Really? Rolf and Nei? I think I wrote a Rolf/Nei story when I was about 12 or 13 years old, but now they just seem too... sibling like. Where is this manga you speak of??
RW - Yes, his reaction is hilarious! Who wouldn't though? I love how innocent Nei is of it all, too. Perfect! Rudo doesn't seem to care much. See? He needs someone to warm his heart! Like a sweet doctor!
