No but you have to imagine:

Freaking Cardverse AU. Ludwig and Kiku are sitting somewhere doing royal stuff

And they just kinda sorta scooch closer

And they're really near each other

And then

Freaking Feliciano jumps out of nowhere and shouts, "sO WHEN'S THE WEDDING"

((And then all Ludwig's doing is embarrassed sputters and Kiku's all "but we just had a political marriage, what are you talking about")
