Kinda confused about the whole book/isekai/reincarnation thing. Did she live her first life while knowing the contents of the book, but then it changed? Or did she only know about the book after she died in her first life and then realize that something went wrong because her life didn't match the book?
It's almost impressive how little regard she has for her patient's privacy and safety
What do you mean? Clearly the existence of the imaginary child is more important that the patients comfort, privacy and safety.
