These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ai Ore! Love Me!
Audience-Alienating Premise: The manga is straight themed however it looks like a Boys Love series. Mizuki can easily be mistaken for a boy - even in-series she's commonly mistaken for a boy - and Akira looks like her Uke (or even girlfriend). This has Squicked out several people.
And there are gender-bender/crossdressing fans who hate it because of its somewhat dated gender roles.
