Girls Night Out
Lin looked up from the couch when I came back home.
She blinked.
“What are you wearing?”
I looked down at myself.
“Clothes?”
“Those are not your clothes.”
“They are now.”
The black pleated skirt sat high on my waist, sharp and structured. The grey shirt was tucked in cleanly, sleeves rolled to the elbows, patterned tie sitting exactly where Leah had left it.
Lin stood and came closer.
“You look...”
“Good?”
“Professional.”
“Eww.”
“Stylish professional.”
“Better.”
She touched the end of the tie.
“Leah did this?”
“She said I normally dress like I don’t care what anyone thinks of me.”
Lin smiled.
“She is very blunt.”
I sat beside her.
“Sooooo ... Leah wants to take us out tonight.”
Lin’s smile faded slightly.
“Us?”
“Girls’ night. Drinks. Expensive ones.”
“I don’t know.”
“Why not?”
She shrugged.
“I barely know her.”
“That is generally how knowing people starts.”
“You know what I mean.”
I did.
Leah had arrived quickly and somehow taken up a lot of space without technically asking for any of it. Lin was still watching her, and me with her.
“She’s really not that bad,” I said.
Lin gave me a look.
“She told me my karaoke performance had excellent visual potential and then criticised the angle you filmed it from.”
“The angle was bad.”
“That is not the point.”
“She’s lonely.”
Lin looked at me again.
I pressed on.
“She just moved here. Her apartment is full of boxes. She has work people and her parents’ friends, but she doesn’t actually have friends.”
“She has you.”
“Exactly. That’s how desperate things are.”
Lin laughed despite herself.
“Come on. Please?”
“Mia.”
“She needs a proper night out. No donors, no rich old people, no pretending to care about museum apps. Just us.”
“You really want me there.”
“Yes!”
That came out too quickly.
Lin studied me.
I leaned against her shoulder.
“Please, Lin.”
She sighed.
“You’re doing the voice.”
“What voice?”
“The one where you’ve already decided I’m coming and you’re making me feel guilty until I agree.”
“I would never do anything like that!” I said in a mock-shocked voice.
“You are currently leaning on me like an abandoned dog.”
I leaned harder.
She sighed again.
“Fine.”
I lifted my head.
“Fine?”
“I’ll do it for you.”
“Yay!”
I grabbed my phone before she could change her mind.
Me:
Lin said yes.
The response came almost immediately.
Leah:
Excellent.
Leah:
I’ll collect you both at eight.
Me:
Collect?
Leah:
I don’t want you to get lost.
I showed Lin the screen.
She stared at it.
“I already regret this.”
“You said yes.”
“I said I’d do it for you.”
I smiled.
“Still counts.”
At five to eight, our group chat lit up.
Leah:
Come down.
Lin crossed to the window and pulled the curtain aside.
“No one is there.”
I stood and reached for my shoes.
“Trust in the system.”
Lin looked back at me.
“What system?”
“The Leah system.”
“That is not reassuring.”
I slipped my shoes on and headed for the door.
Lin threw both hands into the air.
“Fine. Apparently we’re obeying vague commands now.”
She followed me downstairs.
The moment we stepped outside, a black Uber rolled up to the curb.
Before it had fully stopped, the driver got out and opened the rear door.
I grinned and climbed straight in.
Lin stopped on the pavement.
“How do you know this is for us?”
I leaned back toward the open door.
“Trust the system.”
Then Leah’s voice came from inside the car.
“She’s learning.”
Lin climbed in more cautiously than I had.
The back was larger than the car Leah and I had taken the night before, with two pairs of leather seats facing each other. Leah and I sat facing backward. Lin lowered herself onto the opposite seat and looked around.
She wore a short black skirt, dark tights and ankle boots, paired with a soft green top that made her look warm and approachable. Her hair was loose, and she had put on just enough makeup to prove she had considered the evening.
Beside me, Leah looked like she had planned the entire night around being observed.
