Only at first, the queen and princess get expelled to a island for sinners, the guy she was cheating with arguably should have been executed (he was selling women into slavery) but get's sent to a monestery that seems to be closer to a prison if you get my drift, considering he's a gigolo that's arguably a fate worse than death, the king abdicates the throne as he was partly responsible for tolerating his wife and daughter's actions and one of the 2 princes ascends the throne.
As for the fl's family, the father and mother were sent to prison for some of the crimes they participated in with the queen, the son becomes the next duke and unusually for a series like this, actually becomes a better person eventually getting on good terms with the fl.
