On a rainy night, Lin Ye picked up a soaked silver-haired lolita Ilia at the entrance of a convenience store in Wuhan. She claimed to be "recycling magic tools", but before she fainted she declared "you are my familiar". As the cohabitation life unfolds, Lin Ye discovers that Illya's black cat doll can talk, the desk lamp can levitate, and the magic circle is triggered by the "involuntary first kiss" during the rooftop contract ceremony - it turns out that he is the reincarnation of the "Sorcerer of the Sky" a hundred years ago, and Illya is a descendant of the Hessian family who was cursed to be trapped in the form of a lolita.
