a relationship where they only communicate with tricks and gambits
Love at its finest.
For Kodama-sensei THAT is the main sexual orientation.
And as effed up as it is, just remember the guys usually get off even worse.
It is really hard to reconcile Renai Manga with the rest of her stuff, isn't it? That story wasn't just fluffy, it was awesomely fluffy and fully developed.
It's almost as if she read her own fluffy work and went "As if! That's not real lesbian life, you naiive fool! Real lesbian life is betrayal, game-playing, and 24/7 suffering!"
Which lends credence to the theory I've seen that she was disappointed in love or something after she wrote Renai Manga.