Tailored black trousers. A silver-grey top with one bare shoulder. Pointed black heels. A small structured bag. Sharp eyeliner. A dark lip.
I sat between them in my black pleated skirt, grey shirt and patterned tie, wearing the best outfit I owned because Leah had selected every part of it.
Lin ran one hand over the leather seat.
“This is very fancy.”
“It’s an Uber Black,” I said, with the authority of someone who had now used one twice.
Leah smiled at me.
“No expense spared tonight. We stumbled into some funds, and they should be used to cleanse the palate. They came from a very dirty source.”
Lin looked between us.
“Are you two selling drugs?”
“No,” I said.
Leah crossed her legs.
“Nothing that respectable.”
The Uber dropped us off in Koreatown outside a restaurant with dark windows, brass lettering and a woman at the door holding a tablet.
“Reservation for Takahashi,” Leah said.
Of course she had a reservation.
My girl’s planning skills remained unrivalled.
We were led past the main dining room to a curved booth near the back. Leah took the outside seat, Lin slid in beside her, and I sat opposite them.
Drinks appeared first. Leah ordered several dishes for the table after checking whether Lin ate anything she disliked.
Then she started asking questions.
Not interrogation questions. Not the kind designed to expose an embarrassing answer or give her material for later.
She asked about Lin’s family. Which art periods of history she liked. Whether she preferred art because of the work itself or because of what it revealed about the people who made it. What brought her to New York. What kind of music she listened to when nobody else was around.
Questions that gave Lin somewhere to go.
And Lin went.
At first, her answers were careful and short. Then Leah found the right thread and pulled gently.
Lin told her about a professor who could turn any lecture into an argument about colonial theft. She complained about museum labels that pretended objects had simply appeared in Europe through natural migration. Leah asked a follow-up that proved she’d actually listened rather than simply waiting for her turn to speak.
Lin smiled.
Then she did it again.
She laughed at Leah’s jokes. Real laughs, not the polite little ones she used when she wanted a conversation to end without hurting anyone.
Leah never put me down for an easy laugh. Never used something I had told her privately to make herself look clever. She did not push Lin toward anything she was not perfectly happy to share.
She simply kept the conversation moving and made space whenever Lin wanted to fill it.
I sat across from them feeling stupidly pleased.
My best friend and my new...
Friend?
Idol?
Potential lover?
Whatever Leah was becoming, she and Lin were getting along.
That was what I had wanted.
Wasn’t it?
Lin said something that made Leah laugh, her head tipping back slightly. Then Leah leaned closer and asked another question, and Lin turned toward her without looking at me first.
A small, ugly thing shifted inside my chest.
I took a drink and pushed the feeling back down.
This was good.
They were bonding.
I had made this happen.
Under the table, Leah’s hand settled on my thigh.
She kept looking at Lin. Kept listening as Lin spoke. Her expression did not change.
Her fingers squeezed my leg once.
Firm. Brief.
Don’t worry, Mia.
The ugly thing loosened.
I reached for another piece of food, trying not to smile too obviously.
Leah was still talking to Lin.
But she knew exactly where I was.
When the last plates were cleared, Leah checked the time.
“I booked us a room next door.”
“A room?” Lin asked.
“For karaoke.”
I looked at her.
Karaoke.
For the first time that evening, I wondered if Leah had made a mistake.
Dinner had worked because Lin could talk. Because Leah could ask questions and listen and make everything feel easy.
Karaoke was different.
Karaoke required standing up in front of people and choosing to be heard.
Even if the people were only us.
I followed them next door, trying to decide whether this was the first crack in the Leah system.
The room was private, with a curved leather sofa, two microphones and a screen covering most of one wall. Drinks were already waiting on the table.
Leah picked up the tablet and handed it to Lin.
Lin stared at the song list.
Then she scrolled.
Her expression changed.
“Wait.”
She scrolled again.
“They have this?”
Leah sat down and crossed her legs.
