I arrived home around ten in the morning. I had brought some coffee and bagels from Leah’s hoping that I could talk to Lin over food.
It was always easier to talk when you were eating.
When I entered, I found Leah on the coach scrolling on her phone.
She looked up as I entered and said “Have a good night?”
“One that you would not believe” I replied.
Instant regret filled me suddenly, I did not want to rub Lin’s nose in it.
I quickly changed the subject and said, “Brought Coffee and bagels, you hungry”
Lin jumped out of the couch like a cat that heard the foodbowl rattle.
I gave her one bagel and a coffee and took the other for myself. It was a herb cream cheese beagle with salmon and tomato. I was usually a ham and cheese girl, but trying new things was a goal in itself.
“So...” I started “Made if home just fine?”
Lin took a bite and spoke through the food “Yeah, I still can’t believe she ordered another Uber Black for me, I would have been fine with a normal taxi...”
“I think she is trying to burn off all the money we got, I think she sees it as dirty money and does not want it to go to anything serious, it will taint whatever it goes to.”
“And how much money is she trying to burn?”
I held up my hands and formed a circle “a roll of hundreds about this big?”
“You sure it was hundreds?”
“The top ones were, and it came from a source that does not really care about money, so I don’t expect they would even handle smaller bills”
Lin raised her eyebrows, “Who gave you this money and for what?”
I bit my lip before answering “I can’t talk about who it was, just that it was a very important person, who was caught in a very particular situation, and ... we did a dance for him, and he was impressed”
“A dance where Leah fingers you?”
“Oh right, you know that happened. So yeah, it was a sex thing, not a dance. Anyway, mutual assured destruction, so I can’t talk more about it. I am sorry”
Lin took a sip of her coffee and let out a groan. “This stuff is delicious, where did you pick it up”
“It’s leftover breakfast from Leah’s. She made it for me before heading to yoga.”
“She made you breakfast? And then left for Yoga? That woman sure sends out mixed signals”
I tried to shake my head, but it was more like a side to side movement.
“Leah is a busy woman, I saw her calendar”
Lin took another bite of the bagel. “Oh did you now?”
“Don’t start.”
“I’m not starting anything.”
“You absolutely are.”
She smirked into her coffee.
“So ... how’s our resident relationship guru doing?”
I rolled my eyes.
“She’s not a guru.”
“Really? Because she somehow got both of us questioning our sexuality in under a week.”
I laughed.
“That’s not exactly how I’d describe it.”
Lin didn’t laugh with me. She stared down into her cup for a moment.
“No...”
She let out a slow breath.
“That’s what scared me, Mia. I wanted to stay.”
“I know.”
She shook her head.
“No. I don’t think you do. I didn’t think Leah was dangerous. I thought she was right.”
“Huh?”
Lin picked at the edge of her bagel.
“She understood what I wanted before I did. When she tied my hands, after the blindfolding. It struck a nerve. I did not know I wanted it, until it happened. She understood why I wanted it. And I knew if I stayed, if I let myself go along with it, there was a pretty good chance I’d wake up the next morning thinking every concern I’d had was stupid.”
“Because you’d slept with her?”
“Because I’d adore her.”
I started wondering if I adored Leah. Had she tricked me?
After all, I was eating Leah’s homemade breakfast after spending the night at her apartment.
But she’d told me about this yesterday. The research, the planning, the obsession. Leah didn’t make breakfast because she was trying to get something from me. She made breakfast because somewhere in that ridiculous brain of hers, making me the best possible bagel had become a project.
“She isn’t trying to control me.”
“I didn’t say she was.”
“You kind of did.”
“No. I’m saying I don’t know.”
Lin put her coffee down.
“That’s the problem, Mia. Neither do you.”
“No, Lin. I think I do. I’m not going to share things Leah told me in confidence, but ... she’s lonely.”
I looked down at my bagel.
“And I think she’s working way too hard to make people happy. Me. You. Anyone who asks anything of her.”
I held up the half-eaten bagel.
“I don’t think she made me homemade breakfast because she’s trying to control me. I think she made me homemade breakfast because she’s terrified of letting me down. Or of not being impressive enough.”
I took a big bite.
“Either way, I don’t believe for a second that she wants to control me. She wants me to love her, to be with her, and I think she wants the same thing from you. And that scares you.”
Lin lowered her eyes to the table.
“Maybe.”
She picked at the edge of her bagel.
“I think maybe I’m afraid of loving anyone like that. It feels like being tied down.”
I didn’t interrupt.
“I loved my parents. Kinda. But living with them was a constriction. Their love came with expectations. My love for them made it harder to leave. Everything was tied together.”
She went quiet for a moment.
“Maybe I do love Dan, and I just keep refusing to call it that. Maybe I’m doing the same thing with Leah, except Leah doesn’t make it easy to ignore.”
“And me?”
