I wake up warm.

This is the first problem.

The second problem is the arm around my waist.

The third is that I know whose arm it is before I open my eyes, because I know the weight of it, and the exact place her wrist rests against my hip, and the way her breath moves the hair at the back of my neck. I know all of it. I've known it for six hours.

Oh.

Right.

We did that.

Several times, actually.

Excellent.

The room is that gray-blue that only exists at five-something in the morning, before the curtains decide to commit. The air-conditioning ticks. Somewhere down the hall a cart rolls past, ice buckets clinking, and I lie very still and do the math. Whiskey. Elevator. The door closing. Her mouth. All of it stacked behind me like a receipt I'm too scared to read.

I turn.

She's on her side, one arm still flung across the space I just left, hair a black spill across the pillow. No makeup. No posture. No cataloguing. Her face is slack and young and she has a crease pressed into her cheek from the pillowcase, and I have never in two weeks seen Vivienne Ashford look like anything other than a verdict.

She looks like a person.

It's worse than the sex.

Her eyes open. They go wide for half a second — pure animal startle — and then find me, and everything comes back into them at once. The bar. The elevator. My hands. Her own voice saying this is a bad idea while she pulled me through the door.

She doesn't move her arm.

"Our parents are getting married today," she says.

"In six hours."

I twist to look at the clock on the nightstand. Red numbers, the kind that judge you.

"Five and a half."

"Fuck."

"Yep."

Neither of us moves. Her arm is still there. I can feel her pulse through her wrist against my hip, slow, steady, a metronome that has no idea what it's keeping time for.

"You said it couldn't happen again," I say.

"I recall."

"So this is — what, a violation?"

Vivi's mouth does something. It's not a smile. It's the thing that happens to her face right before one.

"Technically," she says, "this is the same occasion. The night hasn't ended. It's — contiguous."

"Oh my God."

"It's a defensible reading."

"You're trying to loophole sex."

"I'm trying to be accurate."

I laugh. It comes out of me before I can stop it, low and surprised, and her eyes change when she hears it — the way they always do, like she's filing it somewhere she doesn't want me to see. Then she pulls me in by the waist and kisses me, and the laugh goes somewhere else entirely.

This is different.

Last night was whiskey and adrenaline and the specific violence of two weeks of not doing something. Fast. Half-dressed. The lamp still on because neither of us thought to turn it off. This is slow. She takes her time with my mouth like she's memorizing it, and I have the horrible, clear thought that I could do this on a Tuesday. That this isn't a night. This is a thing I would want on an ordinary morning with nothing wrong in the world.

Her hand slides down my back, palm flat, all the way to the base of my spine, and presses. I make a sound against her mouth. She swallows it.

"Say it," she says.

"Say what?"

"That you want this. Sober. In daylight."

"It's not daylight."

"Charlie."

I open my eyes. Hers are right there, blue and steady and absolutely terrified, and I understand that this is the actual question, that last night could be filed under anything — whiskey, grief, the wedding, the general catastrophe of being twenty-one — and that what she's asking me to do is remove every exit from the room.

"I want this," I say. "Sober. Whatever this is."

"Good."

She kisses me again, and this time she doesn't stop, and the sheet gets twisted around one of my legs, and at some point she rolls me onto my back and gets her thigh between mine and I say her name, and she says mine back like it's an answer.

Afterward I'm on my stomach, face half in the pillow, and she's drawing something on my shoulder blade with one finger. Circles. Slow. I don't know if she knows she's doing it.

"You know this changes nothing," she says.

"Sure."

"I mean it. We have a wedding. We have — families. This is a logistical impossibility."

"Absolutely."

Her finger keeps circling.

"You're agreeing too fast," she says.

"I'm agreeing at the correct speed."

"That's not a phrase."

"It is now. It's in the loophole."

She huffs — that little exhale that's the closest she gets to losing — and I turn my head to look at her. She's propped on one elbow, hair everywhere, sheet up to her ribs, and she looks at me the way she looked at me across the reception hall a week ago, except now there's no room full of people between us. Just the gray light and the ticking air-conditioning and my own heartbeat, which has apparently decided to be loud.

"I should go," I say.

"You should."

Neither of us moves.

"Four doors," I say.

"I know how many doors."

Of course she does. She catalogued the hallway the first night. She probably knows which floorboards creak.

