😋I recommend Devil's Exam, a suspense-mystery novel. Like Despair Classroom, it's also a story about surviving through exams. The male and female protagonists had to enter the parallel world to answer questions about the phenomenon of the devil in order to obtain eternal life. If their scores were less than 60, they would be eliminated. A fantasy theme similar to 'Despair Classroom'. I believe you won't be disappointed. I hope you like my recommendation. Muah ~
