So, had to figure out what pairing I shipped hard enough to want to do for this challenge, but wasn't weird or random enough that I wouldn't get weird looks. This is what I came up with.
LelouchxCC (Or C2, depending on what you want to call her)
Why her out of the harem that is Code Geass?
Well, I never really felt the whole Lelouch X Kallen thing... Kallen seemed to be more in love with the idea of Zero than Lelouch himself. And Lelouch X Shirley... for one, Shirley's too nice, for another, they couldn't be together. Shirley's too innocent to be caught up on all of Lelouch's shenanigans.
With Lelouch and C2, she's been involved from the start, and was the constant companion of Lelouch. She knew all of what was going on, and was never deceived by him, and in the end, it feels like it was her who he loved the most.
