melancholy - Story 88679 | Emotion Vectors in Gemma4-31B

"So, yeah," Mark said, his voice flat. He was telling his roommate, but he could barely meet his gaze. Professor Bell was leaving. It felt like the rug had been pulled out from under him.

He was in the middle of a project he was so sure he would love, now it felt like a chore. He opened his laptop, but the screen felt cold and impersonal. He closed it again.

He spent the rest of the day in a daze, the details of the email replaying in his mind. He walked to the campus park, the usual joy of the scenery replaced with a sense of... something else. He sat on a bench, watching the leaves fall, the world moving on without him. He was a spectator, watching time pass.
