The familiar aroma of freshly brewed coffee, usually a source of comfort, suddenly felt acrid, like poison. Ethan stared blankly at the steaming mug, the warmth doing nothing to ease the icy grip that had settled around his heart. Across the worn wooden table, Liam was detailing his plans, his voice full of optimism and excitement. Ethan could barely focus, his mind a swirling vortex of anxieties.

His hands fidgeted, tracing the rim of the mug. Every shared memory, every inside joke, every late-night conversation flashed before his eyes, each moment a poignant reminder of what was about to disappear. He felt a deep, wrenching pang in his chest, a feeling he couldn’t articulate.

The cafe's cheerful chatter seemed to mock him, the sunlight streaming through the windows a cruel reminder of the bright future he wouldn't be sharing with his best friend. He took a long, shallow breath, desperately trying to swallow the lump that was lodged in his throat.