Lin looked up at me.
“You too, probably.”
“Probably?”
“I don’t know, Mia. Maybe I love you and I’m pushing that away too, because if I admit that I love you, then you have something I can lose.”
My heart sank. I had figured out months ago that I loved Lin, and spent most of that time believing she didn’t feel the same way. Now I was finding out that maybe she did. Maybe she always had, and her stupid love-no-one rule had fucked it all up.
“Okay. So what are our next steps? I plan on spending more time with Leah, and I’d really like you to join me.”
“I don’t think that’s a good idea right now.”
“Why?”
“Because I need to figure some things out, and I don’t think my current self is very good around Leah.”
That hurt more than I expected, but I nodded.
“Okay. Then figure it out.”
Lin looked up at me.
“That’s it?”
“What do you want me to do, assign homework?”
She smiled slightly.
“No.”
“Then take whatever time you need. I’m going to keep seeing Leah. I’m not going to pretend I don’t want you there, because I really fucking do.”
I reached across the table and squeezed her hand.
“When you’re ready, tell me. I’ll bring you back in.”
“And if I’m never ready?”
That one hurt.
“Then I’ll deal with that when we get there.”
Lin squeezed my hand back.
“Okay.”
Three weeks passed.
I didn’t bring up Leah with Lin again.
I did, however, spend three or four nights a week at Leah’s apartment.
The documentary had reached abstract expressionism, which seemed to involve a lot of serious men explaining why paint thrown at a wall was a direct response to nuclear anxiety.
Leah was watching properly.
I was stretched across the couch with my head in her lap, one leg hanging over the armrest. She held a glass of wine in the hand resting against my side, while the fingers of her other hand moved idly through my hair.
Every so often, she made a small sound of disagreement at something the narrator said.
I was mostly on my phone.
I had found Leah’s online handle, Vesper Velvet, and was on her Instagram account. I had fallen far enough down the rabbit hole that I was looking at posts from four years ago. Leah in armour. Leah painted blue. Leah with white contacts and black veins running from her eyes. Leah in a red dress with a sword across her lap, looking like she had already decided the viewer was guilty.
The comments were worse.
Not bad. Just numerous.
People had opinions about her legs. Her mouth. Her hands. One person had written three paragraphs about the way she looked at the camera. Another had apparently been waiting two years for her to remake one particular costume.
I tilted my head back to look up at her.
My girlfriend.
The thought arrived so naturally that I almost smiled.
Then I stopped.
Girlfriend?
We had slept together. More than slept. We cooked together. She had washed my hair once because I had got makeup in it. She knew I hated pulp in orange juice and had bought the right kind without asking.
That was girlfriend stuff.
Friends with benefits probably did some of that too.
But not all of it.
Surely not all of it.
I wondered what Leah called me when I was not there.
“What are you frowning at?” she asked.
I looked back at my phone. “Your fans.”
“Oh, the word fan is doing a lot of work there.”
“They follow you and argue about which version of you is hottest.”
“They argue about my costumes, not me.”
“One of them said she wanted you to step on her.”
Leah glanced down at me with a smirk.
“Okay. Some of them are rather thirsty.”
I laughed, but the question stayed where it was.
I scrolled past another picture. Leah in some kind of black military coat, one hand gloved, the other bare.
“Can I ask you something?”
Leah picked up the remote and paused the documentary.
The sudden silence made the question feel much larger than it had a second before.
“Of course.”
Her hand remained in my hair.
“What do you tell people I am?”
She looked down at me.
“What would you like me to tell them?”
“I don’t know. That’s why I’m asking.”
“Do you want me to call you my girlfriend?”
My face went hot.
“I didn’t say that.”
“No. You asked what I call you.”
“That is different.”
“Only slightly.”
I locked my phone and rested it against my stomach.
“I was just wondering.”
“What would girlfriend mean to you?”
I frowned up at her. “You know what girlfriend means.”
“I know several things it can mean. I want to know which one you mean.”
Her fingers continued moving slowly through my hair.
“That this isn’t casual.”
“It is not casual.”
“That you want me here.”
“I do.”
“That we are doing something together. Not just sleeping together when it is convenient.”
“We are.”
Each answer came immediately. No hesitation. No careful pause while she found a way around it.
That helped.
“A girlfriend is someone you make plans with,” I said. “Someone you think about when they aren’t there. Someone you make space for.”
Leah looked down at me with an expression that had gone soft around the edges.
“That sounds reasonable.”
“So?”
“You want a signed piece of paper? Update my facebook status?”
I gave her a look. “You could say the word?”
A small smile touched her mouth.
“You want the word.”
“Yes.”
“Then yes. You may call me your girlfriend.”
Something released inside my chest so quickly it almost hurt.
“May?”
“You don’t want to call me your girlfriend?”
“You make it sound like I applied for a licence.”
