The Tale of Two Bandgeeks

I don't know how they met, but I don't really think anybody else knows either. They've just been together for, I guess... always? Like, the Earth or the Sun or Mr. Allhei. They've just always been a thing.
Oh, no, I don't mean THAT kind of thing! I'm just saying they're always together and always have been. They aren't like one of those squishy couples like Juleen and Tyler. Or like Harold and James. No, definitely not one of those.
They're like, um, Mr. Sin and Mr. Deihj, our music directors. Kinda always together and of the same feather, if you get that.
Anyway, the two of them are probably the closest non-dating people in the school. Excluding Nick and Ashley, who are practically dating and would be if Ashley's parents hadn't found out. Oh, and also excluding all the siblings. Other than them, George and Prosper are the closest two bandgeeks you'll find.
