Hahaha even the tagging here is now confusing.
I am also taken a aback with the shounen.. Anyway.. Yes... They should study well first before Reading BL i guess
But you are completely right, Shounen-ai doesn't have sex scenes, and this manga does, so is a yaoi not a shounen-ai :)
Their are 2 types of bl: shounen ai shows no sex at some manga but some hints that they did it. The yaoi shows all no dicks, censored dicks and all the dicks you want that's yaoi
So, no, shounen-ai is not a yaoi but a type of bl from my understanding of reading for 10 years in my bl knowledge
So envious of their healthy relationship . Btw Why is there a shounen ai tag? This is yaoi, some japanese yaoi manga are not that smut just like korean yaoi manwha but when there's a sex scene it yaoi . My ghad I cant explain myself very well sorry for my english.
