Also, daily suyori maintenance job means not everyone can afford to have a glorious, shiny, moldy, odor-free outhouse. No one else in the village has it. Danbi feels bad for being the only one who has it. Because he’s been using an odor-free outhouse all his life, however, a smelly outhouse squicks him out MAJORLY.
If he were visiting someone else in another town, and his host didn’t have a nice moldy outhouse, he would honestly prefer to go behind a bush. Or possibly bring some pine branches and magic up the piney scent to the max, as a gift to the host (not that the scent would last long). He prefers not to hurt the trees too much, though, if he can help it.
