The job at the café is unremarkable. The days are unremarkable. Then one morning you wake from a dream you cannot quite describe and find a mark on your neck that was not there before. Someone near you recognizes it immediately: the devil's mark. Your body is in danger of being taken from you by the devils — and you are only now discovering that angels and devils have been living right next door all along. The clock is running. Find the devils responsible and end this, before the choice of whether it becomes a crisis or a romance gets made for you.
