I feel bad for her too, but then I just had a sudden thought. Maybe Isabelle likes being in town hall all the time and never leaving except for on event days? she seems pretty much married to her job, and a workaholic, so I don't see any reason why someone like her would want to leave the town hall for even a second. Now that I think about it, it's probably in her character not to want to leave the town hall every so often, except for mayoral things or secretary things. So i'd imagine most likely she's probably happy that way. I mean it's quite weird that she even sleeps there, but again like I said she's seems like the "married to her job" type and that backs it up further haha. She's still cheerful despite it all, and never seems to have a complaint, so I feel like part of her is happy like this.
