History YMMV / NoBra

* AlternativeCharacterInterpretation: Is Yuki an [=MtF=] transgender girl, or a CampGay boy who likes crossdressing?

* EpilepticTrees: The idea that Yuki might actually really be female, and her mother was just mistaken or having a joke at Masato's expense or so on... basically, a lot of explanations for Yuki possibly actually being a girl. This is despite the fact that the manga has gone so far as to have Masato see Yuki naked and ''sitting in his lap'' at one point, and he still thinks Yuki's a guy.

* ViewerGenderConfusion: There's no question about Yuki's physiological sex--Yuki is most definitely male-bodied--but is Yuki an MtF transgender girl, or a CampGay boy who likes crossdressing?

* MarySue: Kaoru can come off as this, given that her character traits are "perfect" in that she is a tall, beautiful, buxom, AcademicAthlete that just so happens to have feelings for Masato.

* TheScrappy - Masato, due to the way he treats Yuki and Kaoru.

* LoveTriangle: [[spoiler: As the manga goes by, Masato develops feelings for Yuki, despite telling himself that Yuki's a guy; all the while having feelings for Kaoru. At some points, it seems that Masato seems to love Yuki more than Kaoru, however, the last few chapters makes it feel as if Masato never liked Yuki and he winds up with Kaoru.]]

* FanWank: Some of the theories about Yuki "really" being biologically female can reach these levels. The manga was even encouraging some of the early fanwank, since even Masato wasn't sure Yuki was really biologically a male, and a couple of times tried to catch Yuki changing to verify it (although he either chickened out or was thwarted).

* ViewerGenderConfusion: There's no question about Yuki's biological sex, Yuki was most definitely born a boy, but is Yuki a mtf transgender girl, or a CampGay boy who likes crossdressing?

* TheScrappy - Masato, due to the way he treats Yuki and Kaoru.

This is despite the fact that the manga has gone so far as to have Masato see Yuki naked and ''sitting in his lap'' at one point, and he still thinks Yuki's a guy.

** At the very least, he's ''finally'' manning up and telling the truth, even if he did take his sweet time about doing so. YourMileageMayVary on whether that's enough to [[RescuedFromTheScrappyHeap rescue]] him or whether it's too little too late.
