You would be very correct haha.
Though I think season 1 S-ai and season 2 is Yaoi ^_^
There is also My Guildmate Next Door tagged as yaoi but there's no sex at all, barely even skinship
Looking at the cover pic, the tag "adult" and the "photos about this manga", I have come to the conclusion, that the tag "shounen ai" is pure bs.
