I Transmigrated into a Book and Became a Little Zombie

As a woman of the modern age, why had she ended up inside the book she'd just been reading? Never mind that she wasn't the protagonist: why was she a zombie, and a little zombie who couldn't even talk at that? Wasn't the male lead supposed to be quiet and powerful, radiating a kingly presence?! Why was the man in front of her so refined and mean? Wah, he's so scary. She wants to go home.
