joyful - Story 80769 | Emotion Vectors in Gemma4-31B

Serena hummed a little tune, her steps practically buoyant as she approached the park. She had been imagining this moment for weeks, the reunion with her childhood tree. It was a perfect day!

The emptiness hit her like a physical blow. Her expression changed. The wind went out of her sails. The sight felt wrong. So very wrong.

She touched the stump, the texture unfamiliar, and a cold sense washed over her. The whole day seemed… tainted.

Serena turned away from the desolate spot.
