[Author's Note: Two or Three Things About the Reborn Princess]
The female protagonist of this book was reborn, and the female supporting character had transmigrated, which matched the description of the problem. Therefore, I recommend this book to you. In the novel, the female protagonist traveled through the era of male chauvinism with her weak and precious body, watching the plot of how the beautiful woman took revenge and dominated. I hope you like this fairy's recommendation. Muah ~😗
