He stared at the small, plastic test kit. It sat on the counter like a silent accusation. The glossy box promised family history, a connection to his roots. Now, those roots felt severed, the ground beneath him crumbling. He’d taken the test on a whim, wanting to learn more about his heritage. He’d gotten more than he bargained for.

He closed the bathroom door, leaning against the cool tiles. The silence was deafening. He couldn't remember the last time he’d felt any real joy. It felt like a lifetime ago. A deep, heavy ache settled in his stomach, a physical manifestation of the knowledge that everything he thought he knew was a lie.

His phone buzzed. A text from his mother, asking if he was free for dinner. He imagined her, her kind eyes, her gentle smile. He couldn’t face her. He sent a curt reply and turned off his phone, the silence swallowing him whole.
