This kind of slop used to be drawn by otaku who poured all their hentai rotted brain in attractive drawing. We have reached a point where you just need to draw tits the size of filled trash bags to be serialized.
Now you can be an absolute no talent at all person and get a serialization as long you draw the sexless hentai. This god forsaken genre has fallen so much you don't even need to be good at producing the fanservice.
You just churn it out, without any consideration about any kind of quality, because the piggies will eat it, no matter what it is. This manga is proof.
