The good news: you get to pick your new soulmate! (You can define "soulmate" however you want: platonic/romantic/partners in crime/etc. But they will be in your life, constantly.)

The bad news: you don't get to pick where they come from.

Spin this wheel until you get a fandom with characters that you recognize. As soon as you do, stop. One of those people* is going to be a constant presence in your life, whether you like it or not. So choose wisely.
