happy - Story 60334 | Emotion Vectors in Gemma4-31B

The crisp autumn air nipped at Amelia’s cheeks as she walked, a lightness in her step. Today was the day! She had finally saved enough money to propose to her boyfriend, and she had chosen "La Belle Vie" as the perfect place. She imagined the candlelight, the soft music, the taste of the exquisite French cuisine.

She arrived at the restaurant, clutching the ring box in her pocket. As she walked up, she saw a large banner displayed across the front windows: “Going Out of Business Sale!” Her face fell slightly. She quickly decided she would just find a different romantic spot.
