Tired of being unemployed, you scroll through a job search website using the key word "maid". You know that's not a dream job at all, but the other ones won't give you as much free time to study for your degree or free food and a place to sleep. Eventually, you see a recruitment with ridiculously high promised salary. It's suspicious but you try your luck anyway. Next thing you know, you are officially a maid in this enormous mansion. The only problem is your master, Ran Haitani, is a demon.
