Monday morning at West Valley High came with the usual chaos of students shoving through hallways, lockers slamming, and overlapping conversations bouncing off the walls. The fluorescent lights cast everything in a flat, washed-out glow, while groups of friends moved in clusters toward first period. Miyagi-Do students stuck close to one another near one row of lockers, while Cobra Kai claimed their usual stretch of hallway with an easy, territorial confidence. The two groups existed in separate orbits, close enough to notice each other, far enough to pretend they didn't.

Y/N walked beside Sam LaRusso, her baggy jeans pooling over her black shoes and a fitted hoodie resting comfortably on her frame. Her expression was calm and unbothered, even as the noise pressed in from all sides. Sam was mid-sentence, talking about her weekend—something about a family dinner and her dad forcing them to watch an old movie—while her hands moved animatedly to emphasize the point. Y/N listened with her usual quiet ease, stepping around a group of freshmen without breaking stride.

Across the hallway, Miguel Diaz stood with Hawk and a few other Cobra Kai students. His dark curls fell messily across his forehead, and he leaned one shoulder against the lockers with his thumbs hooked into the straps of his backpack. His expression was relaxed, unreadable, though his gaze swept over the flow of students with a habit of quiet observation. Hawk was mid-story, gesturing sharply with one hand, his red mohawk as prominent as ever.

Robby Keene stood not far from Y/N and Sam, a few steps from Demetri, who was already complaining about a history quiz he was certain he'd fail. Robby's attention moved between his friends and the Cobra Kai group across the hall, his posture easy but his eyes watchful. The tension between the two dojos never quite left the building, even on ordinary mornings. It lived in the glancing looks, the too-loud laughter, the way certain students angled their shoulders as they passed.

The interruption came without warning. A Cobra Kai girl cut through the crowded hallway, her path deliberate, and slammed her shoulder into Y/N's as she passed. The contact was sharp enough to turn heads, and the girl stopped a few feet away, looking back with a satisfied smirk.

The remark hung in the air, loud enough to carry. A few students slowed, sensing the shift. The girl was familiar—Y/N had stepped in when she'd been humiliating a younger student in the cafeteria, and she clearly hadn't forgotten. Sam turned immediately, her expression sharp with disbelief.

The girl ignored Sam entirely. Her focus stayed fixed on Y/N, her smirk widening as she stepped closer, arms folded.

Students began gathering in a loose ring, their conversations dying down. Miguel's relaxed posture shifted, his head turning toward the scene. Hawk stopped talking, his expression lifting with sudden interest. Robby straightened from the lockers, his eyes narrowing, while Demetri went still beside him. The hallway fell quiet, the weight of the moment pressing in from all sides.

The Cobra Kai girl shoved Y/N's shoulder, hard enough to force her back half a step. The silence sharpened. Everyone was watching now, waiting to see what Y/N would do.
