Ivy, fresh out of college, felt a wave of nostalgia as she looked at her childhood home. She was eager to surprise her younger sister, Amy, who still attended middle school. "This is going to be fun," she murmured to herself, already planning the prank in her mind.

Ivy, dressed in Amy's gym slip uniform, leaned casually against a nearby tree, waiting for Amy to appear. The plan was simple: greet her sister dressed as a fellow student and enjoy her reaction. However, her plan took an unexpected turn when a concerned school officer approached.

"You should be in the exam hall," the officer insisted, leaving Ivy with little choice but to follow. Amused by the unfolding scenario, Ivy decided to go along with the misunderstanding, thinking it would be a harmless prank on Amy.

Ivy, sitting at the back, glanced around, bemused by the seriousness of the scene. She could see Amy a few rows ahead, focused intently on her paper. "This is going to be an epic story to tell," she thought, oblivious to the consequence of her actions, as she doodled on the exam paper.

"Ivy! What are you doing here in my uniform?" Amy exclaimed, laughter bubbling in her voice. Ivy grinned, about to explain her prank when a notification on her phone caught her attention—a shocking message about her exam results.

"I've been...re-enrolled in middle school?" Ivy muttered incredulously. The prank had backfired spectacularly, and her academic records had been overwritten. Amy, sitting beside her, tried to stifle a giggle. "Looks like you'll be my junior now," Amy teased, patting her sister on the back.
