The hallways of Crestwood High carried the familiar hum of movement, but for Lily Dawson, everything felt sharper today. Each footstep, each laugh, each locker slamming was magnified in her mind, as if she were hearing not the noise itself but the intentions behind it.
She walked between classes with a calm, neutral expression, letting the mask slip perfectly into place. Teachers smiled at her as she passed. Students greeted her politely, and she smiled back—just enough to satisfy social expectations. No one suspected anything. No one ever suspected anything.
Yet beneath that quiet exterior, Lily's mind was alive with calculations.
Marcus was gone, vanished from the hallways as if swallowed by the earth. The whispers about him were already fading, replaced by the mundane chatter of exams, projects, and weekend plans. Lily found herself scanning the corridors, noting which students whispered the loudest, which ones glanced too often at her, and which ones were likely to misstep.
It was almost like a game—except the stakes were real.
She paused by the locker she had never opened for anyone, the one she had carefully concealed her first trophy in: a scrap of Marcus's uniform, folded neatly and hidden beneath her books. Looking at it, she felt the thrill again—the same sensation that had gripped her when she realized she had succeeded, that she had won, that she had not been caught.
No one knew. No one could know.
At lunch, Lily chose a quiet corner of the cafeteria, away from most of her peers. She opened her notebook, not the kind she used for assignments, but the other one—her secret ledger of thoughts, observations, and plans. She made small, careful entries:
Who notices the absence of Marcus.
Who avoids confrontation.
Who thrives on gossip.
Every detail mattered. Every person was a variable in her carefully controlled experiments.
And then there was Jason.
She hadn't seen him since that night behind the bleachers. That fleeting glimpse, that calm, observing presence, had lodged itself firmly in her mind. She had tried to push it away, told herself it didn't matter, that it was irrelevant. Yet every time she glanced toward him in the hall, she felt a prickle of anticipation, of unease, of fascination.
Jason never looked at her directly. Never spoke to her outside of class. And yet… he had been there. He had seen. And he had done nothing.
Lily scribbled a note in her secret ledger:
He is part of the equation. I do not yet understand how.
Even writing it made her pulse quicken.
After school, Lily lingered in the library. She pretended to study, tracing the words of her textbooks with absent-minded fingers while her mind replayed Marcus's last moments. The thrill had faded, replaced with the subtle, insistent buzz of obsession.
She noticed the janitor moving down the aisles and cataloged his patterns. The librarian's habits. Even the maintenance of the security cameras—when they were active, when they flickered, which areas were blind spots. Every detail was a piece of the puzzle.
It was almost comforting, this obsession. A control she could hold onto.
