Saintess got stripped of her title and banished to live like a nun while being a single mother at a monastery. She got off lightly compared to the others, her own fiance/husband being sent to work at the mines; though I guess her being a status-seeking social climber isn't really much of a villainous attribute aside from the fact that she plotted with the others to betray Noel. I still didn't get to see the prince's dark side though. Don't tell me he's just some hapless weakling figurehead?
Very easy outcome for Noel since she was never a love interest, unlike some others who cried "NTR!!" at the start initially thought. She's just a childhood friend, key words childhood and friend. I guess some people have gotten too used to seeing childhood friends as automatic love interests.
That said, the saintess's unborn child is still a potential pretender to the throne if they don't abolish the monarchy. I'm not saying they should kill the child, but the same can not be said about letting Stella raise the kid, who she might use as a tool of revenge years later. I suppose turning Stella into a single mother is part of her punishment, but it might be better to just have the kid be raised in an orphanage than by someone who has a motive to do it badly.
