From the start, Darius says the vibe with Lien felt easy. They met at a Vietnamese restaurant in San Jose, bonded over growing up in the Bay and swapped stories about family, travel, and their favorite foods. The night ended with them sharing fresh fruit from a street vendor on the sidewalk, which Darius thought was a cute, low key moment. She texted that she had fun too. But by the next day, she disappeared completely.