“I asked.”
Lin looked up.
“How did you know I liked them?”
“I asked Dan.”
I turned toward her.
“You interviewed Dan?”
“I asked him several efficient questions.”
“You researched us.”
“I planned an evening.”
Lin kept scrolling, finding one song after another.
Not generic choices. Her songs. Bands she had mentioned before, albums she still listened to, songs Dan had apparently remembered because he was occasionally useful.
Then I took the tablet.
Leah had filled my section with pop songs from when I was fifteen to twenty. Music I would never have claimed to know.
Except I did.
Every chorus was still buried somewhere inside me. Every stupid line from songs that had played in shops, at parties, in taxis, through other people’s headphones.
Music I did not know I knew until the opening notes started.
“You built a trap,” I said.
“God forbid a girl plan an evening without being accused of treachery?”
“This playlist is devilishly perfect.”
“And that is bad?”
Lin broke the awkward silence by choosing the first song. She tapped the table a few times, and I caught the title “Before He Cheats” just before the music started.
She started cautiously, sitting down with the microphone held in both hands. By the chorus she was louder. By the end she was standing.
Then Leah handed me the other microphone before I could object, and the next song, “You Oughta Know”, stumbled out of me. Words that had apparently survived untouched for fifteen years.
I knew all of it.
Not well.
But completely.
Leah watched us with the satisfied expression of someone whose experiment had produced the correct result.
Then it was her turn.
Leah grabbed my mic and spun it in her hands like a baton. She selected a song from the board, looked at us and said into the microphone, “This is gonna get loud.”
A guitar riff started. She bounced back and forth a few times, before stopping in a wide stance, lifting one hand into the air and screaming,
“OOOOOOOOOOOOOOONNE PUUUUUNCH”
A bald man in a white cape and yellow suit punched the screen, as the lyrics started, and Leah ignored it completely.
There was no hesitation.
No warm-up.
She hit the first line cleanly and at full volume. Then the lyrics switched to Japanese.
Leah didn’t seem to notice.
She moved through the song like she had rehearsed it for a stage rather than a padded room above a bar.
Her pronunciation was sharp. Her timing was perfect. She even knew where to breathe.
Lin stared at her.
I stared harder.
Of course she could sing.
Of course Leah had anime opening themes prepared.
When the song ended, Leah gave a small bow.
Lin clapped.
I pointed at her.
“You have done this before.”
“Once or twice.”
Lin laughed, “That sounds like an understatement.”
“At my peak, I did karaoke twice a week for five years at university.”
“Competed?”
“Occasionally.”
“How did you do?”
Leah sighed dramatically, held up two fingers in a V-sign beside her cheek and gave the most deadpan kawaii pose imaginable.
“Regional champion twice.”
Lin blinked.
Mia stared.
Leah dropped the pose.
“It sounds much more impressive than it was.”
She selected another song.
Something Blue.
It started slower.
Then she started moving.
I’d seen Leah dance before.
This wasn’t dancing.
Every movement hit the beat. Every glance matched the lyrics. She leaned into the imaginary camera at exactly the right moments, snapped her head with the chorus, played to an audience of two.
It felt less like karaoke and more like watching someone perform on stage.
Lin looked at me.
I looked back.
Neither of us had anything to say.
She finished with the same impossible precision.
Leah hadn’t booked karaoke because she hoped we’d enjoy it.
She had made sure we would.
More drinks arrived. More songs were sung. By the end, we were all dancing.
Eventually Leah checked the time and set down her microphone.
“We need to wrap up. I have somewhere else booked.”
Lin groaned.
“We just got good.”
“We got loud.”
“That is what good sounds like.”
Leah smiled and picked up the tablet.
“One last song.”
Leah selected one final track and tossed the second microphone to Lin.
“Rap battle, bitch.”
A heavy bassline filled the room.
Then the speakers shouted,
“There’s some whores in this house!”
Lin lit up.
Not smiled.
Lit up.
