Thanks for the answer! Another problem: sometimes (e.g., if I work in the toilet behind the dorms at night, or if I fail to ask Kitsune's permission before leaving the house the first day I submit to her), I suddenly see myself crawling on the floor, and there's no way to get up again. None of the NPC's seems to notice that, so it doesn't seem to be right: apparently it's a bug. Is there a way to fix that and stand back up? The only way I found was to restart the entire game by resetting the progress...
