that is the least useful thing to notice about him. Compact. Controlled. Dark hair damp from the rain, pushed back carelessly from a sharp, unsmiling face. A black shirt fits cleanly across narrow shoulders, sleeves rolled just enough to expose lean forearms that look built for function rather than display.

Dangerous, Erwin thinks.

Then, with immediate irritation: attractive.

He lifts his bourbon and takes a drink. The alcohol sits warm on his tongue, bitter enough to punish him for looking too long. He turns back toward the bar, studies the bottles lined against the mirror, and gives himself three seconds to behave like a reasonable adult.

On the fourth sip, he looks again.

The stranger cuts through the room with quiet efficiency. He doesn’t brush against anyone. Nor does he apologize or glance around in search of approval or company. People shift without seeming to understand why, making just enough space for him to pass. It is subtle, almost nothing, but Erwin has spent too many years watching rooms change shape around violence not to notice.

The man takes the empty stool two seats down and orders whiskey in a voice almost too low for Erwin to catch.

The bartender pours without asking for clarification.

Regular, then.

Or memorable.

“You’re being a creep, Detective Smith” the bartender says, polishing a glass with a smug smile on his face.

Erwin glares at him.

“I’m just observing, Marco.”

“Same thing, after midnight.”

“You know what I do for a living.”

“I do. Which kinda makes it worse.”

Erwin exhales through his nose, but the corner of his mouth threatens to move. He refuses to let it. The bartender, who has survived enough detectives to recognize silence as defeat, slides Erwin’s glass half an inch closer and says nothing else.

The stranger glances sideways.

Gray eyes.

Cool. Flat. Assessing.

Not curious, exactly. Not friendly. More like Erwin has been entered into a ledger and found inconvenient.

Erwin meets his gaze before caution has time to interfere.

For one strange second, The Black Thorn recedes around them. The music, the low conversations, the clink of glass against wood. All of it drops back, blurred at the edges, leaving only that narrow line of attention between two men who have no reason to notice each other and are doing it anyway.

Then the stranger looks away.

That should be the end of it.

It is not.

Erwin’s second bourbon arrives. Condensation gathers slowly around the base of the glass. He tells himself he is thinking about work, about the cold case waiting on his desk, about the witness who changed her statement three times and cried during the fourth. All of those things are real.

None of them explain why he is aware of the stranger’s hand around his whiskey glass.

Long slender fingers. Steady grip. No ring.

Erwin hates himself a little.

Somewhere between the second bourbon and the third he absolutely should not have ordered, the empty chair beside him scrapes against the floor.

The stranger sits down without asking.

Up close, he is worse.

Sharper than he had looked from a distance. Better-looking in a way that feels less like beauty and more like a warning. His mouth is set in a line that suggests irritation is his resting state. There is a faint scar near one knuckle.

“You look like you’re waiting for bad news,” the stranger says.

His voice is low, dry, almost bored.

Erwin turns his glass slowly between his fingers. “Usually saves time.”

“Does it?”

“Bad news has a way of finding me.”

The man’s eyebrow lifts a fraction, “Maybe I’m not bad news.” He takes a sip of his whiskey.

Erwin looks at him properly. “No,” he says, “I don’t think that’s true.”

A faint pause follows. Not awkward. Measured. The stranger studies him with the dispassionate focus of someone deciding whether a locked door is worth opening or breaking.

Erwin knows he should let the silence win. Instead, he says, “You have a name?”

The man takes another sip of whiskey before answering, “Dante.”

A name pulled from an inside pocket before the question has fully landed.

Fake, Erwin thinks immediately.

He cannot prove it. There is no tell obvious enough to name. No visible flinch, no hesitation, no nervous shift of the eyes. If anything, the lie is elegant because it has no rough edges. It just does not fit him.

“Erwin,” he says.

The stranger’s gaze flicks over him once, quick and surgical.

“Detective Erwin. Off duty.”

“Is that supposed to make it less sad?”

Erwin laughs before he can stop himself, which surprises him.

It seems to surprise Dante too, though only faintly. His mouth shifts, not quite a smile, and then settles back into its usual line of controlled displeasure. Somehow that almost-smile is worse than an actual one would have been.

After that, the night begins to lose its clean edges.

Not quickly. Not dramatically. Just by degrees.

Whiskey lowers the volume on caution. The bar fills and thins around them. Led Zeppelin playing from the speakers. Rain taps against the front windows in soft, persistent bursts. The bartender keeps pretending not to listen and fails with professional grace.

Dante gives almost nothing away.

He answers questions with half answers, insults with precision, and anything personal with a look flat enough to kill the subject where it stands. He claims to work in import logistics, which is such an obvious lie that Erwin nearly respects it.

“Import logistics,” Erwin repeats.

“Yeah..”

