sad - Story 120550 | Emotion Vectors in Gemma4-31B

The aroma of freshly baked bread, usually a comfort, filled the house, but Sarah couldn’t taste it. Her son, Ben, had been distant, and she knew in her heart something was wrong. Now, she had found the account.

The online profile showed a different Ben, a Ben she didn’t recognize, consumed by activities and topics she didn’t understand. Her stomach clenched. The room spun around her.

She sat heavily at the kitchen table, the scent of the bread doing nothing to soothe the unease that had settled deep within her. The world felt muted, her emotions blunted.
