[@Genkai] I like the plotline you have there, to be honest. There could be lots of interesting things that could happen. The only question is, which pair would we have do that one? Or do you want two pairs with the same plot? [Not that I'd think you would, but y'know] 

I think having Harry x Hermione doing the muggle world thing would be good, because they're pretty much best friends anyway and it wont be as difficult to have them working with each other if the need may be compared to Draco and Hermione, as this would cause some issues between them. If Draco and Hermione had the tutoring plot, it would be more understandable / realistic as to why they'd be conversing, y'know? c:
