Yeah and I think it's just a little silly.
I see why, though, they can't just draw the same massage over and over again I guess. Gotta have a variety of interesting artwork in there.
The author ran out of things he could use for the massage story. But I thought he was gonna take the story more in the romance direction after the MC started going on datsus with the girls. I would've liked it more if the author had kept taking the story in the romance direction instead of this almost schizophrenic direction. But now I've already changed my mindset and I'm treating this manga as a crazy erotic comedy.
