I assume the Black Knight took care of the debt? If not, I can see why they got into a debt in the first place 😂
they indirectly cover it here: Clarice was essentially the Serving staff for the entire household and they got the King's bounty for Clarice's decision. I assume theyre paying off bulk debt while keeping some for daily expenses as well as Charlotte's medical expenses. the parents are clearly both realists and Clarise is abusing mental repression, but theyre all focused on trying to save their family either through desperate or miracle means.
It will be fun seeing Charlotte meet Frost though when we get to that. That chapter is so going to just end with Clarise introducing frost (in full armor) to the family as her husband and Charlotte will shout out with glee that she didnt know women could be knights or husbands.
if this series was more absurdist, the next chapter would have Charlotte having written at least one, if not dozens of yuri knight adventure/chivalric romance novels that end up being best sellers before frost can even catch charlotte.