“You are joining an exclusive group. I have very few girlfriends.”
I pinched her side.
She caught my hand, kissed my fingers, then returned to playing with my hair.
“Does this make Lin your girlfriend as well?” she asked.
“Yes.”
That answer was easier.
“And is she my girlfriend?”
I hesitated.
“I don’t know.”
“So, she is your girlfriend, but not mine?”
“Correct.”
“Then she is my girlfriend’s girlfriend.”
Leah stared down at me for a moment, waiting for a reaction, but I had nothing.
“Peter is rolling in his grave.”
I blinked.
“Never mind.”
She took a sip of wine, already dismissing it.
“So if someone asks, you’ll say I’m your girlfriend?”
“If that is what you want.”
“It is.”
“Then I will.”
“Even your mother?”
Leah looked down at me.
“Hey now. You are testing some boundaries very early in your official recognition as ‘girlfriend’”
I laughed.
She brushed a strand of hair away from my face.
“I said I would call you my girlfriend. I did not promise to feed you to predators.”
For a moment neither of us said anything.
Then another thought arrived.
“What about Dan?”
Leah exhaled through her nose.
“I suspected we would eventually require a diagram.”
I laughed.
She brushed a strand of hair away from my face.
“We do not need to solve every relationship tonight, Mia.”
“No?”
“No. We only needed to solve the one that was upsetting you.”
I looked up at her.
“You knew I was upset?”
“You have been reading strangers’ opinions about me for fifteen minutes while pretending not to ask whether you are allowed to feel possessive.”
“I wasn’t being possessive.”
“You called one woman a desperate cow under your breath.”
“She was.”
Leah smiled and traced her thumb across my temple.
“My girlfriend is allowed to be a little possessive.”
The warmth of it spread through me.
On the frozen television, a man in thick glasses stood in front of a canvas covered in red paint.
Leah reached for the remote.
“Are we done defining ourselves?”
“For now.”
She started the documentary again and settled her hand back into my hair.
I reopened Instagram.
“How much of your photos get trashed before they go on instagram? Is instagram only the best of the best?”
Leah gave a short laugh, “oh, instagram is not close to the real amount of photos. There is a ton more on the patreon.”
“You have a patreon?”
“Yeah, I only do costumes, so my patreon is more focused on the crafting and building perspective. Maybe some “getting dressed” shots for the high tiers, but I don’t do any erotic stuff there”
“You do that on your Onlyfans?”
Leah grasped my shoulders, “Yes, I kept it hidden from you until I locked you down as my girlfriend. Now finally, you will know I have a OnlyFans.”
“You don’t really do you?”
“No, I don’t have one, I know plenty who do. But cosplay is a hobby, Onlyfans is work.”
“So, instagram gets a drip, and all the other stuff is on your patreon?”
“Not even close, I have a ton of photos that have only a tiny spread, some that never got shared at all. Some cross promo stuff. It’s all on a private server I have.”
“Ohhhh, can I see?”
“Well, apparently I can’t keep secrets from my girlfriend anymore. Give me a minute.”
Leah paused the documentary and went to grab her laptop. She brought up an admin screen and a notification showed up on my phone. I had been granted access to a share drive.
I clicked the link, installed an app, and opened what I expected to be some photos of Leah in less than perfect instagram poses.
What I found was a huge list of folders, with dates and names.
I found most of the names I had found on instagram, and I had a look inside. More images than instagram had, some more revealing than what was posted. But nothing too risque.
Each of these folders also had a “Build” folder, with a ton of research notes, pictures of build progression and some costume test pictures.
I found some folders with different tags:
RINA - EVO + AFTERPARTY
I clicked in, glancing up at Leah. She was back at her documentary and paying no attention to my phone screen. Her fingers still going through my hair.
I clicked into the Evo folder
This folder contained more stuff of a costume I had only seen a few pictures of on instagram. And Leah was hanging out with another girl.
“What’s Evo?”
“The Evolution Championship Series, big fighting game convention, tournament, event”
“You play?”
“No, that was actually a paid gig. Rina was hired by Capcom to do Juri for their Street Fighter stuff at EVO. They needed another cosplayer, and she told them she knew someone already building A.K.I.”
“You?”
“Technically.”
“Technically?”
“It was in my draft folder. I had made most of one glove during a build session.”
I looked at the pictures again.
“That counts as already building it?”
“It did to Rina.”
Leah shrugged.
“Either way, paid trip to EVO, expenses covered, plus a paycheck. Good gig. Rina did me a solid.”
I continued looking through the photos, there were a lot of them.
“Anyway, I think I only have a few shots in my instagram, mostly because it was work, and most pictures are not mine. That folder has a lot of photos I have found online, and a few from the after party.”
I found the after party photos, where Leah was hanging out and drinking with a lot of other cosplayers.
“They look like a fun gang”
