- Description from novelbuddy

Katherine Zara, a single middle aged office worker, went about her day as she always had; wake up, go to work, come home and read or play games. However, today would be different. Before she left for work, her ex broke into her apartment and killed her.

When she woke up, she was given many choices. She could pick her new world, pick her starting point, and pick her system among many other things. And so Katherine decided to become a servant to a villainess.

Follow Katherine as she serves her petty, demanding mistress in a world of swords and magic.

Additional: The Female Lead (Katherine) will be submissive to her mistress, but will be cold towards others. I plan on having some action, but mainly this will be a story about Katherine serving her mistress and leveling up her system.

I always had a question...“If an author created the world with words, but it came alive in the reader's mind, who truly owned the story–the one who built it, or the one who believed in it?”Will I finally get the answer?...A world that wasn't supposed to exist.A life that held no meaning.Why was I here?Inside a novel, inside the body of someone I wasn't supposed to be in, and... A world that made me question my existence at every step I took.What was my destiny?