I sit up. The sheet goes with me. My dress is on the floor by the desk, and one shoe is somehow by the bathroom door, and my bra is hanging off the arm of the chair like it gave up. I start collecting things and I can feel her watching me the whole time, and I do not look at her, because I have a suspicion about what my face is doing.

"Charlie."

"Mm."

"Breakfast."

I turn around. She's still in bed, sheet up, chin on her knee, and she's not asking it like a question.

"Are you asking me to breakfast?"

"We eat breakfast every morning."

"Vivi. We just —"

"We eat breakfast every morning," she says again, evenly. "I don't see why today would be different."

And there it is. The whole thing, in one sentence. She's not offering me a morning after. She's offering me a Tuesday. She's offering me the drive to campus and the coffee order and the mug she washes first, and she's saying it in that flat, decided voice she uses for seating charts and tennis reservations, and it lands harder than anything she said in bed.

"Okay," I say.

"Okay."

I get dressed in the bathroom. The mirror is unforgiving. There's a mark on my neck I'll have to deal with, and my hair is a crime, and I stand there for a second with my hands on the cold sink and think, very clearly: you are going to do this again.

I don't know if that's a warning or a plan.

When I open the door she's up, in the hotel robe, pouring water from the little glass bottle into two cups. She hands me one without looking. Our fingers don't touch. It's the most deliberate non-touch I've ever received.

"Twenty minutes," she says. "The restaurant. Don't be late."

"I'm never late."

"You're late to everything."

"I'm late to things that don't matter."

She looks up at that. Something moves behind her eyes and gets put away.

"Go," she says.

I go.

The hallway is longer than it was last night. Four doors. I count them anyway, because I'm an idiot, and because I want to know exactly how far it is, and because when I get to my own door I stand there with the key card in my hand for a second too long, and I realize that the thing I don't want to do is open it.

Because opening it means the night is over.

I open it. The room smells like nothing. My garment bag is hanging on the back of the door, burgundy, zipped to the chin. The little plastic clock says 6:14. I shower, and I put on jeans and a sweater, and I deal with my hair as best I can, and I check the mirror twice for the mark on my neck and cover it with concealer and then check again.

Then I go downstairs and eat breakfast with my stepsister.

The restaurant is all white linen and windows. Half the wedding party is already down — aunts, an uncle, two of Cate's friends from the city in matching sunglasses — and Vivi is at a table by the window with two coffees in front of her, and she has already ordered mine the way she orders it, which is to say correctly, which is to say with oat milk and one sugar and no ceremony about it at all.

I sit down across from her.

"Stop staring," she says, without looking up from her phone.

"I'm not staring. I'm observing."

"You're staring."

"Observational staring."

She sets the phone down and picks up her cup, and I watch her mouth close around the rim, and I have to look out the window at the parking lot, which is a beautiful parking lot, an incredible parking lot, the finest parking lot I've ever seen.

It is genuinely astonishing, the new information I have. I know what she sounds like when she's not being careful. I know where she's ticklish. I know that she says my name differently when she's about to come than she does in a car at seven in the morning, and I know that I am now the only person at this table — at this entire wedding — who knows that, and the knowledge is sitting in my chest like a swallowed stone.

She looks up.

I look away too late.

"You're doing it again," she says.

"Doing what?"

"That thing with your face."

"I have one face."

"You have several. That's the problem."

And then Cate arrives.

"There are my girls!"

I inhale coffee. It goes down the wrong pipe and I spend four seconds coughing into a napkin while my mother pulls out the chair beside me in a cloud of gardenia and glossy hair, and when I surface, Vivi's face has gone completely blank in a way I have never seen it go blank before. It's not composure. It's the absence of composure, painted over fast.

"Good morning," she says.

"Good morning, darling." Cate signals a waiter without looking at him. "Did you both sleep well?"

"Great," I say.

"Fine," Vivi says.

Under the table, her foot finds my shin. It's not a kick. It's a warning shot. I kick her back and hit her ankle, and she doesn't flinch, and the waiter brings Cate a cappuccino and she stirs it and beams at us both with the full wattage of a woman who has never once suspected anything in her life.

"I was up at five," Cate says. "I couldn't sleep. I kept going over the seating — Diane called about the readings, and the flowers are apparently arriving at ten, and I still haven't decided about the second reading, so if either of you has a preference, speak now."

