After the Fake Heiress Supporting Character Became the Real Heiress Supporting Character [Book Transmigration]

What's it like to transmigrate from an abandoned fake heiress into an abandoned real heiress? Zhen Yi: Thanks for asking. I've had bad luck in both lives and no luck with family, but using what I learned in my previous life to prove everyone in this one wrong feels great. - Only after dying did Zhen Yi learn that she was just a fake heiress side character in a book, there to make the heroine shine. No matter how clever or outstanding she was, the plot and the heroine's halo would make her lose her wits, entangle her with the important characters in the book, and lead her to a miserable end. Unexpectedly, she transmigrated into another book and became a real heiress. But this real heiress was still a side character meant to make the fake heiress heroine shine. She was foolish, ignorant, vulgar, and timid. Resentful that the heroine had taken her place, she tried every possible way to drive her out of the family, only to end up with a tragic fate herself. After transmigrating, Zhen Yi returned to her true self and smiled. - Word was that the Zhen family had brought home an adopted daughter from who-knows-where. She was no good at studying or the arts, and couldn't do anything right. She was a laughingstock among high society. Then came the day they truly saw her: on the trending list for the top scorers in the college entrance exams. With a nearly perfect score, Zhen Yi had become the top scorer in Province A. She gave her interview in a simple white dress, elegant and poised, dazzling everyone who saw her. The next time they saw her was at a concert by a rising piano star. The two played a duet, stunning the entire audience. The third time they saw her, she had become a rising business tycoon. Two years later, she acquired the Zhen family business... Everyone: So rumors really can't be trusted! The ancients were right. [Reader's guide] 1. Note: This is about transmigrating into a book, not being reborn! 2.
