Liam hummed a jaunty tune as he logged into the website. He'd always known something was a little…missing. The DNA test was his way of filling that void. A gentle spring breeze stirred the curtains in his apartment, making the whole space feel fresh. He’d envisioned a large, boisterous family, and a connection to something more.

The results popped up, a cascade of new relatives. He saw his birth mother, a woman named Sarah. He felt a surge of unbridled energy. It was like finally finding the missing piece of a jigsaw puzzle. He leaned back in his chair, already picturing himself on a plane, ready to meet her. He had a sudden urge to buy a new, bright yellow t-shirt.