"Whatever you want," I say.

"That's not helpful, sweetheart."

"Corinthians," Vivi says. "The one about love being patient. Your mother's already read it twice at other weddings, though, so it might feel recycled."

Cate stares at her. Then she laughs, delighted, and reaches over and squeezes Vivi's forearm.

"You are so like your father. He knows everything about everyone's weddings too." She sits back, radiant. "I'm just so happy you two found each other."

Vivi's coffee cup pauses halfway to her mouth. It's a quarter of an inch of movement and I notice it, because I now notice everything about her, which is a development I did not consent to.

"Really," Cate goes on, "I was so worried. Moving into that house, and you two barely knowing each other, and I thought — well. But look at you. Breakfast together. Every morning. You'd think you'd been sisters for years."

I feel Vivi's foot go still against mine under the table.

"Mom," I say.

"What? It's a compliment."

"It's a lot of sentences."

"I'm a woman of many sentences." She checks her watch and stands, gathering her bag. "I have to go — the florist, the florist, the florist. Charlie, hair at two, do not be late, I have already told them you're difficult."

"I'm not difficult."

"You're my daughter. You're difficult." She kisses the top of my head, then — after a half-second's hesitation — reaches over and squeezes Vivi's shoulder too. "Help her, won't you? You're so good at this."

Then she's gone, heels clicking across the marble, and the table is very quiet.

I set down my cup.

"Found each other," I say.

"Don't."

"She's not wrong."

Vivi looks at me. For the first time this morning, her face does something unguarded — a flicker, there and gone — and then she picks up her phone and stands.

"Two o'clock," she says. "Don't be late."

"I'm never —"

"Charlie."

"Fine."

She walks out with her coffee and her straight back and does not look at me once, and I sit there in the white-linen restaurant with the finest parking lot in the world outside the window and finish my coffee alone, and my phone buzzes, and it's her.

Stop smiling.

I look up. She's at the door, phone in hand, not turning around.

I put my phone face-down and I do not stop smiling.

—

Getting ready is a war conducted by three women with brushes.

The suite smells like hairspray and cold cucumber. My mother is in the chair by the window in a silk robe, one leg crossed over the other, a mimosa going warm on the armrest, and she is the calmest person in the room. I'm in the other chair with a woman named Renata doing something violent to my hair while another woman does my nails and a third, whose name I never catch, keeps handing me things to hold.

"You're fidgeting," Cate says.

"I'm being held hostage."

"You're fidgeting." She watches me in the mirror. "Are you nervous?"

"It's your wedding."

"Yes." She smiles at her own reflection, and it's a real smile, a young one, and something in my chest twists. "Fourth time's the charm."

"Mom."

"What? I'm allowed to joke. It's my wedding."

Renata pins something and I hold still. In the mirror, my mother is looking at me the way she looks at paintings at auction — assessing, fond, slightly hungry.

"You look beautiful," she says.

"I'm in a robe."

"You look beautiful in a robe." She reaches over and pats my knee. "I'm glad you're here. I know this year has been — I know I've dragged you around a bit."

"A bit."

"A bit." She says it gently, and I let it go, because it's her wedding, and because the alternative is a conversation I don't want to have in front of Renata. "But I'm glad. I'm glad you're here. And I'm glad you and Vivi —" She stops. She's not looking at me now; she's looking at her own hands. "I just want this one to be the one, Charlie."

"I know."

"Do you?"

I meet her eyes in the mirror.

"I know," I say. "And I think it is."

And I mean it, which is the strange part. I mean it entirely, and I'm sitting in a chair getting my hair done with a bruise on my neck and my stepsister's number at the top of my messages, and both things are true at once, and I don't know what to do with that.

—

The ceremony is at four.

I see Vivi in the hallway outside the conservatory at ten of. She's in a black gown — of course she is, of course she's wearing black to her father's wedding, of course it looks like that — and her hair is up, and there's a single silver line at her throat, and she's standing with Alexander, who's in his tuxedo and laughing at something she just said, and she's laughing back, the real one, the rare one, and I stop in the middle of the hallway like an idiot.

She turns. Sees me. And her face does the thing — the flicker, the unguarded quarter-second — and then it closes, and she looks at me the way she'd look at anyone, and I do the same, and Alexander turns and beams.