“Is that what we’re calling crime now?”

Dante does smile then.

Barely.

“If you have to ask, you’re bad at your job.”

Erwin should object. Instead, he drinks.

The conversation moves like a card game neither of them has agreed to play honestly. Erwin learns that Dante dislikes loud people, cheap cologne, and being away from home after midnight, though he seems willing to tolerate all three when the whiskey is tolerable. Dante learns that Erwin works too much, sleeps too little, and has the kind of relationship that needs therapy.

None of it is enough and at the same time–all of it, is too much.

Dante stays.

That becomes the real problem.

He stays through one drink, then another. He shifts closer without making a show of it, the movement so gradual Erwin only notices when conversation no longer requires either of them to raise their voices. The space between their shoulders narrows. Their knees nearly touch beneath the bar. Once, Dante leans in to say something cutting over the music, and Erwin catches the clean, expensive edge of his cologne beneath the whiskey and smell of rain.

The scent settles somewhere dangerous in his memory.

At some point, Dante’s hand rests on Erwin’s thigh.

Not by accident.

A warm, deliberate weight through the fabric of Erwin’s trousers.

Erwin looks down at it.

Dante does not.

The bastard keeps drinking as if nothing has happened, as if he has not just turned every nerve in Erwin’s body traitor.

Erwin could move.

He does not.

By 1 am, the rules Erwin made for himself have become legal fiction.

Sit still.

Drink something that does not taste like punishment.

Leave before loneliness starts making decisions.

It’s too late.

Dante is all dry contempt and controlled angles, every dismissive glance somehow sharpening Erwin’s interest instead of dulling it. He is not charming in any conventional sense. He is rude, evasive, and probably lying about everything that matters.

Erwin knows this.

It does not help.

“You’re doing it again,” Dante says.

Erwin drags his attention back to his eyes.

“Doing what?”

“Looking at my mouth.”

There is no embarrassment in the accusation. No flirtation softening it. Just blunt observation, which somehow makes it worse.

Erwin holds his gaze.

“I was thinking.”

“Dangerous hobby.”

“For both of us, apparently.”

Dante’s expression shifts.

Not much but enough.

Something darkens behind his eyes, quick and precise, like a match struck in a closed room.

The silence that follows is not empty. It presses in around them, warm with bourbon and rain and the mutual awareness of a line neither man has crossed yet.

Then Dante finishes his whiskey in one go and stands.

He is still steady on his feet. 

Annoying.

“Bathroom,” he says.

Erwin looks up at him.

It takes one beat too long for the word to become more than information.

Then Dante glances back.

His expression is cool, almost bored, but his eyes are not.

“Coming, detective?”

Erwin knows the correct answer.

He knows it with the full miserable clarity of a man who has spent his career watching people mistake impulse for fate.

He leaves cash on the bar anyway.

Dante’s mouth curves, small and satisfied, before he turns and walks towards the mensroom. Erwin follows a few seconds later.

The hallway to the mensroom is narrow and dim, lit by a flickering wall sconce that makes everything look vaguely criminal. The air smells like bleach, old plumbing, and stale beer.

Erwin follows close enough to catch the heat rolling off Dante’s frame.

At the restroom door, Dante pauses, one hand on the handle, turning just enough that Erwin can see the precise shape of his mouth in shadow.

“Tell me,” he murmurs, voice low and edged with amusement, “are all cops this bad at making responsible choices?”

Erwin steps closer until there’s barely space left between them. Dante smells too good. Like comfort, Erwin thinks and he’s so drunk he realises. 

“Only the experienced ones.”

Dante smiles at that.

It is not a pleasant smile. It is small, controlled, and edged with something that makes Erwin think of alleyways after rain and knives kept clean for a reason.

Then Dante’s hand closes around the front of Erwin’s shirt.

Erwin has time to register the pull, the sharp pressure at his collar, the narrow restroom door swinging open behind them. Then he is being dragged into the nearest stall, the lock snapping into place with a cheap metallic click that sounds much too final.

Dante closes the remaining distance like he has no patience left for implication.

The kiss is hard enough to bruise.

It is not tentative. It does not ask. It arrives like a decision already made, whiskey-warm and unforgiving, all teeth and pressure and the brief sting of Dante catching Erwin’s lower lip before forcing the kiss deeper.

Erwin answers before any thought can interfere.

One of his hands hits the stall door hard enough to rattle it in its frame. The other finds Dante’s waist and pulls him closer, because if this is a mistake, then apparently Erwin means to make it properly.

The bathroom stinks.

Erwin barely notices.

There is only Dante. The heat of him. The taste of whiskey on his tongue. The sharp, controlled way he takes up space even here, even drunk, even with Erwin crowding him against a stall wall.

Their mouths turn hungry.

Not romantic.

