Me, Cue: Panicked screaming. (It just felt right.)
Being said, the whole 'gave up true (arguable, prolly) love for the duties of the crown' hits like speeding Truck-kun. Ouchies. I saw a comment about 'bi-Mom', and wonder if that's wishful thinking. In that kind of scenario, especially if it's literally 'this is how we (Sheep Country) survive', no one asks or probably cares; cement the alliance, produce heirs - everything else is secondary. I say this so everyone else who reads this can feel as bad as I do. So, take that. (?)
Given Momo is youngest daughter, I wonder if the author will use that inherent (or, maybe, disinherited) wiggle room to make their social-status-bucking romance work. I think doting elder sisters + Momo being the charge-full-speed-ahead(-into-Aki's-bum) kind of Princess she is, it will be a lot of willful clashing, a couple chapters of Momo being defiant and Aki being cowardly (and getting support from Sakaki and Kiku) and some avoiding of eachother, and then Momo will win as usual - she's the protagonist, after all!
I don’t think Aki will be Secret Wolfa Princess™, as her relationship with the other Wolfa girl seemed too casual for her to be royalty – though this is based on the ‘relatively restrictive European-type(ish) royalty culture of the Sheep Country. Did the Wolfa royal family let their emotionally stunted daughter(s?) flirt with random Wolfa girls they meet at church(-analouge?)? Maybe. Though if Aki were Secret Wolfa Princess™, I’d expect at minimum more internal monologue about ‘see, being a princess sucks, that’s why I quit!’ or similar. And probably less "OMG butlergirl can't be with Princess! Scandal!!!", to be honest...
