I hope that the saintess will be okay... I've seen a lot of people be taken advantage of because they are told many people depend on them, and that they are the only one who can help them
Speaking of the only people to help, it's nice that the MC is like... competent and will not have to rely on the ML entirely to identify and fix the problem. Too many BL are just "useless uke is in trouble, but the powerful seme can fix it for them." And too many isekai are just like "here's a money problem. Here's someone's very Japanese guess at how accounting and economics work, and look, it succeeded." Like, I'm not hopeful that this will change entirely, but I do think there will at least be a few more steps in between to show that the mangaka is at least a little more familiar with the subject. Though, that could just be me being optimistic
