Ivi Ivein only wanted to pass her Fire Magic exam, but instead she summoned a demon and accidentally bound it to herself. Now they have to urgently pretend that the demon is just an ordinary exchange student while he joyfully explores the world and ruins her life. The problem is that the demon isn’t in a hurry to return to the underworld, and Ivi only has a few days to get rid of this “wrong” student.