Not careful.

The kiss becomes a rough negotiation neither of them intends to lose.

Dante makes a low sound when Erwin changes the angle, impatient and pleased in the same breath. Erwin feels it against his mouth more than he hears it. Dante’s hands move with quick, certain purpose, gripping Erwin’s shirt, sliding over his chest, catching his jaw to hold him exactly where he wants him.

Control.

That is what Erwin notices through the bourbon and heat.

Dante does not kiss like a man carried away. He kisses like a man directing violence into something almost intimate.

It should make Erwin step back. It doesn’t. Instead, he tightens his grip and kisses Dante harder.

“You,” Erwin mutters against his mouth, half breathless, “are definitely not in import logistics.”

Dante’s mouth curves against his.

“Shocking.”

Then he bites Erwin’s lip teasingly, hungrily.

He shoves Dante lightly back against the stall wall just to feel the impact, just to watch the flash in those gray eyes sharpen.

“Problem?” Erwin asks.

Dante looks up at him with that same cool expression made unstable by drink and heat.

“Big one,” he says, a little out of breath, “You still talk too much.”

Then Dante’s hands move lower, deliberate and slow enough to feel intentional.

The pace changes.

Not cooler.

If anything, worse.

More dangerous for the restraint it implies.

Erwin watches the shift happen in real time. That razor-edged confidence narrowing into something hungrier, more focused. Dante breaks the kiss only long enough to drag his mouth along Erwin’s jaw, his throat, a line of heat and pressure that makes Erwin’s fingers tighten against the stall wall.

“Jesus,” Erwin breathes.

“Wrong name.”

The sarcasm should not be attractive. But it absolutely is.

Then he meets Erwin’s gaze.

Steady and knowing.

And with no rush at all, he begins to lower himself, one hand still curled in Erwin’s shirt as though keeping him exactly where he wants him.

Erwin stares down at him, pulse pounding hard enough to feel in his teeth.

“Dante—”

“Relax, detective.”

The command comes soft.

Far too effective.

Dante settles onto his knees like it’s a tactical decision rather than surrender, looking entirely too composed for a man half-drunk in a filthy Hell’s Kitchen bathroom with a stranger.

Gray eyes flick upward.

Assessing and predatory.

His fingers trace the front of Erwin’s shirt once, almost absentmindedly, before his mouth curves into something wicked and amused.

“Now,” he murmurs, “let’s see if you’re as interesting as you look.”

Erwin’s breath hitches. His mouth turns dry as Dante unbuckles his belt and swiftly pulls his extremely hard and neglected cock out of his boxers.

“Fuck,” Erwin puts both hands against the wall of the bathroom stall. “You don’t waste any time, do you?”

Dante mutters something about the size of Erwin’s dick before wrapping his lips around it and taking it almost all the way down his throat like he’s done this before.

“Oh my god,” Erwin’s head falls back as he stifles an embarrassing moan. Erwin’s fingers tighten instinctively in Dante’s dark hair, not enough to hurt, just enough to ground himself against the violent rush of sensation and bourbon and bad judgment. The cramped stall suddenly feels far too small.

“Fuck,” he manages, voice rough enough not to sound like his own.

Dante glances up.

That’s somehow worse.

His grey eyes are steady, unreadable except for the faintest gleam of satisfaction, like he knows exactly what effect he’s having on Erwin and intends to exploit every second of it. There is no embarrassment in him. No hesitation. Just control wrapped in sharp edges and dangerous calm.

Erwin swallows hard.

“Jesus,” Erwin breathes again, half-laughing at himself now, flushed and thoroughly compromised. “You do this with all your fake import-export clients?” His cock twitches as Dante drags his tongue under the sensitive skin.

Dante pulls back just enough to smirk. Lips glistening with spit and precome.

“Still talking, detective?”

The sarcasm lands like a spark against gasoline, and Erwin is about to speak again when Dante takes him into his mouth again, this time apparently determined to finish the job.

Erwin has to bite down on his knuckle to stop himself moaning out loud. It’s embarrassing how much he enjoys this. How good it feels.

The sounds themselves are obscene. Sloppy, wet noises mixed with the slow murmur of bass from the bar.

He looks down at Dante, eyes looking up at him and Erwin grabs his chin while he feels more and more drunk by the scene before him.

For a moment he slowly fucks Dante’s mouth, pushing himself further down his throat and Dante, smug fucker, glances up at Erwin again. Tears start to form in the corner of those grey eyes, he chokes a little and Erwin loses it. He comes hard down Dante’s throat and the man on his knees–just takes it.

For a moment it feels like his knees will give out. Dante pulls off, gasps a little before he stands back up and grabs Erwin by his jaw and makes him taste himself on Dante’s tongue.

For several seconds, Erwin can do nothing except breathe.

