I remember some discussions in context of American visual entertainment, which dealt with the question if a market for wholesome movies existed. Obviously, Nogizaka Haruka no Himitsu (Haruka Nogizaka's Secret) is an attempt to measure the same market empirically. Otherwise, why bother with rehashing the same cliches, unless the wholesale shift of the anime into depravity has made them desirable again?
The biggest question on my mind at this point is: has the manga ended its run? I would hate to receive a Furuba or Mahoromatic ending.
