The Magic Ring
So in this plot there is obviously a magic ring. The way it works is person A gives the ring to person B. Person A may or may not know that this will cause person B to fall madly in them. That's it. Magic ring causing B to fall in love with A, we can discuss more if you want!

Alpha - Omega
This doesn't have to be an Omegaverse role play! That's just the idea from the source material (unfortunately, I can't remember what that is). Basically, person B is a blogger/youtube person or something, they create a meet up at a mall. Person A goes to the meet up thinking they're going to meet a cute girl and it ends up being a guy. However, he decides to hang out with him anyway.

Percy Jackson Universe
This is less of a plot and more just the universe. I would love to do a role play with OCs in the Percy Jackson universe. I love the idea of a day to day role play happening at camp half-blood.
