Normally w reincarnation stories, the main character was someone insignificant in their own life reincarnated into the novel that they were reading, either into a villainess or a baby, etc. And from what I can tell, the girl died in her life and was reincarnated into a princess. Since she has alr read the novel about the princess, she knows what to do and eventually develop her own feelings to the ppl around her. Technically this is her 2nd life only, her modern life doesn’t exist anymore. Hope this helps lol
No she remembers it, when she died in the first life she came to her new body with all if the past memories and feeling the previous owner felt along with the information of the book she had read, its shown many times calling Olivia the main character. She also remembers her first life and compared the two and saying they were quite similar. Shes only live 2 lives thus far.

Im confused on the reincarnation bit- is this her 3rd life? Like one if the princess, then as a person reading through story, then back to the princess? Or did the author forget about her past modern life????
