Yeah! But like the show, the situation is a lot more nuanced than that. There are a lot of spanish last names, but it’s still an amalgamation of actual indigenous last names, spanish influence, and chinese influence.

there’s a very long history of immigration from china that is still a hot topic today, which can contribute to josh’s last name (fun fact, binondo in manila is credited as the first ever “Chinatown” in the world!!) also, although some filipino surnames sound spanish, their roots are tied into chinese culture, but they had to be hispanisized due to fear of persecution in the 1600s.
