YMMV / No Bra

  • Epileptic Trees: The idea that Yuki might actually really be a female, and his 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.
  • Fan Wank: 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).
  • Love Triangle: 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.
  • Mary Sue: Kaoru can come off as this, given that her character traits are "perfect;" in that she is a tall, beautiful, buxom, Academic Athlete that just so happens to have feelings for Masato.
  • The Scrappy - Masato, due to the way he treats Yuki and Kaoru.
  • Viewer Gender Confusion: 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 Camp Gay boy who likes crossdressing?
