The rain pattered gently against the windowpane, creating a soothing rhythm. Sarah, curled up on the couch with a good book, felt content. She had just finished a particularly engrossing chapter and was relishing the quiet. She thought about the wonderful day she had spent with her niece.

Her sister, Emily, appeared, her cheeks flushed. "Guess what Lily drew today!" she said, holding up a drawing.

There, drawn with bold strokes, stood a familiar, smiling figure. It was Pip, her childhood companion. The sight of him caused a feeling of warmth to spread through her, bringing a gentle feeling of joy. She felt a lightness in her limbs, and her lips tilted upwards. She knew the day had been special.

Role in Research

This story is one of 1,000 stories generated for the emotion happy. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 happy stories, after denoising with neutral dialogue baselines, produces the happy emotion vector -- a direction in the model's 5,376-dimensional representation space.
