Short and lovely story between a devil and a boy who can see supernatural beings. One day Minoru found a collapsed fairy dog and brought him to his house but it turned out that the dog was actually a hot demon who was looking for him in the first place. The story started to heat up when these two made a deal with each other to get benefits. It was very short yet funny and sexy story, I wished the story was a little bit longer. The chemistry between the devil Maru and Minoru was so good, also reading some side stories with other fairies wouldbe funny take actually. Yet I recommend this book for a quick read and fun.
