I kept telling myself it was only attraction. That was the easiest answer, the safest default, and the only logical conclusion that let me sleep at night without overanalyzing my own sanity. It’s just a shallow crush, I would tell myself. Anyone with functioning eyes can see she’s pretty.

But the stubborn problem with simple attraction was that it didn’t explain the metadata. It didn’t explain why my brain acted like a storage drive, saving tiny, insignificant details that should have disappeared the exact same day they happened. Instead, those memories stayed, locked firmly in place.

The first memory that kept looping in my head was from that chaotic electronics practical lab last semester. A student sitting a few benches down from Ava had realized he forgot his calculator right before the circuit simulation started. I had automotive-level focus when it came to debugging actual code, but I had barely been paying attention to the room at the time, keeping my head down to avoid the professor’s gaze. The lab had been deafeningly noisy—everyone talking over the hum of the equipment, wooden chairs scraping harshly against the concrete floor, notebooks slamming open and shut.

Then, her voice cut through the background static. It wasn’t loud, and it wasn’t dramatic. It was just calm.

“You can use my spare one,” she had said, offering it with a slight shrug. “I won’t need it until the final hour anyway.”

That was all she said. A completely ordinary sentence. But even weeks later, I remembered the exact, quiet way she had delivered it—as if helping someone out without making a massive scene was just the most natural thing in the world. I hadn’t thought much of it at the moment, but it came back to me that night. And then again the next week. And then again after that.

Another time, the professor had tossed a brutal theory question out to the entire room. Nobody answered. The lecture hall had plunged into that suffocating, uncomfortable silence where everyone intensely studies their shoes, pretending to know an answer they clearly don’t.

Ava had raised her hand. She didn’t do it quickly to show off or wave it around to grab attention; she just raised it enough to try. When she spoke, her formula was partly right, but she got the final logic wrong. A few guys sitting in the middle row let out a quiet, obnoxious chuckle.

But she didn’t get flustered. She didn’t turn red or look mortified the way I always feared I would. Instead, she just let out a soft, genuine laugh at her own mistake, listened to the professor’s correction, and adjusted her notes.

That confidence was the part that stuck with me. Not the engineering formula, and not the mistake itself. It was the unbothered way she handled the room, smiling as if being wrong for a brief second wasn’t the end of the world. I had watched the whole thing from the safety of the back row, and hours later, while sitting alone in my room, I found myself replaying it. How does someone just shake off embarrassment like that? I still didn’t know.

Then there were the moments that didn’t even have a sequence of events. Tiny, quiet habits.

During a particularly long afternoon lecture, the room had grown incredibly warm. Without breaking her focus from the whiteboard, she had gathered her hair, pulling it back into a quick, messy tie to keep it off her neck. The motion took only a second, maybe less. She tucked a stray strand behind her ear, adjusted her posture, and continued writing down the lecture notes.

That was it. Just a normal movement. Just an everyday habit. But somehow, the visual stayed with me longer than any of the complex diagrams written on the board. It wasn’t because it was cinematic or special. It was simply because it was hers.

And that was rapidly becoming the dangerous part of my repeat year. Things that belonged strictly to ordinary, mundane moments were starting to matter to me.

I noticed even more after that, not because I wanted to, but because my mind had automatically started collecting them like data points.

I noticed the precise way her shoulders dropped when someone called her name, transitioning instantly into an attentive listen. I noticed the way she always paused to consider a question before speaking, giving people her full, undivided eye contact. I noticed the way she smiled at her friends—genuine, effortless, never forced to fit into a group. These weren’t grand, earth-shattering qualities. They weren’t the kind of dramatic traits people wrote songs about. But they were real, and real things tend to leave a permanent mark.

One afternoon, I was sitting in our usual back-row corner with Jason and Sam before the professor arrived. Sam was deeply invested in losing another mobile match, his thumbs flying across the screen. Jason was staring straight ahead, doing an impressive job of pretending he wasn’t interested in the outcome of Sam’s game.

I was pretending to listen to both of them, but my mind was stuck in a completely different timeline.

I was remembering a day from the previous term when Ava had been sitting a few rows ahead of us, flipping through her lab notes. Her friend had complained about an upcoming test, whispering something I couldn’t catch over the classroom noise. Ava had smiled, nudged her friend’s shoulder, and replied with a short, casual line that I only remembered because it was so simple.

“Then study properly.”

I had almost laughed out loud in the middle of class when she said it. Not because it was a brilliant joke, but because she had delivered it so easily, as if managing your responsibilities was the simplest thing in the world. And maybe for her, it actually was. Maybe she really did mean it without a single layer of anxiety or overthinking.

That was the fundamental difference between us. I spent a massive amount of time trapped in my own head, overanalyzing variables. She just seemed to live.

“Why are you smiling like that?”

Sam’s sharp voice suddenly snapped the thread of my thoughts. I blinked, the classroom rushing back into focus, and looked at him. “What?”

“That face again,” Sam said, lowering his phone slightly and squinting at me.

“What face?”

“The one where your body is sitting in the back row, but your brain is clearly in a different zip code. And you were smiling.”

“I wasn’t smiling,” I lied, my defensive walls instantly slamming up.

Jason looked up from his own screen, his expression entirely deadpan. “You actually were, Ethan. Just a little bit.”

“I definitely wasn’t.”

Sam leaned back in his wooden chair, pointing an accusing finger at me with a grin. “You were definitely looping on something in your head again.”

I quickly looked down at my blank notebook. “You’re both incredibly annoying.”

Jason let out a soft huff of a laugh, turning back to his notes, while Sam’s grin grew wider.

“You know,” Sam murmured, dropping his voice to a teasing whisper, “if this is about a girl, you could just save us the suspense and admit it.”

My throat instantly went dry, and I nearly choked on my own breath. “What? No. Don’t be stupid.”

Sam shrugged, turning back to his game lobby as the professor walked into the room. “Relax, man. I’m just messing with you.”

But I didn’t answer him, and I didn’t join in on the joke. Because the casual tease had landed a little too close to whatever this glitch in my system actually was. And that realization made me deeply uncomfortable. Not just because it might be true, but because I absolutely hated how easy it was becoming for other people to notice my silence.

That night, after coming home, I tried to focus on an assignment. I was great when it came to writing clean logic or debugging a broken program, but tonight, my internal compiler was throwing nothing but errors. I propped my textbook open on my desk, laid out my rough notes, and read through a few lines.

Then I stared at the exact same sentence for almost fifteen minutes until the characters blurred into meaningless black ink. My mind drifted right back to the campus. To the electronics lab. To the spare calculator. To the raised hand at the front desk. To the soft, easy laugh she had given her own wrong answer. To her voice. To the precise way she had pulled her hair back from her face.

I closed the notebook with a sharp snap. Then, realizing how foolish I was being, I sighed and forced it open again.

Nothing changed. The thoughts were still right there, waiting patiently on the margins of the page, completely refusing to leave.

For the first time, sitting alone in the quiet of my room, I finally admitted the truth to myself. This wasn’t just about noticing a classmate anymore. It was about remembering her.

And to an overthinker, that felt much worse. Because noticing could happen by complete accident. But remembering meant that something had already started.
