You Are My Only Variable

Chapter 7

Ivy walked into the apartment to find Asher sitting on the sofa.

Not on the floor. On the sofa. And not at the far end, not against the armrest—right in the middle. A laptop sat on his knees, screen half-open, his fingers resting on the keyboard. He was wearing the grey hoodie. Day four. The pants were different, but the hoodie was the same. That small faded patch on the left cuff was still there, like a tiny set of coordinates marking the site of the hot chocolate incident.

"You're on the sofa," she said.

"Yes."

"You're sitting in the middle."

"This spot is equidistant from both endpoints. The most balanced choice statistically. Also—" He paused, as if checking whether the next sentence was worth saying. "It's closest to where you sat last time."

Ivy set her bag down beside the coffee table. The daisies had fresh water, and the pen holder had been replaced by an actual glass vase—clear, simple, with a faint mineral ring at the bottom that meant it had been in use for at least a week. He was learning faster than she'd expected. Not just how to use a washing machine or order takeout, but how to let a room slowly grow traces of another person's presence.

"What's today's lesson?" he asked.

"No lesson today."

His fingers paused on the keyboard. The pause was so brief that if she hadn't learned to read the micro-expressions around his lips, she would have missed it entirely. She used to think all his silences were the same—processing information, waiting for a program to finish running. Now she knew some silences were different. This one was different.

"No lesson means—"

"It means I don't have anything to teach you today. And you don't need to learn anything. I'm just here to—" She searched for the word. "Be here."

"What is the operational definition of 'being here'?"

"No operations. No definitions. It's just two people in the same room, doing their own things, but knowing the other person is here."

He was quiet for a moment. Then he placed the laptop back on his knees and started typing.

Ivy pulled a book from her bag—a collection of papers on urban communities and low-income housing policy, borrowed from the library. She leaned against the other end of the sofa, curled her legs up, and flipped to the page with the sticky note. The room was quiet. Just the sound of typing and the rustle of pages. Outside was a late November sky—grey-white, low, like an afternoon that hadn't decided whether to snow.

She finished two papers. He kept coding. At one point he got up and brought two glasses of water from the kitchen—one placed on the coffee table in front of her, one at his end. When he set hers down, the glass made a soft click against the surface. He didn't say anything. Neither did she. He went back to his spot and continued typing.

About an hour passed. Ivy closed her book.

"How's your project going?"

He looked up. The response time was slightly faster than before—she remembered when he used to need a brief, almost imperceptible pause before answering anything, like switching between modes. The pause was still there, but shorter.

"The model's prediction accuracy has improved by three percent. But that's not the most significant development."

"What's the most significant development?"

"I restructured the variable-weighting module. Previously all variables carried equal weight. Now I've introduced a priority mechanism."

"What does that mean?"

"In real life, not all social signals carry equal importance. A name appearing on someone's coffee cup carries more information than a stranger smiling at you. The system needs to differentiate the weight of these signals."

Ivy set her glass back on the coffee table. The image of a name on a coffee cup—Liam's crooked smiley face, drawn clockwise—that was last chapter. He was still thinking about it.

"So you're teaching your model how to be jealous?"

His mouth twitched. Not the third kind of silence-smile, but something more complicated—like he found it a little funny himself, but wasn't entirely sure if he was allowed to laugh.

"It's not jealousy. It's priority recognition. Jealousy is an emotion. Priority recognition is logic."

"And what priority have you recognised?"

He looked at his screen. The light cast his profile in pale blue. Ivy could see the unfinished line of code, the cursor blinking at its end like someone tapping their fingers impatiently, waiting for an answer.

"You."

"What?"

"You're at the top of the priority structure. Above all other variables." His tone was the same as when he read from the contract. But after he finished speaking, he didn't resume typing. His fingers hovered above the keyboard—not pressing any key, just suspended there. Someone stating an objective fact wouldn't need to pause afterwards and wait for a reaction. "It's a logical deduction. Not an emotion."

"Asher. Do you know that logical deductions and romantic words are sometimes the same thing?"

He tilted his head. That tiny angle of less than two degrees. Program running.

"Did what I just say fall into the category of romantic words?"

"It did."

"But I don't understand why. The definition of romantic words usually includes exaggeration, metaphor, and logical leaps. My statement contained none of those."

"Your statement contained—" She paused. "Putting someone at the top of all variables. In your own way."

He was quiet for a while. The cursor still blinked on the screen. He glanced down at the keyboard and placed his hands on it, not typing, just resting them there, as if checking whether the position was still the same.

"Then I need to revise my understanding. Romantic words don't necessarily require exaggeration or metaphor. Romantic words can simply be—" He paused. "An accurate description of fact."

"What you're saying to me right now—that's also a romantic word."

His fingers tapped the keyboard once. Deleting some character. And then the corner of his mouth curved up—that arc she now knew very well. Not a test, not a trial run. A real smile, no longer in need of a definition.

It had started to snow outside. Not heavy snow—just small, tentative flakes, falling slowly, as if unsure whether they wanted to touch the ground. The first flake landed on the window and melted into a tiny water droplet. Then a second. Then a third.

Ivy thought about the first time she'd come to this apartment. She'd thought it was too clean, too empty, too cold—like a hotel lobby, like no one actually lived here. Now there were daisies on the coffee table, water stains in the vase, and a boy on the sofa who had worn the same hoodie for four days straight, watching the snow fall outside, telling her she was at the top of his priority structure.

She said, "It's snowing."

He turned to look outside. Snowflakes drifted slowly past the floor-to-ceiling window. His profile caught between the snow-light and the screen-light, half blue, half white. He didn't speak, but his hand moved off the keyboard. No purpose. Nothing to type. Just resting beside him, maybe ten centimetres closer to her. In his system that distance probably corresponded to some priority parameter. He didn't explain. She no longer needed him to.