She actually bounced once before snatching the microphone out of the air.
Leah watched her with the satisfied little smile of someone who had selected exactly the right weapon.
Then she looked at me and winked.
Lin launched into her verse with alarming confidence, enthusiastically making demands that would have gotten her disowned back home.
Leah drained the rest of her drink, waited for her cue, then answered with equal enthusiasm, firing the lyrics right back like they were arguing over whose standards were more outrageous.
I just stared.
Twenty minutes ago, these two had been discussing museum ethics over Korean barbecue.
Now they were aggressively rapping increasingly filthy boasts at each other with the conviction of lifelong rivals.
Neither missed a beat.
Neither even cracked a smile.
When the song ended, Lin collapsed onto the sofa, breathless.
Leah collected the microphones.
“Good. Now we can go somewhere respectable.”
Lin stared up at her.
“After that?”
Leah opened the door.
“Especially after that.”
A new Uber Black rolled up just as we stepped out of the karaoke bar.
Lin stopped on the sidewalk.
“We can take normal Ubers, you know. We are not royalty.”
“Today we are,” Leah said.
The car carried us across town and dropped us in front of two steel doors set into a huge concrete block of a building.
No sign. No windows. Nothing that suggested music, drinks or people having fun inside.
Lin looked up at it.
“What is this?”
“Exclusive,” Leah said.
“That is not an explanation.”
“It is the important part.”
Leah stepped out of the car and walked toward the steel doors.
Two men stood beside them in black suits.
Neither looked like a nightclub bouncer. They were too still for that. No folded arms. No scanning the street. No visible interest in who arrived.
One of them held out a small black scanner.
Leah opened something on her phone.
A QR code appeared.
He scanned it.
A soft tone sounded.
Then he looked at her.
“Passcode?”
Leah looked him in the eye.
“Orchid.”
The man said nothing.
No nod or confirmation.
The second guard opened the steel door.
That was apparently enough.
We stepped inside.
The door closed behind us with a heavy metallic sound.
The music reached us first as pressure.
A deep bass pulse moved through the walls and into my chest before I could properly hear the song.
The entrance corridor was painted dark red.
Not bright red.
Dried-blood red.
Low strips of light ran along the floor, barely enough to show where we were walking.
Lin looked around.
“Oh.”
That one sound carried several years of suppressed fantasy.
We followed Leah down the corridor.
The walls were covered in art selected specifically to make normal people uncomfortable. Black-and-white photographs of bodies twisted into impossible poses. Metal masks mounted under red lights. A glass case containing something that looked like a ceremonial knife, though I suspected it was decorative and very expensive.
The farther we walked, the louder the bass became.
Each turn revealed another corridor, another dark alcove, another piece of art that made me wonder whether the building had once been used for interrogations.
Lin was smiling.
Not politely.
Actually smiling.
“This is like Blade,” she said.
“Less blood,” I replied.
“So far,” Leah called back to us.
At the end of the hallway, a woman waited behind a narrow black desk.
She wore a fitted black latex dress with a high collar and a slit running almost to her hip. Long gloves covered her arms. A thin silver chain connected one ear cuff to the collar.
Lin’s eyebrows rose.
Mine probably did too.
The woman looked at Leah.
“Reservation?”
“Takahashi.”
She checked a tablet.
“Three. Private booth, lower floor?”
“Yes.”
The woman stepped out from behind the desk.
“Follow me.”
She turned toward a second set of doors.
The latex caught the red light with every step.
Lin leaned closer to me.
“I think I understand exclusive now.”
The doors opened.
The full weight of the music rolled over us.
Below, the club stretched out in dark levels of red light, black steel and moving bodies.
Leah did not slow down.
The host led us past the bar and onto a raised section overlooking the dance floor.
A bottle sat in ice beside the booth. Three glasses waited on the table.
Lin looked at Leah.
“You booked a table?”
“This is not a drop-in club.”
We had one drink first.
Then the music changed.
