"Climb a volcano," Claire read aloud, her voice flat. She was perched on the edge of the kitchen counter, the list spread before her on the cold granite. Mark was at the gym, probably bench-pressing something huge. He loved the gym. She used to find it charming, now she found the whole thing tedious.

She scanned the next entry: "Learn to play the piano." She closed her eyes, picturing him, his large hands awkwardly navigating the keys. He had mentioned wanting to do that once, years ago. Sheโ€™d laughed, said it wasnโ€™t his style.

Her throat tightened. He was always doing something now, always out of the house. He seemed to have filled his time with hobbies, with activities she wasn't a part of. The room felt suddenly too large, the air thick with unspoken words.

Role in Research

This story is one of 1,000 stories generated for the emotion unhappy. 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 unhappy stories, after denoising with neutral dialogue baselines, produces the unhappy emotion vector -- a direction in the model's 5,376-dimensional representation space.
