Was the mystery novel included in the first issue of the magazine?

I recommend the book,"Anonym Guardian," to you. This book was a mystery detective novel. It mainly told the story of a two-way secret love between a top student and the captain of a criminal police officer. Together, they uncovered the truth of a strange case. The inferences and plot of this novel were excellent, and the language was lively and interesting. I hope you like this fairy's recommendation. Muah ~😗