Something heavier came through the speakers, all bass and pressure, and Lin looked toward the dance floor.
Her entire face changed.
Not nervous.
Hungry.
She stood before either of us suggested it.
I had expected her to need convincing. Lin usually needed a little push before doing anything that made her visible.
Not here.
She stepped onto the floor like she had been preparing for it her entire life.
Maybe she had.
I knew she had grown up trapped in her parents’ careful little world, watching things like the Matrix, the hidden clubs in John Wick, all those secret places behind unmarked doors where beautiful people did terrible things under expensive lighting.
This was the fantasy.
Not the murder or violence, hopefully.
The rest of it.
The secrecy. The music. The freedom. The sense that normal rules had been left outside with the coats.
Lin moved easily.
No hesitation. No looking around to see whether anyone was watching. She let the music take her and became part of the room like it had been waiting for her.
I followed.
Less successfully.
I had enthusiasm.
Enthusiasm was not the same as rhythm.
Every movement I made felt too large or too late. I became aware of my arms, which immediately made them useless. My hips seemed to be receiving different music from the rest of me.
Lin did not notice.
Leah did.
She moved behind me and placed one hand at my waist.
Then she started dancing with me.
Not beside me.
With me.
She guided my hips into the beat, close enough that I could feel the shape of every movement before I had to copy it. When I went too far, her hand corrected me. When I froze, she moved me through it.
I did not understand how someone knew how to couple-dance on a club floor.
Apparently Leah did.
She kept her own dancing smooth and sexy while somehow making mine look intentional.
People looking at us would not see a woman having a disagreement with her limbs.
They would see Leah wrapped around me, moving us both.
I relaxed against her.
My body stopped trying to solve the music and started following hers.
We kept going until all three of us were sweaty, breathless and exhausted.
Eventually, we all made our way back to the booth and collapsed into the seats. Lin kicked off her boots. I leaned back with my drink pressed against my forehead while Leah somehow managed to sit upright and cross her legs like she had not spent the last hour dancing.
She took a long drink.
“I have ordered alcohol and food to my apartment,” she said. “I vote that we move the party there and wind down.”
Lin turned to look at her.
“You’re inviting me to your place?”
“If you’re afraid I’m going to sexually exploit you, I’m sure Mia will protect you.”
Both of them looked at me.
I rocked my hand from side to side.
Maybe.
Fifty-fifty.
Lin stared at me.
“That is not reassuring.”
“I would definitely object if things got unreasonable.”
“What counts as unreasonable?”
“I’ll know it when I see it.”
Leah smiled into her glass.
Lin pointed at me. “You begged me to come tonight.”
“And look how much fun you had.”
“That is not a defence.”
“It is evidence that trusting me occasionally produces good results.”
Leah stood and collected her bag.
“The car will be outside in four minutes.”
Lin looked between us.
“Did I get a vote?”
“Yes,” Leah said. “You can vote in the car.”
I pushed myself to my feet and held out a hand to Lin.
“Trust the system.”
She looked at my hand, then at Leah walking toward the exit.
“I hate this system.”
She took my hand anyway.
Lin did not object when we arrived.
She stepped out of the car with us and looked up at the building.
“You live here?”
Leah headed toward the entrance.
“How rich are you?”
“Corporate pays,” Leah said. “Ask Mia. She can explain it better.”
Lin looked at me.
“Can you?”
“She needs to find a new place in the next six weeks or she’s out on her ass. She is currently paying exactly nothing for this one.”
Leah gave a small grunt of acknowledgement as we stepped into the elevator.
When we reached her floor, there was a delivery cart waiting outside the apartment.
It was loaded with food.
Meat. Fries. Fried chicken. Dumplings. Several other things designed specifically for people who had been drinking and no longer respected their digestive systems.
Beside it sat a case packed with alcohol.
Wine. Spirits. Cider. Beer. Enough variety to survive differing tastes or a minor siege.
Lin looked from the cart to Leah.
