But it was Nina that caused the greatest emotional reaction from Fon Fon. Granted, it was partly because of guilt, and I don't doubt that if Felli or Leerin disappeared in the same manner, Fon Fon would worry quite a bit. But so far, Nina has been made out to be the main love interest, with the scene when Fon Fon fainted on Nina's breasts near the beginning, the classic love-hate-love transition, the mid-air hug, and most of all Felli's jealousy at how Fon Fon looks at Nina at present. They now seem to share a bond that he does not have with Felli. I'm not sure about Leerin though, since we have barely seen her interact with Fon Fon.
