I'm going to cry!!! I'll miss this series 😢 Contrary to everyone saying this ending seemed rushed or vague, I think it was perfectly paced and everything wrapped up satisfactorily. Not everyone's happy ending is marriage and children. Not making their relationship public and 'official' is very in character with the Lady Emperor, who has almost always put the country above all, and Misono, who wants nothing but to serve her and doesn't need to stand on equal ground as her. All that matters is that they are together, they will travel the world for the rest of their days (the hiyoku-no-tori with the globe as their cage), they are happy. That's a perfect ending.
