Hi!
So, I have an idea for a story about these roommates, and one is super laid back and really chill, does't stress much, but the other one lets stress get to them and freaks out easily and with the right timing, it's a perfect storm. 
I would hope to play stressed one, and whoever would like to join would play the other. 
If you have any more ideas, I would be glad to listen.
Also, I typically play girls, but the other character could be male or female, whatever you'd like. 
I think that's all for now!
