Riven + Yasuo Makes Sense and Doesn't

Lorewise, they are both rivals.

I'm not 100% sure why, but I think it might be that Yasuo was supposed to protect a guy and when the guy died, Yasuo was accused because of "wind attacks" and Riven does have Wind Slash and is also Noxian, thus making sense that she would have killed that guy when she wasn't exiled bla bla bla read the lore.

So naturally they wouldn't be a canon ship because that would directly contradict the lore (but nobody that ships cares about the lore anyway).

But in game...