"Charlie! There she is." He crosses the hall and takes both my hands. "Your mother looks — I've never seen her like this. Have you seen her?"

"I've seen her."

"She's a miracle. Your family's a miracle." He's beaming, and his eyes are wet, and he is genuinely, completely happy, and I understand, standing in the marble hallway in my burgundy dress, that I'm about to stand in a room and watch this man promise my mother forever while his daughter watches me from six feet away with everything we did last night behind her eyes.

"Go," he says. "They're seating. Go on."

Vivi walks past me toward the doors. She doesn't slow down. She doesn't look at me. But as she passes, low enough that only I can hear:

"You're staring."

"I'm observing."

"Later."

And then she's through the doors, and I'm left standing in the hallway with my hands at my sides.

Later.

—

My father is early.

He's sitting in the third row on the aisle, in a gray suit, checking his watch — but he's there, fifteen minutes before it starts, and when he sees me his whole face opens up.

"Charlie."

"You're early."

"I said I would be." He stands and hugs me, and he smells like his cologne and coffee, and I hold on a half-second longer than I meant to. "You look —" He steps back. "You look like your grandmother."

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

"Don't let it go to your head." He glances toward the doors. "Your mother's happy."

"She is."

"Good." He says it quietly, and there's something underneath it that I don't pick at, because it's four o'clock and the music is starting and the guests are turning around.

I take my seat in the front row. Across the aisle, Vivi takes hers.

The doors open.

My mother comes down the aisle in ivory, on Alexander's arm — no, on no one's arm, she insisted, she walks herself — and she's crying before she hits the first row, and Alexander is crying before she reaches him, and the officiant, Diane, says the words about two families becoming one, and I look at Vivi.

She's looking at her father.

Then she looks at me.

At four o'clock, nothing about her actually changes. She's still Vivienne Ashford. She's still sitting across the aisle with her hands folded and her chin level and her mouth doing nothing in particular. The ring goes on my mother's finger. The papers are signed. Diane says I now pronounce you and the room stands up and claps, and Alexander kisses my mother, and Cate laughs into his shoulder, and everyone is happy.

Only the word changes.

That's the thing I can't stop thinking about, standing there clapping with my hands stinging. We walked into this room as two people whose parents were getting married. We walk out as sisters. Nothing else moved. And yet everything is different, because now there's a word for what we're not, and it's a word we both have to say out loud for the rest of our lives.

She catches my eye across the aisle.

She doesn't smile. She just holds it — one second, two — and then turns to her father, who is hugging her, and I turn to my mother, who is hugging me, and we are both, briefly, exactly where we're supposed to be.

—

The photographs start at four forty-five, on the terrace, with the light going gold.

The photographer is a woman named Priya's cousin, or maybe Cate's friend, or maybe someone's — I've stopped tracking. She's efficient. She arranges the wedding party, then the families, then the couples, and then she gets to us.

"The daughters," she says. "Together, please. By the railing."

Vivi and I walk to the railing. The terrace is warm. Somewhere behind us a string quartet is playing something that sounds like a movie about Italy. The photographer raises her camera, frowns, and lowers it.

"Closer together."

We step closer.

"Closer."

We step closer. My shoulder is almost touching hers. I can smell her perfume — the same one, the one I could pick out of a hundred, the one I've been smelling in my sleep for a week.

The photographer tilts her head.

"Vivienne — hand at Charlotte's waist."

There's a pause. It's a quarter of a second. Nobody in the world would notice it except me, and I notice it because I've spent two weeks learning to notice everything about this woman, and because last night that hand was on my waist in an elevator, and this morning it was on my waist in a hotel bed, and now it's going to be on my waist in a photograph that will hang in a house we both live in, and everyone we know will look at it and see two sisters.

Vivi's hand comes to rest on my waist.

It's the same place. Exactly the same place. Her fingers settle into the curve of my hip like they've been assigned there, and there is nothing innocent about either of us knowing precisely how that touch feels, and there is nothing I can do about my face, which I can feel doing something I don't want it to do.

"Perfect," the photographer says. "Now look at me and smile."

I look at the camera. I smile.

Vivi's thumb moves — half an inch, once, against my dress — and then goes still.

The shutter clicks.