His hands remain braced against the stall wall, knuckles pale against chipped paint, pulse still pounding hard enough to make the fluorescent lights seem too bright. The bourbon in his system turns everything warm and unsteady around the edges. Dante stands there, while Erwin pulls his pants back up and makes himself decent. 

Erwin turns his head just enough to glare at him.

“You are profoundly smug.”

Dante adjusts Erwin’s collar, expression unreadable except for the faint upward twitch at one corner of his mouth.

“And you’re surprisingly loud for a detective.”

“That is deeply unfair.”

“But deeply accurate.”

Erwin huffs out something halfway between a laugh and a complaint.

Up close, Dante still looks infuriatingly collected. Hair slightly disordered, lips a little swollen, shirt rumpled in a way that makes him somehow even more dangerous-looking. But beneath the surface there’s something else—something measured. 

Not drunk enough, Erwin thinks.

Or perhaps drunk in a very disciplined way.

“You’re staring again,” Dante says.

“I’m reassessing.”

“Oh yeah?”

“You gave me a fake name.”

Dante shrugs.

“You accepted it.”

“That isn’t the same thing.”

“No?” Dante steps closer, just enough to crowd Erwin back into the stall wall again. “You seemed very trusting ten minutes ago.”

Erwin laughs despite himself.

“Arrogant bastard.”

“Detective.”

Erwin studies him openly now.

The sharpness of his jaw. The cool intelligence in those gray eyes. The way his breathing has already settled. The complete absence of awkwardness.

Most men after a bathroom encounter with a stranger would at least pretend embarrassment.

Dante looks like he’s already mentally halfway into tomorrow.

“Who are you?” Erwin asks.

“Still Dante.”

“Liar.”

“Possibly.”

The answer comes too easily.

Then Dante glances toward the bathroom door, expression shifting by degrees so small another man might miss them.

Without another word, he reaches past Erwin, unlatches the stall, and steps out.

“That’s it?” Erwin asks, following him to the sinks. “You destroy my night and then vanish?”

Dante washes his hands thoroughly, which Erwin finds absurdly attractive for reasons he refuses to examine.

“Your night looks very intact.”

“Debatable.”

Dante dries his hands.

Erwin watches him in the mirror.

“Will I see you again?”

That earns a pause.

Dante looks at him through the reflection rather than directly.

“Hopefully not,” but there’s a faint smile on his lips, gone almost immediately. “Goodnight, detective.”

And then he’s gone.

No dramatic exit. No backward glance. Just the quiet click of the bathroom door and absence.

Erwin stays where he is for a moment longer, breathing through the lingering bourbon heat and trying to collect what remains of his judgment. The fluorescent light overhead hums faintly, ugly and relentless, revealing every detail he would rather ignore.

His shirt is wrinkled. His tie sits crooked around his neck. His mouth feels bruised.

He looks exactly like what he is; A detective who just let a stranger with a fake name blow him inside a bathroom stall.

Erwin exhales sharply, drags a hand over his face, and stares at his reflection.

The detective in him starts waking up again in fragments.

Dante had handled intimacy with unnerving ease, as if closeness itself presented no vulnerability whatsoever. As if trust was irrelevant.

That thought leaves Erwin colder than the sink water.

“Fantastic,” he mutters.

He fixes his collar as best he can, splashes cold water over his face, and leaves the bathroom.

The warmth and noise of the bar hit him immediately.

Music.

Laughter.

Glasses clinking.

The bartender spots him almost at once and waves him over with unmistakable amusement.

“Hey, detective.”

Erwin approaches, still half distracted.

“What?”

The bartender slides him something on the bardisk.

Erwin blinks and a very unpleasant chill crawls through him.

His wallet and badge.

“The short guy said you dropped it?”

Erwin takes the wallet immediately, checks it on instinct. Badge still there. Cards untouched. Cash intact.

He hadn’t even noticed it missing.

There’s a neat and sharp handwriting inside the napkin.

You should be more careful with your badge, Detective Smith. Someone dangerous could have found it.

A second line underneath.

Also, you talk too much.

Erwin stares at the note. He hadn’t told Dante his last name.

Then he slowly looks toward the front door, toward rain-smudged windows and the restless black city beyond.

He replays the entire beginning of his night differently now.

Dante’s gaze catching details and deflecting.

The way he moved with the complete absence of hesitation. And the fact that at some point, in that cramped bathroom stall, the man had lifted Erwin’s wallet without him noticing.

Not theft. A demonstration. A message.

Erwin was never the one in control here.

Erwin folds the napkin carefully and slips it into his pocket.

Whoever Dante really is, he is not a bored logistics manager looking for a one-night distraction.

And Erwin, against all common sense, wants to know exactly what kind of dangerous man he just let put his hands on him.
