Fandom Old. Get off my lawn, you Tumblr brats

Seriously. I've seen a lot of fanart/fanfic for this pairing, and I have no idea how this has gotten so popular for two characters that (to my knowledge) haven't met in canon.

Not that I judge people's preferences; in fact, Bleach has one of the most diverse samplings of couplings of any fandom I've been in, other shipper bullshit aside, but I'm just a bit...surprised, is all. *is unsure*
