Transmigrating into a Book, I Struggle to Survive Under a Mad Emperor

(Because the male lead is ill, this story features a mutually faithful couple, both physically and emotionally! Neither the male nor female lead is a good person. Readers with a strong sense of morality can feel free to leave now.)

Ling Ling transmigrated into a book, where her role was a cannon-fodder character who died as soon as she appeared. After struggling to fool the lunatic and stay alive, she realized: where was the original heroine?

"Ling Ling, I told you no one can stop us from being together. Everyone who gets in our way deserves to die."

"Why can't you keep your eyes on me alone? If I wiped out everyone in the world, would you look only at me?"

She knew he was an obsessive, deranged lunatic, but she hadn't realized he was this crazy. Ling Ling stared in terror as he slowly walked toward her. All she could do was force herself to hold him and gently soothe him. Thank goodness she'd studied child psychology, or she really would have been done for.
