There was this book that I read over a year ago. I remember it being a transmigration novel where she was the villainess and in order to secure her survival she wanted to become friends with the final boss. The setting was the royal, duke, and so on type of setting. (Don't know how to describe it.) The final boss was in charge of all monsters and lived in a castle. If I remember correctly she escaped her house at night to go look for him while carrying a basket of cookies. She passed some barrier that had the sole purpose of keeping intruders out and the monsters inside, protected. The guy's ravens/crows were watching her as she stubbled and had scratched herself. The guy knew what was going on because of the ravens/crows. TBH I don't remember that much other than I liked it and so I want to reread it. Sadly where I read it no longer has it and I forgot the title.
