So I was half right about where this would go but that just ended up leaving me disappointed after I got my hopes up. I was fully expecting for Adelaide to have fallen for Juliet before ever meeting the prince, I was expecting for her to disappear after the engagement was broken, I was expecting her to come back in some way whether as a noble from another kingdom or as a maid to stay at Juliet's side.
I was not expecting for Adelaide to have been a guy disguised as a girl, I was expecting for that bit about finding true love to extend into same sex marriage more than I was that. It makes more sense than any yuri pairing here but I'm still a bit dissapointed.
