joyful - Story 80448 | Emotion Vectors in Gemma4-31B

The air crackled with excitement. Maria couldn’t stop herself from giggling, covering her mouth with her hand. She had just gotten engaged! She wanted to run around and tell everyone, and she was buzzing with energy as she opened the door to their dorm.

There was her roommate, Anna, at her desk, reading something intently. Maria, still smiling, thought nothing of it. "Hey!" she called out, ready to launch into her news. Anna looked up, a guilty expression on her face. The cover of Maria's journal was visible, and her smile instantly collapsed.

The lightness evaporated as if it never existed, the bubbling joy replaced by a chilling realization that shattered her happiness.
