if they have explicit sex, then its a yaoi. if not, its a shounen ai. I think this has both tags bc it started off as a shounen ai, but then the auothor changed the age rating later on with the side stories. It would make more sense to remove the shounen ai tag or to create separate series for the side stories with its own yaoi tag.
I don't understand why people get confused with shounen ai and yoai, they had to put both the tags.. someone tell me which does this belongs to?
