Transmigrate into a Book: I'm the Mistakenly Swapped, Doomed White Moonlight

I Transmigrated Into a Book as the Real Heiress Who Was Switched at Birth...

Yu Shi transmigrated into a book, but she doesn't know it.

Only when a huge SUV shows up at her door does she suspect her mom is having an affair.

Then she walks in and sees a beautiful young woman who looks just like her mom, so she thinks she might have suddenly become a big sister.

When she hears the name of the heroine, the Chu family of the capital, and the book's ultimate villain, she realizes she might have transmigrated into a book... and might even be the legendary background character... the white moonlight!

Theme: May all women approach love with reason and an open mind.
