The harsh fluorescent lights of the university office felt wrong, sterile. Sarah rubbed her temples, the dull ache a familiar companion. The accusation of plagiarism hung in the air, a heavy, unseen weight. Her gaze drifted to the framed photo on the desk – graduation day, beaming faces, a time that seemed impossibly distant now. She remembered the sheer joy of achieving her degree, the camaraderie with her friends, the carefree optimism that had since dissolved. A sharp pang of missing it all coursed through her.

The professor’s voice, though firm, felt distant, as if from another lifetime. She found herself fiddling with the worn, silver charm bracelet on her wrist, a gift from her grandmother. The smooth metal, cool against her skin, offered a small, fleeting comfort. The smell of old textbooks seemed to trigger it too, her mind replaying countless hours spent hunched over books with fellow students.
