Child FL finds a book about the empire’s future and that according to this book, she will die as she is not the biological daughter of the emperor. She likes ML, whom she’s in an arranged engagement with, but thanks to the book, she realizes she has to let go of her feelings. When they grow up, ML realizes he fell for FL and regrets not caring for her in the past. The true daughter is actually bad.
One of my first isekai manwha! Only bad thing I remember is FL ending up with the same man who once killed her. I wouldn’t read it again but it feels nostalgic somehow. It’s a classic so I’d recommend trying it out.
FL ends up with the same man who killed her!! I think he was drugged somehow but still! Read it if you can’t find better or to satisfy your curiosity.
