Not going to lie, I really love pairing Edelgard and Dimitri, probably my favourite ship with Edelgard after both versions of Byleth. I don't know if this is a controversial opinion or not, but given their role in the game, I would have expected Dimitri and Edelgard romantic art to be more prevalent.
I think what makes this pairing appealing to me is because I know it could never be in any of the established timelines. But it is something the both of them might have wanted by one point or another. They are likely Romeo and Juliet type of tragedy if Romeo became convinced that Juliet killed his father and his love turn into absolute hatred, and if Juliet started a war because she got sick of the family feud.
Dimitri and Edelgard, the pair that could never be.
I have also seen it mentioned in another topic that Byleth and Flayn is controversial for whatever reason, don't really understand why, it isn't really that much different from Byleth and Lysithea except Flayn is likely much older than any non-green haired character in the game.
I also wonder if there is anyone who is shipping Edelgard and Rhea, because that is the most insane pairing I could think of and would be neat just because it is so ironic.
So does anyone else support any pairings of characters that are unconventional or unpopular?
