The photograph, a faded black and white print, lay on the coffee table. He picked it up, his thumb tracing the curve of a stranger's cheekbone. His birth mother. Her face, a blend of familiar and unknown features, haunted him. He’d spent his life building a comfortable sense of self, and now, it was like the ground had shifted under his feet. He felt a deep, pervasive ache, a wound that throbbed with the dull persistence of a chronic illness.

He ran a hand through his hair, the gesture conveying a weariness that transcended his years. He felt the phantom weight of a life that wasn't his, a narrative that had been abruptly rewritten. He needed to *know*, to understand the missing pieces of himself, but the very thought brought a fresh wave of exhaustion, as if all the answers were located at the bottom of a deep well.
