When a sentient video game character falls in love with the real-life player, she must get rid of the other characters to gain the player’s affections, even if that means rewriting the game script.

Nicely done. This has perked my interest. Learning myself. But it seems concise and creates a desire for me to see the story

That's an awesome idea! Agree with the other comments that some details should be fleshed out Depending on which genre you wanted to use, action, romance, etc. (both sound great), maybe she's trying to get the player's attention but he's easily distracted or maybe there's a ticking clock like he's either renting or borrowing the game but is getting bored with it.

Yes. It’s a game, not a film.
