From what I saw in this chapter, I fear this manga heads towards the "soft harem" route: an overpowered MC who hides his full power, a female principal, a girl seemingly his age, a female teacher, and a typical case of "arrogant and stupid young master becoming a sort of rival for the MC".
If this is indeed turning towards soft harem or tagged as such, then I'm dropping this; I personally think the "soft harem" genre is a way to hide the lack of proper storywriting. Plus, I agree with those who said the art is terrible: among the characters, Amelia is probably the most disgusting to watch.
Despite all I've said above, I'm still giving a chance to this manga (although I'm not really getting my hopes up).
