And what exactly makes the prices absurd? Don't get me wrong, the prices are not ideal right now, but they aren't absurd either. Your income goes up with each girl, making it easier to earn any specific amount of money. With the growing price, the price you pay is no longer a price of money, but a price of "time spent". The price of 2,5 million is no more absurd than it is to upgrade Bunny as your very first girl, because the amount of time you need to spend in order to get the money to get her to three stars is still comparable to what you need to spend to get your latest girl to three stars. The time spent to upgrade a girl does grow, but at a much slower pace, and it goes up slower and slower the more girls you get.
