If I keep talking about it you might overload with angst and sorrow at how all your OB partners leave or are less than substantial for your tastes. We don't want that~

Well I mean pairs for me have to look good and feel good. I enjoy angst and a trial to overcome, LoK speaks for itself. With KakaSaku it's Kakashi's neglect and the difference in age may also be a thing, but secret romance is pretty sexy if done well. Arya and Joffrey have a LOT to overcome to work, but I do think if given time they could really mesh together. I think Cersei is out of Petyr's league as far as romancing is concerned, one wrong move could render him without his own 'coins' if you catch my drift.

Because LoK has no Felix to start, and Felix is fabulous. The closest thing to Cosima we'd get is Jinora.
