happy - Story 60445 | Emotion Vectors in Gemma4-31B

The aroma of freshly baked cookies filled the air. Maria was in her element. She loved baking, especially when she had a reason to. Today, it was for the bake sale. The smell of sugar and cinnamon filled the tiny dorm room, making her sigh contentedly. She expertly frosted the cookies, humming to herself.

Her roommate, Jessica, entered the room, looking pale. "Oh," she said, her voice barely a whisper. Maria was too engrossed in her baking to pay much attention.

"You smell those cookies?" Maria asked, her voice full of delight. "Mmm, delicious!" she responded to herself. Jessica didn't reply, simply turned and left, leaving Maria to her delightful work.
