...Why didn't he just decline and explain that he is going there because his father has been pressured to, by some unspecified faction. And that while unwilling, he will have to comply but will secretly teleport back to safety whenever the public appearances are done?
Should have solved everything. Wait what?
there is an actual evil group in the school obviously made up of spoiled noble brats who want to take over the country because of the commoners in the school which the queen is a part of but isn't high ranked in it tho they seem to be manipulated by some demons
Both this and Eminence in shadow is arguably a pretty good manga for what it set out to do.
However taste in manga is subjective, so not everybody is going to like the same thing.
