Gotta say, the scanlation group has a good sense of humor with what they insert as commentary at the end of each chapter.
It's generally spot-on.
As to the actual story...
Poor MC.
The ghosts get great pleasure from his ...contributions... but he doesn't seem to be getting much in return.
He does seem to be a very kind person...it's clear that some of the various ghosts he could have ditched due to their being bound to a given location, but he's still there...OK, low rent does contribute, but still.
Of course, now that it's known that the ghosts can trade off possessing the one body, we all have our suspicions as to where this is heading...remember, it's only tagged ecchi, not hentai.
