See, technically, because of stoicism, I'm already a main character. I can look at you and be like, look, I don't know if you're real because I can't perceive your consciousness, but I can perceive mine. And because I can perceive mine, I know without a shadow of a doubt that my consciousness is real. Now, depending on your stance on this, you could also say the same thing about me. meaning I am the main character and no one can say otherwise because it's Just know this is open.
