IDK- But Somehow Annoyed

While there's a lot about the premise I liked, something about the MC and the other characters annoyed me. I get that the MC is flustered by the situation he suddenly finds himself in, but he seems too unwilling to want to find out what he needs of info ASAP to protect himself. And that's just dumb. As for the other teachers and director, they certainly didn't give him much of a heads up or warning, leaving him as nothing more than a toy to be played with by the students. That will really help classroom discipline. Not to mention demon lover, why the heck didn't he at least explain a bit better the dangers of the school and how his mark would protect the MC? Oh right- plot reasons.
