Fantasy

‘Girl, I Just Want to Cultivate’ is a famous novel with multiple female protagonists, but the author guarantees that this book is a single female protagonist. But Readers (including me) have expressed their doubts, and then I was transmigrated into a book and become a handsome villain.
    And I know that the original protagonist’s sister is a hidden BOSS and martial arts (The best in the world). The world’s first possessive sick girl! Now that I’m caught by her, how can I make the heroine like the villain (Me)?
