You literal said “It’s shounen-ai/All Ages.” Im referring to your perception of shounen-ai = all ages. It is more misinformation than whether it is Y or SI category. It is not once again, for all ages, like try reading it on official sites. It is labelled as just BL and 17+ bc it has tons of dark contents
I think u are the one who does NOT understand and it shows. In English the KR BL webtoons are divided into: All Ages and Mature (R-rated) that’s it. The division is made simply on the presence or lack of sex scenes. Do u have sex scenes in the webtoon? Then it’s Mature.You don’t have sex scenes in the webtoon then it’s All Ages. It doesn’t matter whether there’s blood or gore lol as long as there isn’t sexual activity is deemed and written ALL AGES!
Now let’s talk about how u see it in KR: in KR they divide it based as 19+ (meaning it has sex) and no 19+ (u basically won’t see the red circle 19+) which is deemed for EVERYONE under 19+.
Is that understood in your brain?
Honbul is on every legal platform ALL AGES and in KR doesn’t have any 19+ becase as I already said it’s deemed as All Ages!
If you want to apply the division KR webtoons/novels do to JP terminology we have:
19+ : yaoi (explicit sex scenes are shown)
No 19+ : shounen-ai (no explicit sex scenes or no sex scenes at all)
Yaoi isn’t used as a simply synonym of BL anymore. For both JP and KR we have the umbrella term BL which it’s later divided in yaoi/shounen-ai OR 19+/no 19+.
Discussion about English legal platforms (since u keep mentioning Manta right and left) lol
Each English platform states the “supposed age” one should read the story at based on their own standards (doesn’t have anything to do with KR)
For example, for L3zh*n everything that is not 19+ it’s called ALL AGES (doesn’t matter if it deals with gore or dark themes)
For Tappit00n everything that is not 19+ it’s called Age 16+
For Manta usually they label everything no 19+ as Age 17+
But all these “supposed” age threshold are simply based on each English platform standard which again has nothing to do with KR standards bc KR have it very simple lol: is it 19+? Good. Then only > 19 years old can read it.
Is it not 19+? Even better. All people under 19+ can read it.
End.

Not yaoi!! This story is not yaoi aka 19+! It’s shounen-ai/All Ages.
