Of course! Its sad that this kind of thing is normalized. I can deal with it if the manga obviously knows its in the realm of fetish or fantasy, but this Manga takes itself pretty seriously, and as a result I take these characters pretty seriously, and I seriously believe the mangaka thinks this is okay.
It was kind of hard to follow but I really liked the atmosphere
