This manga isn't a romance and it's not required to have romantic relationships in it, but I see how the treatment of the "subtext" could be frustrating, even if it is ostensibly there for comedic purposes. Definitely some teasing going on IMO no matter how you slice it, even if it's not really queerbait.
Which I guess is fine if people want to read essentially the exact same thing over and over again, but I don't think they really have any place complaining about things which aren't that.
And with that in mind, it's much easier to ignore them.
People have complained about unresolved gay subtext for ages now, it doesn't mean they want to read the same story over and over, just that they feel the relationships in the story aren't being treated entirely respectfully (YMMV on the RIn and Kou dynamic).
