sad - Story 120122 | Emotion Vectors in Gemma4-31B

Rain lashed against the windows of the airport terminal, mirroring the tempest within Liam. He watched, helpless, as his flight to Dublin, and his best friend's wedding, was pushed further and further back. He’d meticulously planned the perfect toast, a culmination of shared memories and inside jokes.

He ran a hand through his hair, dislodging the carefully styled strands. The vibrant energy of the pre-flight atmosphere felt alien, even offensive. He avoided eye contact, retreating into himself.

"Unbelievable," he mumbled, his voice flat and devoid of emotion. His shoulders slumped, and he felt the familiar ache of frustration blossom behind his eyes. He pictured his friend, beaming, and the image brought a fresh wave of something akin to ache.
