I believe the fujoshi, Eila, is actually the author's self-insert. Her whole existence in the plot was utterly inconsequential. If she had been removed, nothing would have changed, apart from the shounen-ai scenes from her imagination. Keeping this in mind, I guess it's understandable why Liam actually is never shown to do anything intimate with women, despite that supposedly being one his dreams as an "evil lord". The author is either a fujoshi or a similar man, whatever that would be called, so they can't bear to have scenes with Liam getting together with women, yet they couldn't make this a shounen-ai story because the market would be smaller, I imagine. So, we get no romance (M+F), but we got the whole fujoshi character with her imagination.
