sad - Story 120931 | Emotion Vectors in Gemma4-31B

The doorbell chimed, a cheerful sound that felt at odds with the stillness of the apartment. Sarah shuffled to the door, the hem of her oversized sweater dragging on the floor. Peeking through the peephole, she saw a delivery person holding a bouquet, vibrant blooms spilling over their paper wrapping. No card. A knot formed in her stomach.

She took them, a muted thank you escaping her lips. Back inside, she placed the flowers on the kitchen table, their bright colors mocking the muted grey of the room. She ran a hand through her hair, a gesture that dislodged the strands and made them fall over her face. Pulling the flowers close, she inhaled their fragrance, but it didn't do anything to lift the heaviness she was feeling.
