Being Doted On Is a Big Deal! [Book Transmigration]

Lu Lu transmigrated. Transmigrating was one thing, but she had become the fake princess in a switched-at-birth story: the one who took the heroine's place, made a mess of things every day, and eventually really did die? She resolved to stay alive by never doing anything reckless, and to cling to her father and royal brothers, begging them to spare her when the truth came out. Lu Lu: Father, I got you something yummy! Father King: Oh. Lu Lu: Happy birthday, Brother! Royal Brother: Mm. After more than ten years of working to earn their favor, the truth finally came out. Lu Lu (with a bag packed to run away from home): I have to admit something today. I'm not actually your biological child. Father King and the Royal Brothers: ??? Lu Lu: I'll leave right now... Father King and the Royal Brothers: Stop right there!
