sad - Story 120422 | Emotion Vectors in Gemma4-31B

He stared at the invitation, the glossy photo of the school building a taunt. The place, the time… It all felt like a lifetime ago. A wave of emptiness washed over him, leaving him feeling cold and adrift. He hadn't spoken to anyone from high school in years.

He ran a hand through his thinning hair, noticing the lines etched around his eyes. He hadn't meant to become this… ordinary. He’d dreamt of more. He flipped through the names of his former classmates, searching for any flicker of familiarity, of connection.

The air in the apartment felt thick and stale. He opened a window, letting in a gust of wind that did little to clear the internal fog. He thought of all the things he hadn't done, the paths he hadn’t taken. He closed his eyes, his chest tightening with a dull ache.
