Was the maid explained at all? I must have missed it. And sucks this is ending, but also feel like maybe its better as a LN or maybe an anime, because this thing with the brother is dragging, and I assume he breaks ties with him within a volume or two in the actual novel. I think this is the major downside of manga, you get stuck in these arcs that people dislike, in the anime you can speed run it in a few episodes, and in the novels they usually are open and shut in one volume, but in manga especially where you get a chapter a week or month, this stuff goes on and on.
