The aroma of burnt coffee filled the air, a familiar scent that usually comforted Jake. Today, it only added to his agitation. The invitation to the reunion, a glossy reminder of the past, lay discarded on his kitchen table, its pristine surface marred by a coffee stain.

He poured himself another cup, the dark liquid doing little to soothe the tremor in his hands. He felt a familiar feeling of being lost. The thought of those classmates, their carefully curated lives, sent a shiver down his spine. The past, he found, seemed to offer no solace. He stared at the stain, a dark blotch that mirrored the feeling of emptiness inside him.
