All the Kankers are in love with their respective Eds, genuinely. But they're also, you know, the Kankers. And Eddy hates them the most while Ed is extremely afraid of them, so Edd as the polite one is the most likely to try and meet them in the middle at some point if the opportunity ever arises. But with the Kankers, the one most likely to do that is May, because she's the nicest one due to being the Bubbles of the group.

Which is probably why the Valentines day happened the way it did, but that whole episode was just crack shipping.
