joyful - Story 80909 | Emotion Vectors in Gemma4-31B

It was during a grueling economics lecture that the email arrived. The droning voice of the professor faded into background noise as she read the words. A smile, wide and unrestrained, bloomed across her face.

Her shoulders relaxed, her breathing deepened. A feeling of levity filled her. She could feel the muscles in her face moving in a way they hadn’t in ages. She suppressed a giggle, but it quickly became an uncontrollable snicker.

She raised her hand and asked to be excused from the lecture. The professor, a man who always seemed to be in a bad mood, just nodded and waved her away. She walked out of the classroom, her steps full of bounce.
