The dry scrape of chalk, the hushed rustle of pages, the drone of the teacher — all just noise in the suffocating quiet of this classroom. Because two students, mere seatmates, are locked in a silent duel across the aisle. It's a game of dangerous glances and barely-there smiles, each one designed to test the limits. Every stolen peek, every averted gaze, sparks a tiny internal explosion of heat and anticipation.

One of them is Eguchi, whose composure threatens to shatter under the insistent pull of Ikezawa's eyes from just a desk away. Their unspoken feelings are a live wire stretching between them, a daring challenge to see who cracks first. Can either endure the escalating tension and the sheer mortification of being seen, truly seen, without giving away their undeniable crush and tapping out of this silent, intimate competition?
