Kamui/Yuzuriha is certainly adorable in many ways, it just is never done in fandom. Which saddens me on several levels.

Personally I've never really seen the appeal of F/K, but it's the 2nd most popular pairing after S/K, so I keep it quiet lest I be smote. >__> I want Kamui to be emotionally well adjusted! Keiichi and Yuzu are much better for him. |D
