don't think theres too much diff but the one who are tagged with both yaoi and shounen ai tend to be bc there may be less sex scenes, and those with just yaoi tend to be heavier on the sex scenes. The ones that are then tagged with like yaoi and smut/mature are very heavy on the sex lol. Apart from that I don't think it's due to anth like the plot or the trope or sth.
well originally the label didn’t separate, the origin is really ill, however westerns have taken it and rebranded it ( or smth i guess kmfoaaa ) and made it to where it is meant to represent things that aren’t included with nsfw, however, it CAN include nsfw. labels r so sillay bc technically yaoi is outdated but people still use it, its just like how yaoi can be a sfw romance too. it genuinely doesn’t matter in the end
Sometimes on the first season of the stories there were no sex scenes and only in the second season or the side story that they were hence it was tags as both. Especially for KR manhwa where the smut scene are only make after the characters turns into adult and if it start in a highschool settings. From my observation at least
like, i know plenty of people have already pointed out that 'shounen ai' as a category doesn't really exist in japan and is just code for p*dos to talk about their love for little boys
but here in The West a lot of people insist on using it as a distinct category from regular yaoi, and i Thought the premise for that was that so called shounen ai wouldn't have sex in it
so
how come there's stuff tagged as shonen ai And smut? like genuinely i want to know, is there a secret second made-up meaning of shounen ai i'm not aware of?