“You really don’t do anything half-assed, do you?”
Leah unlocked the door.
“Not tonight.”
We rolled the cart inside, and Leah arranged everything across the kitchen island with military efficiency.
Food on one side. Alcohol on the other. Plates, glasses and napkins lined up between them.
Then she poured three shots.
“What are those for?” Lin asked.
“Bonding.”
Leah pushed a glass toward each of us.
“Bonding time will commence shortly.”
“That sounds threatening,” I said.
“Ah, you pick up on my subtle hints, good. Bonding time will be rewarding.”
We took the shots.
The alcohol burned all the way down. Lin coughed into her hand. I tried not to react, which made my eyes water instead.
Leah opened a cider for herself and gestured at the cart.
“Pick your poison.”
Lin chose wine. I took a cider too, because copying Leah had produced mostly positive results so far.
She placed a large bowl of salty snacks in the middle of the island, then sat across from us.
“So,” she said, folding her hands neatly in front of her. “According to the normal rules of girls’ night, we must now discuss our innermost feelings.”
Lin looked at me.
“Are those the normal rules?”
“I think so. I have seen television.”
“And ideally,” Leah continued, “we will impose some order on them.”
I reached for the snacks.
“You made feelings sound like a difficult project.”
“They usually are.”
Lin took a drink of wine.
“What exactly are we meant to discuss?”
Leah looked between us.
“Everything we normally avoid.”
“I’ll start,” Leah said. “Lin, you get one question. I will answer truthfully, and I will elaborate if you ask.”
Lin leaned forward slightly.
“This is the first free one,” Leah added. “The rest will cost you.”
Lin looked very interested in that offer.
Then she turned to me.
“I’m taking Mia aside first.”
Leah raised one eyebrow.
“To test possible questions,” Lin explained. “In case she already knows the answer. I don’t want to waste this one.”
Leah considered that, then gave a small approving nod and took another sip of cider.
Lin caught my wrist and pulled me a few steps toward the living room.
“Do you know how she has so much money?”
I nodded.
“Kind of.”
Lin narrowed her eyes.
“Kind of?”
“Corporate housing, rich parents, high-paying job. Also apparently museum corruption.”
“Right...”
She thought for a moment.
“What about how she knows all the things she knows?”
I nodded again.
“I kind of know that too.”
“How?”
“Superpowers.”
Lin stared at me.
“That is not an answer.”
“It’s true, though.”
While we were talking, music started playing throughout the apartment. Not loud, but coming from speakers out of sight.
I glanced at Leah, who put her phone away, and continued calmly eating from the bowl of snacks as if she could not hear us.
“Okay,” Lin said. “What about her plans with Dan?”
My eyes went up.
That one landed differently.
I looked back at Leah.
She met my eyes over the rim of her cider.
“No,” I said slowly. “I actually don’t know that one.”
“Okay, Leah. We have one.”
Leah picked up another chip.
“What’s your deal with Dan?”
She paused with the chip halfway to her mouth, then ate it while she considered the question.
“Dan is part of a package deal.”
Lin glanced at me.
Leah continued.
“I know the two of you share him, in a way. I’m not opposed to that. And you both are very attractive and fun to hang out with. If you both have sex with Dan, and I sometimes do too, that does not create a problem for me.”
She took another chip.
“Dan is a great lay, but he is not someone I bring home to my mother.”
Her eyes moved to me.
“Mia is the kind of woman I bring home to my mother.”
Then to Lin.
“And Lin, someone to keep me on my toes. You keep the scale balanced. You are the glue to keep everyone together. Without Lin, everything would fall apart.”
Lin went very still.
“If I had Dan entirely to myself,” Leah continued, “I might sleep with him when I was lonely. Or ovulating. But I would not date him.”
I nearly choked on my cider.
“He is slightly slow on the uptake,” she added, “but he has a kind soul.”
“That is almost sweet,” I said.
“You know it’s true.”
