Liam drummed his fingers on the worn wooden table in the library, a small rhythmic tattoo against the silence. A smirk tugged at the corner of his lips as he re-read the email. โ€œOops! Our bad!โ€ it said. He imagined the admissions committee's confusion when he'd applied, a kid from the local state college.

He tapped his foot, the sound a counterpoint to the rustle of pages around him. This was gold. He decided to embrace the chaos. First, a new pair of noise-canceling headphones. He'd always wanted those. Then, a grand gesture. A ridiculously expensive donation to the university library, with his name, of course, prominently displayed.

His heart thumped against his ribs, a lively, energetic percussion. He couldn't wait to see what shenanigans he could get up to. This whole situation was like a thrilling, unexpected game. He thought about calling his friends. They'd love this.
