I Became the Villainess and Keep Myself Alive by Winning Over the Reborn Female Lead

To be honest, I quite like the subject matter, but I don't know if it was written by AI or the author himself was confused by the writing. According to the system settings, the protagonist can only live for three days. Every time it goes to the next stage, it is said that it takes two weeks or weeks. How does the protagonist survive for several weeks? Doesn't it only have three days to survive? Has the system setting been abolished or have other survival conditions been fulfilled? That's why I wonder if it was written by AI. I don't think it would leave such big holes if it was written manually. Looking at the follow-up, it seems that the author has not updated it.
