tenshi, maybe my coment was a bit dramatic...
of course a woman can be sexy during and after her pregnancy! I'm saying this since japan is pretty special, and of course kuu always gave me the feeling that family is first , and I can imagine her enjoying so much with her family to the point that she maybe won't be feeling good doing things like "love me back". Maybe something more amuroish, like Sexy Girl or Naked. Dancey songs, choreography and good image, but no more "I sit in the legs of that boy and make him grab my boobs" (love me back pv), u know what I mean now?
Anyway, kuu is smart, and I know that in one way or another she will keep doing interesting things on her career!
