I know this is a word that probably will sound weird, but your story was actually cute XD. You made the majority of the story sound unique rather then just re-hashing the extra chapter, and showed more of Hilda's personality.

I was actually hoping the story wouldn't end the way it did, just because it seemed obvious, but it was satisfying nevertheless. Stories where Miria is actually happy don't come very often, so it was worth it :P

That side-story in the manga was so sad... ;; nice job.
