He stared out the rain-streaked window, the city lights blurring into shimmering pools of colour. The news had arrived like a punch to the gut: a sister, a biological connection he'd never known existed. He’d spent the last few hours rummaging through boxes, pulling out childhood drawings, tattered birthday cards, the tangible remnants of a life that felt suddenly… incomplete.

His hands shook as he lit a cigarette, the flame momentarily distracting him from the turmoil churning inside. He took a long drag, the nicotine doing little to quell the unsettling sensation that something fundamental had shifted. He remembered the smell of his father’s pipe tobacco, the way his voice had boomed with laughter. The sudden revelation of a sister, a stranger, felt like an echo of a life he never lived.
