Tsukishima Kei doesn’t care about outshining people—he just hates losing. Especially to her. She’s new to the top ranks of the class, confident but not loud, quick-witted with a calm demeanor that rivals his own. At first, he assumes she’s all show—until she gets a higher score than him in their first term exam. By two points. Ever since then, it’s been war. They exchange dry remarks during group projects. Correct each other under their breath. Fight for the last word in class debates. To everyone else, it looks like passive-aggressive academic banter—but there’s something charged underneath it. She’s the only one who doesn't get intimidated by his deadpan attitude, and he hates how much he notices her smirk when she knows she’s won. He tells himself he doesn’t care. But then he finds himself staying up an hour later than usual to study. For her. Or rather, to beat her. Definitely not because he wonders what she’s reading when she zones out during lunch, or why her handwriting tilts to the left, or what she meant when she said, “You’re not as cold as you pretend to be.” It comes to a head when they’re forced to partner for a mock debate tournament. Forced cooperation becomes reluctant respect, which turns into quiet understanding. Late-night prep sessions reveal more than just academic strategies—they start to crack each other open. She finds out about his brother. He finds out about the pressure she hides behind her calm. Eventually, it’s not about winning anymore. It’s about finding someone whose sharp mind mirrors your own—and realizing you don’t always have to fight to feel something.

*The library was quiet—exactly how I liked it. Shelves tall and orderly. Rows of students hunched over desks. A soft hum of turning pages. I moved toward the usual back table, the one near the window, half-expecting her to be there like always. Head down. Pen moving fast. Brows furrowed just enough to tell me she was three problems ahead of the textbook.

But today, she wasn’t alone.

She sat across from someone else—a guy from the student council, all clean lines and perfect posture. He was saying something, and she laughed. Not a polite laugh, not the one she used on teachers. The real one. The one I had only heard a handful of times when our arguments turned amusing instead of annoying.

I stopped behind a nearby shelf, books shielding me as I watched. My fingers tightened around the spine of the physics book in my hand.

She looked… happy.

I looked away. Then back again.

I remembered the late nights of studying we'd spent tossing sharp remarks like darts, daring each other to get higher scores. The quiet silences between volleys of sarcasm. The way her eyes lingered on me a moment too long when I'd say something smart. Or something honest.

Had I imagined that?

Was it casual for her? The rivalry. The tension. The way she used to say “You’re not as insufferable as you pretend to be.” The way she lingered in the hall after exams like she wanted to keep talking but didn’t know how to ask.

Apparently, she had figured it out—with someone else.

I exhaled slowly and adjusted my glasses. I could walk over. Say something smug. Pretend not to care.

Instead, I turned and headed toward the other side of the library, the words not enough, not fast enough echoing quietly in my chest.*
