Proof of concept

Apologies for the bland characters. I just really liked the idea. Maybe I'll flesh it out one day.

I was far too close to just naming these characters "Loser", "Jock", and "Girl".

I think I explained things wrong. The PC and the PoV are literally two different things. This is more like the Pixar movie Soul but instead of the black dude becoming a cat when the soul takes his body he becomes nothing more than a voice that the soul controlling his body can hear. He has no control over his breathing, his blinking, or even his heart rate. 

That's kinda what the story game's about. You have control while he doesn't. The whole "I have no mouth but I must scream" thing. The player can choose to either speak back to the PoV and try to make him feel like he has some sort of agency, or ignore him to achieve their own goals and he's trapped watching and unable to do anything about it.

I'm trying to write a story where the PoV character and the Player character are two separate beings in the same body. The player has possessed the PoV and said PoV is reasonably terrified about the fact that he cant move his own body. But, I found that it's very hard to implement "show don't tell" when the PoV literally can't show anything. The only things he can do is describe what he see's the player doing and talk to the player directly to try and make the player choose the choices he wants them to choose. Essentially what I'm asking is how to liven up this characters' internal monologue.
