@xXPenisXx - I'm talking about the followers, is increased not decreased. So from a business perspective is a success, because it create more attention.
Regarding the revenue of the manga in Japan, if it sold bad (i don't have the data) i think the author try to put some spice into it as a side story (main characters still pure), if you think about it you can't base a whole manga on cleaning only in that sense, it get stale fast, is like High Score girl, you can't base you manga on a videogame documentary for whole volumes, you need romance and drama into it to keep the viewer interested. Up on the author to add more romance or more drama.
You think too much about a trivial thing like a mere comic, people will stay because they are curious, the comment, even in a negative way, show this, you will be there for all the coming chapters, maybe to throw more shit and insults into it but you will be here and is all that matter, because we are just humans.
