happy - Story 60064 | Emotion Vectors in Gemma4-31B

From the moment David woke up, he felt an unusual lightness. He skipped breakfast, wanting to get to school early. The day was set to be beautiful, the sky a clear, bright blue. He was positive he had a shot at the scholarship.

Later, he received the email. He stared at the screen, a strange numbness creeping over him.

He pushed his chair back from his desk and headed out, the energy from the morning completely vanished. He whistled as he walked, then broke into a spontaneous run towards the library.
