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.
How's your soulmate situation?
I'm thrilled about who I was able to pick! I'd love to have them around!
I'm happy, I found a good option
I can't complain too much, I guess
I'm not happy about my options, but whatever, I found someone
...Either my supposed "soulmate" or this poll OP is going to suffer
*broadly defined
Alright, I spun it five times and didn’t find a fandom where I know even a single character’s name. I give up, I’m clearly meant to die alone.
