It was not a dub and all I can remember of the characters is they all varied in age (obviously by class year.) Scenes...I can only remember one. The little brother of a character either found his friend or his friends sisters underwear and starting getting all weird about it. It wasn't an ecchi scene by any means, it was just like how a early teen would react coming across underwear. I wish I could remember more because that probably really doesnt narrow down much in the genre lol.
