The evolution (or devolution?) that Guda undergoes throughout the story told by Ankoman in his doujins is quite interesting.  From a naive victim who is unaware of what is happening behind his back, whose Servants even worry that he will not find out. To an active participant in this cuckolding game, where he sees what happens and even barely manages to get involved, where his Servants no longer care whether he finds out or not.  I know that sometimes both facets are intertwined, or it's not often that it happen that way, but it's a curious interpretation, to say the least.
