Other than in the Mirror Universe, is there any basis in prior Star Trek canon for the existence - however one-sided or not - of any "love interest" between Kirk and Uhura?
I'm asking with curiosity about whether Orci and Kurtzman made this up for J.J.'s STAR TREK, or if they possibly drew it from somewhere in canon.
Please note, I also am looking for actual interest on either Kirk or Uhura's part. Not just when under the influence of or "playing along with" any alien or its plans. For example, this excludes their famous "first inter-racial kiss" moment. In the plot, that was forced on them by alien influence, not enacted by them under their free-will.
Essentially I am looking for any evidence of genuine feelings or interest on either of their parts.
