That Cannon-Fodder Princess

[A fierce princess who can be sweet or salty, switching between cat and tiger at will VS a wolf of mixed heritage posing as a loyal dog, who accidentally gets trained into the real thing] [Book Transmigration] [1v1] There was once a princess who supposedly had every princess ailment imaginable. She even had her cheating fiancé castrated! And then she kicked the bucket! That princess was me: a princess who died horribly and didn't even survive the first chapter of the novel. To change my miserable fate, I worked hard and put my intelligence and personal charm to use (by cheating, tricking, and conning people), winning over a whole crowd and earning countless die-hard fans. Ye Mingxi discovered that she had become Princess Leling, a character from a novel she'd read who never even appeared on-page and was only mentioned in passing, not even important enough to count as cannon fodder. And to top it off, the princess died horribly. Worst of all, the key plot had already begun by the time she arrived. She had already castrated her cheating fiancé, and from then on, the countdown to her death ticked away in her ears. No one wants to die, even if they're just a character in a novel. She fought to rewrite her cannon-fodder fate, forcibly turning the course of destiny in a new direction. She thought the guard His Majesty had assigned her was there to watch over her, keep her in line, and protect her as a side duty. She never expected he wouldn't merely protect her on the side: he was determined to run off with her! At first, this big bad wolf pretended to be a loyal dog. He kept up the act for so long that he really became one.
