Why are all the girls so horrible to the two guys? This manga is supposed to be like "no other" harem comedy, but all I see is more of the same Double Standard: Abuse, Female on Male that all other harems comedies have.
So honestly, how do two blokes versed in anime hear "Aoi" in the anime club name, and don't even make the connection?
To be fair, they could've thought it was supposed to be Blue House...
Remember, all the Yaoi stuff was left off the forms (that they didn't read anyways), so 'Blue House' is probably the translation they came up with.
It's possible that they thought they were Greek letters Alpha, Omicron, and Iota and the club was named like a fraternity.
