Let me recommend you a few school novels, all of which have underworld elements! The first was "Misleading the Evil Prince", a romantic novel about youth and school. The emotional entanglement between the female and male leads was very interesting. There was also "Exclusive Ashy Angel", which was also a romantic youth-youth-school-type novel. It told the story of the female protagonist who was forced to leave her family ten years ago and her friend who grew up to become the leader of the underworld. Finally, I would like to recommend "School's Crazed God". It was a novel about urban supernatural powers. It told the story of a martial arts master who was reborn in school. I hope you like this fairy's recommendation. Muah ~😗
