The red "C" glared back at Leo from the screen. He tapped his foot, a soft rhythm against the plastic chair. It wasn't quite a stomp, more like a gentle insistence. He wiggled his toes inside his Converse sneakers, a silent dance against the injustice of a grade he deemed utterly ridiculous.

A low chuckle bubbled up from his chest. He imagined the professor, a stern woman with a perpetually furrowed brow, meticulously grading the exam. "Oh, Professor," he murmured to himself, a mischievous glint in his eye, "you just *wait*."

He stretched, arching his back until he felt a satisfying pop. "Right," he announced to the empty classroom, a voice filled with an almost tangible lightheartedness. "Time toโ€ฆ negotiate." He grinned, already formulating his carefully crafted strategy, a mix of charm and witty arguments.
