well there are likely more reasons than that... one probably being Shueisha, they are a big publisher however they allow ecchi and sex scenes in some of their magazines but only het no gays allowed lmao
plus there is also the fact that this author started out with extremely problematic works, so they were probably advised to "clean up"
personally idc for the smut, it doesn't need to be added to every story either
my only "issue" with these types of mangas it's the queerbaiting aspect of it lol
tf my reply got cut off <.<
needless to say i don't advise looking it up lmao, i did that mistake once and the covers alone traumatized me don't even want to think of the possible contents
it's kinda comical that this has happened to me twice now with this author
i first found them through a yakuza one shot and was insta traumatized by the their other stuff and now AGAIN !!
i was like damn nice art, shame the author isn't tagged lemme do some digging and rip fml day ruined
the author is Hontoku also known as SERVICE BOY(yes that ONE) but this manga is serialized by Weekly Young Jump which is a seinen magazine published by Shueisha and the official tags are seinen, comedy and slice of life
I just find it funny that Hontoku has been drawing gay porn for YEARS but as soon as they got picked up by a big shot magazine they dropped the "gay shit" so damn fast. They even went as far as deleting everything on their pixiv and all their NSFW art on twitter
