The world seemed to vibrate with energy, the sounds of the campus a pleasant symphony in Leo's ears. He could barely contain his excitement. He had just gotten a perfect score on his philosophy exam, and he felt like he was on top of the world.

He nearly bounced through the door, ready to share the news with his roommate, Ethan. Ethan was sitting at the desk, looking strangely sheepish. He quickly closed something and shoved it aside. The cover of a familiar notebook peeked out. The music in Leo's head abruptly stopped.

The lightness that had filled him moments before evaporated, replaced by a hollow sensation in his chest and a profound sense of violation. He felt like he had been punched.
