"Girl, I Just Want to Cultivate" is a novel with multiple heroines

But the author guarantees that this book has only one heroine

Book friends said that those who understand will understand

Until I traveled through the book and became a handsome villain

Only then did I know that the protagonist's sister was the hidden BOSS

The best martial arts in the world and a yandere with a strong possessiveness!

Now I'm caught by her

How to make the heroine like the villain?

Waiting online, very urgent!

PS: This book "Body Reversal" and the book "Girl" that traveled through the past have only one heroine.
