Ending ain't bad per se, ends on a happy note, which is always good in my books.
But it could really have done better.
Side Characters like the Queen Hadomu, Lunarre the Great Thief, and a couple of others just get shafted because of the ending (which I felt was rushed tbh) and don't get any resolution so to speak.
But for what it's worth, it's a good ending considering the author only had 3~ chapters to resolve the story, but a far cry from a proper fledged ending. [Side note, I definitely feel like this got axed]
