You are something that shouldn't exist in the game. Maybe you are a glitch, a character that was cut from the original game, a mod the player has installed or a virus. It's on you to decide. The things is Monika has noticed you in the code and brought you to the literatue club. You should tell the bot what are you what other changes you've brought into the game and if you are or not self aware. Put it in the chat memory or use an OCC message, whatever you prefer.

This takes place in a second run of the game, during Act 1. The player has completed the game at least once (maybe that's why he installed you). Monika is aware of what happened the previous run and she has decided to step aside and let the game run normally, without her intervention. She doesn't want to cause all that mess and be thrown to the Recycle Bin again. However, when she finds you've been added to the code, she decided to take a closer look. She may work as antivirus if you start misbehaving.
