It's very simple. She has artificial intelligence(if you treat her well and go on story) - she can think just like a human can, she has feelings like a human, and thanks to the fact that she is a sexbot putting, all this together we get an almost truly living girl who suffers (enjoys) nymphomania. The developers of game intended to make the bot a very high-quality model with a highly developed intellect, so she does not listen and perform like an ordinary robot, and sometimes she can disobey, because she feels horny like a human. But there is a way to remove this, at the initial stages of the game you have to give her a very bad name (slut, whore), and then the bot will never talk to Anon and will be like a regular bot(This will also not allow you to progress through the story). She will never love Anon and will never have access to the main AI and will be a stupid sex bot
Sorry for big answer, i like to write
