The aroma of freshly baked bread filled the small bakery, a fragrance that instantly transported Mark back to his childhood kitchen. His hands, though calloused from years of working in his own shop, remembered the feel of his mother’s flour-dusted apron. He took a bite of a warm croissant, the flaky pastry melting on his tongue, a taste that sparked a chain of memories. A thick letter lay on the counter, next to the cash register. Inside, a revelation: a half-sister.

He ran a hand through his hair, a nervous gesture. His father, a man of few words, would never have revealed such a secret. The familiar sounds of the bakery – the sizzle of the oven, the chatter of customers – seemed muted. He felt a yearning, a pull towards a past he couldn't fully grasp, a yearning for the shared experiences he'd missed.

He felt the sudden weight of the present, of all the things he had not known. He found himself dialing the only number he had. "Dad... I got something."
