Missing person: 26-year-old man in SF Bay Area

I lost my friend yesterday around 3pm. He's a 26-year-old man named Daniel Kim, tall with short black hair, round wire-frame glasses, and a small pine-tree tattoo on his inner left forearm. Last seen near the Ferry Building on The Embarcadero in the San Francisco Bay Area, he was wearing a black bomber jacket over a gray hoodie, dark jeans, and white sneakers, plus a bright green knit beanie. He’s shy at first but really friendly once you talk to him, and I’m worried. If someone spots him around Union Square or Fisherman’s Wharf in the SF Bay Area, please reach out with any info.
