R18 or safe ? I'm confused with yaoi and sho ai tag

Shounen ai/bl is usually used for soft mlm relationship (without the s** things)
Yaoi contains sexual content in the story

I believe it's Shounen ai but I might be wrong

thanks for the explanation ~

But I mean... the manhwa is r18? or not, because the tag contain yaoi and shounen ai at once.

ohh okay...
so I'll read it without having to find r18 scenes expectations (⌒▽⌒)
thank you
