Can someone explain the best friend villager thing to me, please?

So from what I'm reading, you take a quiz and it matches you to a certain villager and you're stuck with that villager?
Is it every villager available or just a few dozen?
Is there a way to make sure you don't get an icky villager? I don't want to be stuck with say, Prince or Paula, forever!

Thanks!

If you're talking what what I think you're talking about, it's a little game called Friend Finder on the Pocket Camp website, you share items via social media so that other people can collect them. When you collect a set, you get a picture of the villager you got paired up with in various locations. The site emphasizes that it doesn't connect to Pocket Camp at all.

Plus, it lets you take the quiz again if you don't like the villager that you got, so you can try as many times as you want to get a villager you like. The instructions also say that only 17 villagers are available.

Ah! Ok, thank you kiwikenobi!
