I reread the story and Nova was living in a peaceful harmonious world till the alphard family appenrently killed everyone and sealed her so her just letting go of her grudge because Evris and Ciel are doing the thing she did before is kind of cheap. But still all in all I enjoyed the fluff and the length of the manga makes it good for a reread if you want. Quite enjoyable even if I personally think the author made the villain backstory to dark for this to get resolved only with a few words. I mean she was locked up for at least a century after apparently everything she loved was killed and conquered.
