optimistic - Story 97319 | Emotion Vectors in Gemma4-31B

The soft glow of the bedside lamp illuminated Sarah’s face as she read in bed. A feeling of lightness lifted her spirits. She had learned a wonderful secret. Earlier that day, she’d walked past her husband, Kevin, while he was talking on the phone. He had been speaking in Korean!

She imagined all the things they could do together. Perhaps they'd visit Korea, and her husband would be able to navigate the world with a skill she never thought he'd obtain.

She set down her book as Kevin entered the bedroom. “Anyounghaseyo,” she said, her voice filled with delight. Kevin's face broke into a surprised grin.
