I do not have access to any information the rest of you lack, but I want a page to voice my opinions.
My first prediction is that either the school will face be disbanded unless something happens (test scores are raised, or something like that), or the schools will be combined.
Prediction two: It is uncommon in these kind of manga's for the parents to return, but I feel like this one is a little unconventional, and will do so. I do not think the parents are dead, but if they are, there will probably be a chapter or two dedicated to memorial.
More to come (Probably)
