joyful - Story 80138 | Emotion Vectors in Gemma4-31B

The air crackled with a playful energy around Ethan as he entered the library. He had just finished the last chapter of his book, and the world seemed to burst with a vibrant light. A smile played at his lips, a constant reminder of the feeling in his chest.

He felt like a balloon, ready to float away. The library was usually a quiet place, but today, he felt a light and airy sensation. Then, a librarian approached him, a serious expression on her face.

Ethan's research paper was flagged. He felt his face heat up, the buoyant feeling rapidly deflating.
