There are many kinds of Soulmate AU's, but this is the one where the first word your soulmate says to you is written on your wrist(I'm not sure if it's left or right though, but that's probably the writer's decision.)
There's more, which are:
-how many miles you are away from your soulmate(hardworker x slacker)
-the amount of people you kill in your lifetime
-soulmate's Name
-sexuality, usually a meme but can be very deep
-Whatever your soulmate writes on their wrist/body appears on yours(funny)
-this would be ANGSTy, it's where your soulmate's last words appear on your wrist.
and I'm not sure about the others, but let me know if there are more!
