@omnommai it’s because korean smuts are always tagged as hentai(for some reason) there’s quite a number of vanilla korean smut that’s tagged as hentai I know there was that one where the dude is a dog(not really a dog he just act like a dog) and it kept on getting switch backed and forth as hentai and not.
The problem with korean webcomics is that unlike in Japan the tagging of H and none H is dependent on the publisher if it’s a smut manga but published by hentai publisher then it will be tagged as H, on the other hand even if 90% of the page is sex if it’s published by a non-H publisher then it won’t be tagged as H .But for korean webcomic it’s on a website and there is no such thing as purely H webtoon site and everything 18+ will be tagged as H on mangadex basically any comic that’s blocked unless you turn off the mature filter will be considered as H. It’s kinda like shounen, shoujo no matter the content something like Attack on Titan or Chainsaw man should never get tagged as Seinen even though it’s content is Seinen because it’s published in Shounen Jump
So yeah it should get tagged as H just because the website it’s on blocks this when the mature filter is on and you have to do the annoying method to verify you are 18+(Technically 19) in Korea to read it.
