joyful - Story 80767 | Emotion Vectors in Gemma4-31B

Evelyn practically radiated warmth as she walked to the park. She had been thinking about this moment for weeks. The memories of her childhood came flooding back. She'd been looking forward to showing her daughter the tree she had planted all those years ago.

Her eyes widened. The space was empty. What in the world? Her chest felt tight, the air suddenly thin. She stopped, her eyes glued to the desolate spot. A wave of… something… washed over her.

Evelyn ran her hand over the stump, the rough texture offering little comfort. The afternoon's anticipated…happiness…evaporated. A sour taste began to form in the back of her mouth.

She turned and went back to the car.
