I was a bit disappointed that we didn't get to see her spending time with the other grandparents. I know they died young but I would've loved to at least get to see them meet their grandkids first.
Considering those were extra side stories I think they might have pressed the manhwa artist to a certain number of chapters and some things were left unexplored...I also wish we had at least seen more of Aster's new life before skipping to her brother and the finale!
I liked the main story but didn't like how the daughter's was resolved. The Duke and Dutchess die early. Also we never see the Duke's mother again?
