Given that it's rare for anything poly to take off, I get really torn being reminded that Ruby is still in the race for Aqua
I found recently that I really cling to characters who barely get the opportunity to get appreciated for all of their hard work, so I'll die if Kana doesn't get to live happily!
I guess it's not out of the question that the author does something out of left field, but tropes indicate that since Aqua has loose ends with Ruby from pre-rebirth, that they would find each other to love each other again
