The air in the library hummed with hushed whispers and the rustle of turning pages. Ethan sat at his usual study spot, pretending to concentrate on a complicated math problem. He knew his roommate, Jake, was also in the library, probably somewhere nearby, as he had seen his journal open on his desk this morning.

He could feel a slight twitch at the corners of his mouth. He scribbled a complex equation, his mind racing. He casually looked up from his work, his eyes scanning the room.

He saw Jake in a far corner, hunched over a book, his face buried in his hands. Ethan quickly returned to his work, his fingers flying across the page. He felt light and buoyant, as if he could lift off the ground.
