Personally, I believe not. But that's just the firm opinion of everyone at Rikkaidai. If everyone was forced to tell the truth and not omit anything, we'd hear an awful lot that we wouldn't want to about their sex lives.
That's all I ask for.

(ooc: Yessssss. I also like the idea of Yukimura winning and taking Echizen to a really, really fancy restaurant with a billion etiquette rules. Yay for barely hidden tempers!)
