I'm curious, how many ending there are?
I have only been able to marry up to seven women at the same time, i dont think there are any more. if thats the limit, then any combination of those seven should be technically possible, but some characters might require other characters for marriage, so im not sure. anyway, every character you interact with in a friendly way can have different outcomes, and if you count all of those as different endings, its in the hundreds probably. but i would only count the main characters that you can marry.
