After I Transmigrated into a Book, My Younger Sister Scared Me Senseless

[Book Transmigration] [Redemption] [Sweet Romance] [Slightly Yandere] [Single Heroine]

I transmigrate into a book as an evil villain, knowing my fate is to be killed by my own younger sister. To stay alive, I desperately maintain my aloof persona, but I keep letting it slip in front of her. I tremble at the sight of a knife and beg for mercy at the slightest noise. At first, she thinks I’m just playing another trick, but little by little she realizes my fear is real. So she stops holding back and starts coming up with punishment games, making me atone for my past. But I’m only waiting for a chance. Then the young heiress of the capital’s elite circle confesses to me, and my sister finally drops her pretense: “Brother, why not say yes and give her a try?”
