Complaining about this is not wrong. It really takes forever to pay for the 5 star girls, there is a business model behind this though so it's not going to change much if anyone complains.

The event with girls you get from low income villains are kind of a problem, I'm still working on the 13.6 million to pay for Samane 5th star, making me farm dark lord is not helping of course. I would like to get an income raise while he still is holding on to the event girl, maybe compared to the highest income I could get if I would farm there.
