Meh, I was playing it the first time I let her shame drop to 0 before I reached the next town. Now I'm doing a second run, this time I have quite easily got the 200k needed for the "armor". So, a small spoiler down below:
You go to the priest to exterminate the bats/rats/spiders, and after you reach the ruins with slimes, man-eating plants and a dragon, if you're strong enough (was lvl11 when did that) and have enough healing potions and magic potions, try defeating the dragon (volnurable to Ice but has quite a lot of life, so around 10-20 shots, keep healing yourself in between). After the battle and a small talk the dragon gives you one of its scales which is worth 200k (had another 100k already from all treasures found in that dungeon).
Now I plan to see if my previous events are still there, and even they aren't, I will play the ero events according to my shame, not letting them go too low.
