Rumah can be setup to be intentionally or unintentionally pending on if you fight Dasan and lose intentionally or fight him and lose to him unintentionally. but unintentionally only happens if you go into the quest under the recommended level and then their is the make a deal option with Dasan and weather or not you like being "cuckolded" depends on a choice you make with Kate on if you like to watch or not, all and all I think Rumah has 4 different routes for the most part if you do the NTR routes its mainly just dialog changes. oh almost forget Tia fucking Dasan cause you abandoned her in Rumah but you get lots of warnings before that happens.
If you are underleveled, you don't need to fight him.
You just need to tell people that he murdered his father.
To be fair, someone earlier did not know that if you fail the spot check to find the evidence, you can keep on trying until you succeed at the cost of energy per each attempt.
So he
thought that since he didn't find the evidence on the first attempt, it means he failed. and he refused to save scum. And then he refused to fight dasan because he was roleplaying a pacefist who would rather allow a politician (who murdered his own father for the explicit purpose of selling his people into slavery) to get into power instead of dueling him.
but... like, aside from that very extreme form of strict roleplay. I don't think anyone could actually fail it by accident.
