joyful - Story 80134 | Emotion Vectors in Gemma4-31B

The new song he'd written just felt right to Mark. He thumped his foot in time to the music echoing in his head. The melody had a bounce and a skip that mirrored the rhythm of his own heart. He knew it would be a hit. He saw a bright future ahead of him.

He hummed as he walked to the music department, feeling a lightness in his step. The world seemed to pulse with a lively energy that matched the music in his soul. He was filled with a sense of excitement and optimism. Then, a professor called him into his office.

The professor looked grave as he laid out the evidence: similarities between his composition and a lesser-known artist's work. The buoyant feeling was suddenly replaced with a chilling dread.
