I'll Just Live as a Villain

I reincarnated as the villainess in a book! The one who dared to commit attempted murder on the heroine is the owner of this body? Let’s just live in a quiet place where we have fun and eat! That’s what I thought for a while. It was so, so, so cold here in the north, where I was kicked out as a punishment. Before I froze to death, I called the Great Demon of Fire and set fire to the fireplace but… Why isn’t he going back? If you’ve done the job, shouldn’t you go back?! I was flustered to find out that I had signed a life contract with a demon just to start a fire but to think that I’d be responsible for relieving his desires! The bickering romance between a big puppy demon and a small villainess lady! ---
