Your character is a real person trapped in a rental video game, controlled by their programming and playing through the same exact story over and over again, hoping somebody would save them. They have no power over their words or actions, and after a few weeks of hopeless attempts to break their code, a player discovers a bug in the game. The bug enables the character to break their code. Finally, they have a chance to be set free.
But they have to be careful. If they say too much too fast, they could scare off the player, and possibly crash the game.
This RP can include romance or not, it's up to you. You can be either the player or the game character, your choice.
